Polk Audio RTi A9 Tower Speaker

Enjoy exceptional performance with Polk's RTi A9 tower speakers (shown in black)

Meet the flagship speaker in Polk's newly redesigned RTi Series. The RTi A9 floor-standing tower speaker combines a handsome, real wood veneer finish with the kind of performance that pleases even critical listeners.

This speaker's carefully designed drivers undergo laser testing to help identify and eliminate resonance points, ensuring smooth, accurate response. Its asymmetric cabinet helps it deliver rich, clear sound by combating vibration and increasing rigidity.

The A9 also includes Polk's exclusive PowerPort® technology that reduces noisy air turbulence and increases low-frequency output. You'll enjoy clear highs, rich bass, and open, natural-sounding midrange.

Additional high-end features

Two sets of gold-plated five-way binding posts let you biamp or biwire the RTi A9 for the best possible sound. An anti-diffraction grille helps it deliver a large, three-dimensional soundstage with pinpoint-accurate stereo imaging. Adjustable spikes provide stability on both carpeted and hardwood floors.

Complete your surround system

For best performance, pair the RTi A9 towers with our recommended center channel speaker: Polk CSi A6  and surround speakers: Polk RTi A3 or FXi A6.

    Highly recommended.

    Dave from Boca Raton, FL on 4/23/2018

    Crutchfield Customer Review (What's this?)

    Bought these as the front L and R for my home theater and stereo speakers for listening to music. Powered by a mid-level Denon amp and configured 5.1. They sit on the long wall of a room that is wider than it is deep (35 by 15 feet), with wall to wall carpeting and 9 foot ceilings. Overall - very pleased with them and would recommend them highly if you have a large room and sufficient power. As others have noted, they are large and heavy. Initial setup is difficult because of this, and I've had to move them from a house to an apartment and that was a huge nuisance. But they are the first speakers I've ever owned that completely disappear, in other words, when the music is playing at moderate volume, you honestly cannot tell where the sound is originating. That's how good the imaging is. You truly do hear things you've never heard before in familiar recordings. If you think you will be moving after buying these, SAVE THE BOXES and the packing material (styrofoam). Get a friend to help you stuff them back into the box. They are each 80 pounds and roughly the size of a Great Dane.

    Pros: Tremendous sound imaging, separation, range.

    Cons: Large size requires assistance for initial setup or moving.

    Great speakers

    Rene from Schenectady, NY on 4/15/2018

    Crutchfield Customer Review (What's this?)

    These are big, and I was worried they were too big for my room, which is around 13 by 17 - out of the box, they were a bit harsh and muddy. But it looks like they just needed some breaking in. I think I have about 12 hours into them, and the sound is getting really, really good. Separation of the instruments is more than I have heard before, and the sound is full and very satisfying. And amazingly, when I am using about 70% of the AVR's power, the speakers project the sound into my kitchen and it is like having nice sounding speakers in the kitchen. Granted, the kitchen is fully open from the front of the house to the back, but the family room is around the corner from the kitchen. The speakers are big and heavy, but the biggest challenge for me was getting them out of the boxes, They were wedged in so tight I had to fight to get them out without taking the box apart. I moved them into the house and set them up solo. I am very pleased and expect them to improve a bit more based on what I have read about speaker break in. But even if they do not, I am very happy. Initially the highs were pretty harsh, but they have smoothed out really well. I am using a Denon AVR-X6300H, which is rated at 140 watts per channel.

    Pros: Sound great, good separation, look nice

    Cons: Hard to get out of the box :-)

    Best Speakers I have owned.

    Tony Cannizzaro from Selden, NY on 4/15/2018

    Crutchfield Customer Review (What's this?)

    For the price these are an incredible deal. I upgraded from the Rtia 5's where after a break in period turned out to be excellent. What I didn't live about the 5's was that at times I could hear the lack of low frequency response making them sound thin at times. The 9's do not have this issue, they go deep and never seem to get boomy. The fact that they are very tall makes voices seem to be floating up high and centered. I am only driving these with a Sony 100watt A/V receiver and they have no problem. So I sm not sure why some reviewers say they need lots of power. I do however have them slightly EQ'd. My receiver actually has a midrange adjustment, so 2.2k down -2db gives almost perfect results. I do agree with a lot of the reviews stating the lower treble is a little bright. EQ completely fixes that. Bottom line is wonderful speaker with just a slight tweak gives incredible results.

    Pros: Incredible imaging and tight bass.

    Cons: Very large and heavy

    Rich, warm, and full sounding!

    Daron from Vista, CA on 4/8/2018

    Crutchfield Customer Review (What's this?)

    Exceptional customer service and support as I sought to upgrade my stereo system and re-discover the joys of vinyl. Speaker selection was one of my biggest challenges in chasing the purest, fullest and warmest tones. CJ was awesome, listened to where I was trying to go and helped guide my purchase with invaluable insight. These speakers are an incredible value for the money. I'm still in the break in period (less than 24 hours total time), but already they've started to bloom and open up. The sonic purity is amazing, full bass and rich tones....and they look great to boot. Really, really happy with my selections and purchase. Thanks Crutchfield!!!

    Pros: Exceptional value. Versatile across a broad range of music genres. Standard and bi-wiring/bi-amp options. High quality finish and superb craftsmanship.

    Cons: They are quality speakers and accordingly they are hefty in weight. You need a good amp to get the full benefit of these beauties.

    Incredible Sound

    Excellent speakers

    Stan from Emmaus, PA on 3/23/2018

    Crutchfield Customer Review (What's this?)

    I purchased these speakers from Crutchfield two weeks ago. I have about 50 hours on them. I have them bi-amped at 200 watts a channel through my emotive xpa 5 gen 2. I believe these speakers shine when properly powered. My previous towers are a pair of boston acoustics vr3 towers which have a pair of seven inch woofers and a four and half inch midrange and a metal dome tweeter. The rti a9's were better right out of the box compared to the old towers. The imaging, range and soundstage are excellent as well as the overall tonal balance. Bass is more than adequate, the midrange and highs are very good as well. I have seen reviews complaining about lack of detail in the midrange and highs, but I believe that comes from these towers being underpowered. I am very happy with my purchase and thanks to Crutchfield for excellent customer service. If you are considering these towers and you have enough current to drive them I think most people will be happy with these speakers. Give them a try, chances are you will really enjoy them, I know I am! And the finish on the cherry cabinets is amazing, they look like a high quality piece of furniture. Good job Polk.

    Pros: A whole lot of speaker for the money.

    Cons: Heavy, but to be expected with a high quality speaker.


    Eric D from Olive Branch, MS on 3/21/2018

    Crutchfield Customer Review (What's this?)

    Amazing sound. Bass seems a little light but I believe its because I`ve all gotten used to un-naturallly elevated bass levels. Awesome speakers...clean and crisp.



    "Bang for the Buck"

    Andrew from Greensboro, North Carolina on 3/18/2018

    Crutchfield Customer Review (What's this?)

    5 Stars. I am about 20 hours into the break-in period on these beauties. I have a 300 watt McIntosh amplifier and these speakers really handle the watts with no problem. In fact I find as I push towards 300 watts on the meters the db level is so high I start backing off on the volume. The sound starts to rattle the prints on the wall in the next story up in my house from the bass alone. I have them bi-wired with a very nice DH Labs silver sonic cable. If you buy these speakers make sure you break them in before you judge the sound. They get better with time. These speakers have very nice replication of a live performance. They sound like they should cost much much more. I am thankful I got such a great deal at Crutchfield and now have the backing of a very knowledgeable staff if needed. I would say buy these speakers if you are looking for a great bargain and awesome sound. This is truly some nice bang for the buck.

    Pros: Nice bass, the mid range and higher frequencies are well done. Cabinets are wood veneer. I have the cabinets in black. Most models in this price range do not have cabinets this nice. Handle power up to 500 watts providing a speaker that can operate with less and be capable with wattage...not many much higher-priced speakers can handle this much power without spending more money...

    Cons: The grill design needs a re-design. They "push in" and are difficult to remove.

    Just plain great sounding speaker

    Dan from Niles, MI on 3/14/2018

    Crutchfield Customer Review (What's this?)

    All I can say is wow. I use them for two channel music only have them paired with a Yamaha 801 amp and the sound is amazing reall happy camper

    Pros: Really full and rich sounding for the price really any price for that matter

    Cons: None that I can think of

    Fantastic speakers. Love them.

    Anonymous from Mesa, AZ on 3/7/2018

    Crutchfield Customer Review (What's this?)

    Love them. Was going to get the A7's but at the sale price form Crutchfield the A9's were the same price as the MSRP of the A7's. I have only had them a few weeks so I haven't cranked them up a bunch yet but the sound is great. The finish on the Cherry cabinets is very smooth and looks awesome. I was a little apprehensive of the delivery process but Cruthfield and UPS freight were both very accommodating getting them to me. They are heavy and difficult for one person to unpack or to move them in close to your TV stand but you can do it with just one person. Open the bottom of the box and pull the box off the top of the speaker instead of lifting the speaker out of the box. I love the fact that the mids and tweeters are higher up in the cabinets. They line up with your ear level when setting on the couch watching TV. That makes the sound much brighter and more direct to your ears. TV sounds great on them as well as music. My amp (Denon AVR-X2300W) might be a bit under powered for these but I will just bi-amp. Nevertheless they sound great. The highs are not harsh and they have good bottom end. So far I have decided to not add a sub yet because the bass is good enough in these speakers. But I might add a sub later? If you can afford these I don't think you will be disappointed.

    Pros: Highs are not harsh. Speaker location in cabinet lines up with ears when sitting on couch which makes them sound better. Quality construction. Cherry finish is really nice. Price point is great. Looks awesome in your living room. Good amount of bass. No subs necessary unless you want them. Sound good with music as well as TV and movies.

    Cons: Heavy. Larger than I thought. Bass port on back that makes them stick out from the wall farther than planned but it not too bad, maybe about and extra 4 inches or so.

    These speakers are powerful! They provide top notch sound and look beautiful! No complaints.

    Pros: Attractive cabinets 500 watts Incredible sound imaging

    Cons: Heavy Require space because of depth

    BIG in every way! Great value!

    Robert from Bridgewater, NJ on 2/27/2018

    Crutchfield Customer Review (What's this?)

    BIG speakers with BIG sound for BIG rooms! Although primarily a home theater speaker, as in my case, they work well for hi-fi stereo. As others have mentioned they really sound best with a strong amplifier with lots of headroom. I'm currently powering them with a vintage (1978) Pioneer SA-9500II high current dual mono integrated amp. I don't think the low cost surround receivers of today will be able to do these towers justice. Over inflated watts ain't gonna cut it, current matters!! Out of the box, their sound is a little forward and a little bright but as they break in, the low end is starting to catch up. The bass response is tight with great extension. The build quality and finish (cherry) is gorgeous, like beautiful furniture! The on sale price at Crutchfield I paid is and absolutely incredible value.

    Pros: Clean detailed sound, price, power handling, gorgeous looks.

    Cons: Craves big power, very heavy (actually a pro for sound quality.)

    what an upgrade

    I replaced an aging set of BOSE, what an upgrade. Even my sister who could care less about sound quality was impressed. The BOSE ended up being neglected surround sound speakers.

    Pros: amazing sound, great looks

    Cons: none

    Crutchfield Customer Review (What's this?)

    Speakers arrived fine. Hooked up and no problems. Not much bass from them alone but do sound good. Maybe need a little more breaking in possibly. The only gripe is with Crutchfield sale pricing as of now I can buy these for much less than I payed for them last year...

    Pros: Sounds good but needs more power...

    Cons: Heavy

    very high quality speakers, plus one of the best customer service I've ever had in years from Crutchfield.

    Pros: solid build, nice mid and high.

    Cons: not very stable due to the design, can have a bit more bass

    Outstanding sound for the price

    Doug from Andover, MN on 2/6/2018

    Crutchfield Customer Review (What's this?)

    These replaced a pair of Klipsch towers. Though a little more subtle on the highs, the Polk A9 provides better detail. Better midrange & vocals. The bass extension is amazing! Similar in Sound to a TML design cabinet.

    Pros: Excellent cabinet design. Real veneer finish. The Black cabinet is a thing of beauty, photos do not do justice.

    Cons: None

    These speakers are great. 2nd set. One negative comment someone posted is these can't handle the power. Not true. I think the person amp can't put out the power. These speakers want power. I am running these with two 500 watt carver amps one amp per speaker. No issue.

    Pros: Super sound for a big or little room.

    Cons: Do to the shape they are hard to move around. But can easially live with that.

    brandon m from Evans, GA on 1/21/2018

    Crutchfield Customer Review (What's this?)

    These speakers are very good. Mine are powered by the Onkyo TX RZ810. Room size is medium. I listened to elacs, psb; moniter audios all priced equal or above the polks. THE pols are by far the best bang for your buck. The biggest thing you can do is not play them on direct mode. Almost all speakers sound better music wise in 2 channel mode where you adjust the treble and bass to your liking trust me. they do need power but make sure you buy a power supply amp or reciever with treble and bass adj. like the onkyo you will love the sound.

    Pros: great bass lively sound

    Cons: none at this price

    Crutchfield Customer Review (What's this?)

    The Polk Audio RTI A19 floor speakers are totally awsome. I had the A7's and they are very good but the A9's are more full sounding and will blow you out of the house when hooked to the Onkyo 810 receiver and the Polk Audio CS4 center channel. Also have them hooked to the Polk Audio RTI A1's surround speakers and watched Hacksaw Ridge the movie and it shook my living room and the cherry color really looks good. You cannot go wrong with Crutchfield and their help and return policy. Thank you for great customer satisfaction and knowledge of their sales people.



    Gorgeous cabinets, a bit on the bright side

    Anonymous from Blountville, TN on 1/12/2018

    Crutchfield Customer Review (What's this?)

    I've had these RTI A9's for a couple of weeks now so I thought I would offer my opinion hoping that it may help someone considering these. First off, we got the cherry veneer and these are absolutely gorgeous! They are large of course, but what a finish! They look awesome! Sonically, to me these are very bright speakers lacking a bit in bass and midrange, especially at lower volumes, with kind of sharp highs. We're using these in a basement area 24 x 32 with coated block walls, lots of furniture, and totally covered with oriental rugs so the room is partially to blame. My goal was to build a system that could be used for both HT and 2-channel. My previous system was only 2ch with an Adcom125w/ch amp and preamp driving Infinity Kappa 6's. At first I connected the RTI A9's my wife immediately asked where the bass was. I had to adjust the Adcom tone controls to tone down the highs and boost the bass a bit, but they sounded decent. Highs were still sharp compared to my Kappas. I then received my AVR, Onkyo RZ810. Lots of options, but still bright. A lot of people suggested Parasound so I now have a 275w/ch amp driving them - still bright, but capable of delivering volume levels that can fill a large room with no issues and minimal clipping concerns. I added a Klipsch sub which also helped, but the mid's still seem lacking to me. Bottom line is, would I buy them again? I think so for what I am trying accomplish.

    Pros: Fit and finish, size, detailed highs

    Cons: Lacking bass, solid mids.

    Tall, Slim, Sound Great!

    Cory from Oxford, OH on 1/11/2018

    Crutchfield Customer Review (What's this?)

    Probably kind of early to review these, but I've had a month or so to listen, so I figured I would before I forget. I have them bi-amped with an Onkyo RZ810 and running them full range in a 2.1 set up right now with a 10" ported sub. 1. At normal listening levels my sub rarely kicks on and I don't notice it being gone at all! These have nice mids and pretty good low extension! 2. These are my first big towers and I immediately notice with the tweeter and mids up 4 feet off the ground, they are much brighter and elevated (literally) when I listen to music. 3. I'm assuming these can handle all the power my receiver will give 'em, but I'm still breaking them in at low to moderate levels. The more power, the better with these. 4. These are much narrower than the big Klipsch towers, but probably just as deep. They have a nice slim look when viewed from the front. 5. Packaged very well, delivery was quick, I have no complaints, they sound GREAT, and I'm excited to get em broken in and crank em up!

    Pros: Slim from the front view Crisp Highs Very good lows, I'm running them full range The more power the better

    Cons: none!

    Zoo from San Antonio, TX on 12/23/2017

    Crutchfield Customer Review (What's this?)

    Exactly the size I was looking for. My entertainment center was lacking when I bought a 75" 4k TV. Had a space in-between the center stand and the ends. And these speakers fit perfectly. Now it looks like it was made that way. Plus the speakers aren't bad either. I'm not seriously into the sound aspects of music like other people are. As long as it sounds good, I'm ok with it. However, my amp is from 1990. Yep, it's 27 years old!! So I think I'll probably be replacing it in the near future. I'm pretty sure that I can get the best of these speakers with a newer amp. Excellent packing. One box had a good size hole in it when it was delivered. But no damage. When I unpacked it, really thick Styrofoam and wrapped it plastic. My surround sound speakers sound like crap now. Guess I'll be replacing them too.

    Pros: Really look great. If you have minimal space, these will do it.

    Cons: Could use a little more midrange and high notes.

    Polk RTi A9 vs Klipsch RP-280F

    shahaliegh from Nashville, NC on 12/5/2017

    Crutchfield Customer Review (What's this?)

    I bought a set of RTi A9 speakers just over 2 months ago. They showed up in three days and looked beautiful out of the box. The "push on" front grill was a little of a pain but it held on nicely. I had spent a great deal of time reading reviews and understood that I would need an amplifier that would be able to drive them well so I bought a Yamaha 3070 rated at 150 amps per channel and bi-amped them. I drove them gently for about three weeks before opening them up. The mids and highs sounded very good, but I couldn't drive them loudly without clipping the amp and never really got the tight Bass I was expecting from the the7 inch drivers. Carefully read and understand articles on speaker sensitivity and amplifier requirements for speakers. If you want to drive these speakers with out clipping your AMP you will need a very large and powerful amplifier. more then the 300 I have. After almost 2 months I called Crutchfield and replaced them with a set of Klipsch-Reference-Premiere-RP-280F-Cherry. Crutchfield sent out the new speakers and took the Polks back no questions asked. Thank you Crutchfield! They showed up after six days and were also beautiful out of the box. The magnetic front covers are great and they hold in place very well. I bi-amped them and they really sound great. The horn tweeter is very crisp and can reproduce highs at painful levels. The two 8 inch speakers provide full mid and with proper adjustment crushing bass. I have a very large space. 35-25 with 10-18

    Pros: They are very well made and the cabnet is rock solid

    Cons: The Polk speakers need an insane amount of power! buy with the understanding that you will need a very powerful amplifier

    They sound ok. I was looking for better highs and mid range sounds. With two mid range speakers I thought it would be much better in that area, (not so). Great bass response. I have some old Kenwood LSP 9000D 4 way speakers that sound a lot better, (they are 37 years old. I am still thinking about returning the Polks. I was quite a bit disappointed after I heard them. Can anything be done about my disappointment?

    Pros: Great sounding Bass

    Cons: muddy sounding mid range and highs

    Crutchfield Customer Review (What's this?)

    As the surround sound system I have produces only 100 watts per channel (Sony STR-DN 1060 which I also bought from Crutchfield) I was concerned if that system could drive these awesome speakers which are rated to handle 300 watts. Well my "little" Sony did just fine. Shakes the man cave and does just fine with movies or music. Great highs and deep bass. I also have a Polk subwoofer and am not sure if it's really needed as the bass produced by these speakers is awesome.

    Pros: Great highs and lows. Beautiful cherry finish.

    Cons: None other than being massively heavy and they are large so you need a pretty good sized room to deal with the size and sound.

    Bought these for impact bass, and they deliver. I do use a sub to fill the deep bass, but the A9's have great tight/punchy mid bass. I do find them a bit forward in the upper range, and I'm pondering how to tame that down. I'm not finding them to be particularly power hungry, 89 or 90 db/w/m is not inefficient.

    Pros: Excellent transient bass response, pretty good at everything.

    Cons: A bit forward in the upper ranges.

    Wonderful Tonal Range

    JM from Las Vegas, NV on 10/10/2017

    Crutchfield Customer Review (What's this?)

    It was time to upgrade our 43 year old Wharfdale speakers. The New RTiA9's met our requirements and once Bi-Amped proved to have a wonderful overall tone and a clarity that meant we hear subtle sounds that had been missing for a number of years. The base output delivers a full deep range without detracting from the crisp mid-tones. We are very happy with these speakers, they not only sound great they look good too. They were shipped in the original cartons and arrived in good condition. The Polk user manual could have benefitted from more information about Bi-Amping, it was what I would call, "a minimal user guide".

    Pros: Wonderful tonal range, good clarity in the mid and upper ranges. Overall balance is good and the speakers benefitted from being Bi-Amped. Nicely packed in their containers which provide good protection for shipping.

    Cons: User Guide is minimal. No information about the best wiring (which posts to use for each output) for these speakers when being Bi-Amped. Needs two people to safely unpack the speakers from their cartons.

    Crutchfield is an amazing company. The professional reviews were spot on by the Team at Crutchfield. The speakers arrived to my home in Oklahoma City in perfect condition. I was totally blown away by the rich highs, mids and lows that projected from the Polk Audio RTi A9's. I am driving them with a Vintage Marantz Model 2325 that I bought new in Austin Texas 1974. The workmanship is awesome. I highly recommend these speakers.

    Pros: Excellent sound and beautiful workmanship.

    Best Floor Standing Speakers

    Jeff from Cherryville, NC on 10/1/2017

    Crutchfield Customer Review (What's this?)

    I bought these for my son who just bought a house. I already have some myself so yes these are great speakers, I have had a pair for about 10 years now and they sound amazing. Polk really knows what they are doing with these higher end speakers. For the money these are highly recommended. I also have some SVS equipment and they are truly exceptional but cost way more and sound just as good. I push these through a high end Yamaha receiver which is rated a 150 watts per channel and my son has an Onkyo 135 watts per channel so you need to pump the power to these to get the great sound they are capable of. Again they are for the money the best floor standing speakers around I should know I have bought two sets of them.

    Pros: Amazing clarity even when turned up loud. No distortion noted.

    Cons: None as far as I am concerned they are perfect.

    Great speakers !!! Awesome sound. Highly recommend them. Crutchfield is the best !! Got the speakers 2 days after ordering them. You've got to love Crutchfield. Regarding the speakers, I called Polk Audio & they recommended a minimum of 200-250 watts (RMS @ 8ohm). These are not high efficiency speakers & not intended to be. Right now I'm driving them w/ a 100 watt receiver & it's not enough for ultra clarity. You really need an amp & pre-amp. I'll be doing that soon.

    Pros: Great Sound !

    Cons: Need minimum of 200-250 watts (8ohm).

    BIG speakers require BIG power

    mICHAEL from Lakeville, MN on 6/7/2017

    I originally had POLK Monitor 70IIs, driven by a beautiful sounding SONY STRDN1040 AND with a PS110 sub being . I then purchased these and was to can't run a musicians amp to power home speakers." When I'd ask "Why NOT?" i GOT A LOT OF VAUE non-PHYSICS ORIENTED RESPONSES OR NO RESPONSE AT ALL. wELL, THE SOUND WAS WONDERFUL. sO WONDERFUL THAT i BOUGHT another crown xls1502 AMP AND RAN THE AMPS IN BRIDGE MODE TO DELIVER A STAGGERING 2,100WATTS TO THE SPEAKERS!!!!. These speakers can handle 500 watts. But the 1050watts/channel(most would say overkill) made these speakers sing like no other!!. ALL my musician friends are in awe of my setup. It's not(primarily) that I can make my townhome development shake when I crank the volume....but the separation of sound and TIGHT bass to midrange is unparalleled. I would say the POLKS lack a bit upper register "sparkle" heard in speakers that have something driving the treble other than a standardand dated, neodynium magnet with a silk tweeter. Perhaps this is why Polk changed their tweeter material on their latest speaker lineup; getting up to 40khz instead of the 26khz from the rtia9s. i I am quite pleased with the speakers AND the "YOU CAN'T use that CROWN musicians amp to power home speakers." Class D CROWN XLS1502 amp has come of age. Many high end amp makers: Acoustic Research, Mark Levinson, use CLASS D technology quite effectively. These amps are LIGHTER, RUN COOLER, ARE WHISPER SILENT FOR ME and pack a PUN

    Pros: Look like a piece of furniture. Sound is fantastic IF powered sufficiently. sEVEN DRIVERS CREATES A "WALL OF SOUND, Phil Specture would be envy.

    Cons: Upper treble lacks a sparkle heard in other high end speakers. These things are HEAVY

    Great Speaker for all your needs

    Upgraded my Polk RT2000p's. Still a great powered tower for Movies. The A9's are better in all ways. Fit and Finish, Detail, and controlled depth. The only thing to remember is this will need a dedicated amp. no receiver running 7 speakers will do well with the power they require.

    Pros: Great detail and depth. Fit and finish Large -Yes this is a good thing.

    Cons: Needs a dedicated amp to sound its best. 200W Min Really needs magnetic grills.

    Awesome speakers!!! In my opinion they're power hungry! I have them biamped with onkyo 810 receiver. From lows to highs and everything in between they're perfect!! They also produce clean balanced bass too. Whether you want to use them for home theater or music or both they're perfect best bang for your buck! I still miss my carver audio set up though

    Pros: A very versatile speaker they are efficient and sound awesome. They look amazing too

    Cons: Make sure you have the power to get the most outta them

    Great Value. Big Sound.

    James from Richmond, VA on 2/16/2017

    Crutchfield Customer Review (What's this?)

    The RTi A9 speakers are a great value for a lot of quality sound. I'm very happy with them. I'm using them as front left and front right in a home theater, but also use them for music quite a bit. In my opinion, after breaking them in for a week now, I think they are incredibly well suited for home theater, gaming, and rock/rap/party music. If I had to criticize anything, the tweeter falls a little behind the bass at higher volumes, for instance in modern country music with a soprano voice, the bass gets ahead of the singer. Not noticeable at normal volumes, only when rocking the whole house. You need to bi-amp these speakers, the sound quality increases dramatically, so get a 7.1 channel receiver if you want to use these in a 5.1 system like mine. Or put more generally, make sure you have two more output channels on your receiver than you have speakers, so you can assign the extra couple channels to bi-amp these big boys. Also, these are 4 feet tall and heavy, so if you have little kids like I do, make sure you have a child-proofing plan in place.

    Pros: Great Value, Big Sound.

    Cons: Tweeter is good, but look at the LSi if you want the best.

    Incredible Range.

    Bill from Charlottesville, VA on 10/16/2016

    All I am going to say about these is this: I am a bass head. I was convinced I would need a sub with these. The sales rep told me he doubted that I would and urged me to try them before adding a sub. He was right! They have incredible range. The lows are deep and vibrant. The highs and mid are spectacular as well. I bi-amped them and they eat up every bit of 160 watts with ease. I love them.

    Pros: Great sound. Will hold their own against speakers twice the price.

    Cons: The weight. These things are heavy (75 lbs).

    Awesome Tower

    Bill from Del Rio, TX on 8/20/2016

    Crutchfield Customer Review (What's this?)

    I purchased these to upgrade from some Polk Audio RT 1000p powered towers. I was completely blown away by how beautiful the finish is on the cherry. It took some wrangling to get them set up, they are quite large. Connected them to my Marantz SR 7009 reciever and the difference in sound quality from my old towers was amazing! I started by playing some vinyl through them and the midrange came alive! The presence and soundstage these towers produced was so good, I was glued to my chair! The low end was clean and powerful with no boominess or exaggeration. They will fill a large room effortlessly and play so clean you could listen for hours with no fatigue. They do dominate floor space but it is so worth it! I have run pretty much all genre's of music through them and they sound great with Mendelssohn all the way to Metallica! Worth every penny!

    Pros: Clear midrange Great soundstage and presence Powerful and clean bass Beautiful cherry finish

    Cons: Large and heavy

    Massive power not required

    Bob from Kernersville, NC on 6/28/2016

    Crutchfield Customer Review (What's this?)

    I never thought I'd buy Polk, I always figure I'd have to go with some high-priced British or obscure audiophile brand. I've been listening to these outstanding speakers for over a month now, and am still wowed by their detail, lack of coloration, total lack of "boxiness", and evenness of frequency response. With good source material on CD or LP these speakers will sound stunning. What is most impressive is that you don't have to crank the volume to ear-busting levels to get listening satisfaction out of these speakers. And with a good-quality amp driving them you don't need 3-digit wattage to fill a room with sound. My previous-generation Marantz PM6004, conservatively rated at 45W/Channel at 8 ohms, can run you out of the house with these speakers while sounding clean and balanced. With that amp running in Direct Mode with no EQ, I find these speakers to lean just a bit more towards bass-emphasized than bright, perhaps because the bass from these speaker is incredible when the recording provides it, and partly because the Marantz tilts that direction. These big speakers produce a BIG soundstage (not talking about imaging, but rather about their "presence"). Put on some well-recorded orchestral music and you get the full symphony orchestra in your room. I'm sure I could have spent much more and not been more satisfied that I am with the RTi A9s.

    Pros: Total lack of coloration, superb detail and balance, good sound at any volume. No excessive sizzle from the tweeter, no frequency overemphasized. You don't need a massive amp, just a good clean one. Absolutely beautiful in the cherry finish. Great for any music genre. Even your spouse will hear the difference, so spend the money.

    Cons: Not for small rooms or apartments, they pump out a lot of volume. A bit subdued in the vocals. Very, very heavy with nothing to grab onto to move them around. Should have bought them years ago.

    Bought these a little over 1 & ½ year ago so I've had plenty of time to put these through the ringer. I replaced my Bose Acoustimass 7 series speaker system with these, and I've got to say my gut hurt so much thinking of how I could have been listening to these years ago. I've heard things in music and movies I'd never heard before, I just didn't know these sounds existed. If you don't have the money to buy these right now, SAVE UP!!! They're worth waiting for.

    Pros: Will fit in a thin place where normal bulky speakers wont.

    Cons: Wishing I'd bought these a long time ago.

    Anderson C from California on 1/10/2016

    Crutchfield Customer Review (What's this?)

    I got these speakers for 2-channel music listening. In making my selection I found online reviews, from both professionals and regular users, very useful. I especially appreciated the reviews that made it clear how the reviewer was using them, and what they were comparing them to. So here we go: I'm the kind of person who creates the perfect triangle, sits in the exact right spot, and listens to music in the dark or with eyes closed. It doesn't have to be loud, just clean and accurate. I also don't care about ground-shaking bass, just pure sound the way it was recorded. I bought these, together with a NAD C 375BEE amplifier and NAD C 546BEE CD player, to replace a 15-year old Yamaha mini shelf system that I bought at Crutchfield in their Charlottesville brick-and-mortar store. Given the complete system replacement it is difficult to isolate the contribution these speakers made, even though I did play around a bit with matching old and new components. Let me tell you, until this new system I have never heard music before! With these I don't just hear the music, I experience it. I'm transported into a spatial sound world where I can pinpoint each instrument and musician. It feels like watching (with eyes closed) a musical painting that is larger than my room. What is most interesting to me is that I don't hear the speakers, I only hear music. I can't believe I have missed out on this way of experiencing music in my own living room. Until now!

    Pros: I would call these neutral speakers. I have read comments about them being harsh or lacking bass, but this is not my experience. I do think placement may have to do with this. I also like how, despite their size and weight, when seen face-on with the grille on they look deceivingly small and inauspicious. Most importantly, they sound clean and accurate across the whole frequency spectrum and dynamic range. Both quiet and loud passages sound clean, complete, and captivating.

    Cons: I don't see any cons. I did a lot of research and what I got exceeded my expectations of what I had distilled from all the information I had collected. So, thanks internet!

    Great speakers !

    Polk Continues to Deliver Excellent Speakers

    WHBCTP from Stroudsburg, PA on 9/13/2015

    Crutchfield Customer Review (What's this?)

    In the process revamping man cave into retirement mode. Replaced a pair of Mirage 895is (giving to a son for his setup) and agonized between RTi A9 and RTi A7. The RTi A9 won the debate. This is a very impressive speaker with excellent mid range and high end. Bass is more than adequate and I run a Polk sub with the system. My use is about 65 % music and 35% surround sound. The surround sound speakers are Polk as well as a Polk Csi A4 center channel. Since I replaced the speakers I decided to replace the Adcom two channel amp with an Emotiva XPA-2 Gen 2. You need some power to make these speakers really show what they are capable of. A Marantz receiver serves as the pre-amp and powers the center channel and surround sound speakers.

    Pros: Excellent sound without any coloration. The cherry finish on the cabinet is impeccable. While the speaker has some size (my wife thought they were too big) as you listen you concentrate more on the sound and the size doesn't matter, all you get is great sound reproduction.

    Cons: These speakers are heavy and are a challenge to move.

    Superior quality, but with reservations

    Bob B. from Indiana on 6/27/2015

    Crutchfield Customer Review (What's this?)

    Cabinetry and construction are superb. Exceeds expectations, but you have to pay attention to all of the reviews. I knew I would use a subwoofer, so the weak low end does not bother me. Above 60 hz, the sound is pure and undistorted, especially at higher db levels. This speaker requires lots power to develop good sound. It sounds tinny with less than 100 watts rms per channel, but suddenly comes gloriously alive as this threshold is reached. Therefore, it is great for serious listening in larger room full of furniture, but not good for soft background music or small spaces. I drove it to 400 watts - the louder, the better the sound quality. The sound character is technical, as often referred to with "reference speakers", but not harsh. The spectrum improves with power, but lacks warmth at low volume. The Polk RTiA9 powered subwoofer I purchased at the same time fixed the low end issue, but not the low volume flat sound. This is a great speaker if you want to fill a larger room with high quality pure sound reproduction. Probably not what you are looking for if you enjoy vinyl and old school gear.

    Pros: Beautiful to the eye and ear, if it meets your intended purpose. Exceptional quality. Very high tech. I love this speaker and it fits my purposes. Highly recommended for audiophile with good equipment. Precise and wonderful to hear if driven properly.

    Cons: Low end is weak, and a subwoofer is highly recommended. Not for weak systems, small spaces, or soft background elevator music.

If you want BIG sound and uncompromised sound quality these are the speakers. I run a 135 Watt Onkyo receiver and I couldn't ask for anything more. What else can I say but if you are considering these speakers you cant go wrong.

    Awesome Speakers, Awesome Customer Service

    Ted T from Michigan on 3/27/2015

    Having a little prosperity coming my way, I discovered some unscratched itches; one of them was my entertainment system. I have an Onkyo home theater receiver (TX-NR807, 135 watts per channel) and had recently upgraded to a Samsung Curved TV after enduring a 30 year old box TV with green pictures. I had a Bose Acoustimass System which sounded pretty good but the sound on the center speaker was a little boxy. After weeks of shopping, I decided on the Polk RTI9 Speakers. I had visited several boutique stereo shops and listened to a number of high-end speakers. I looked at Monitor, Klipsch, Bowers & Wilkins, and several others. Of course, they all sounded good and some looked and sounded better than others. I decided on the Polks (RTi9 right & left and C6 center) which, at least in the pictures, looked pretty nice, and based on specifications delivered the same value as the boutique speakers at a significantly lower price. I then had to decide where I would buy them. Based on reviews, I finally made the move and placed the order with Crutchfield. Upon receiving the speakers, I discovered a loose screw in the center speaker. I then called customer service and received a replacement a few days later. Result: Awesome TV and Music.

    Pros: Fantastic big sound. Beautiful furniture grade speakers. These speakers sound way better than the expensive built-in sound systems of my affluent friends and neighbors.

    The speakers exceeded my expectations at all levels. The sound quality is pure, crisp and very clean with a solid bottom end. I found the use of a sub-woofer to be a enhancement but not a requirement due to the strong dynamic range of the speakers. The speakers cherry cabinets are have a positive visual impact in a impressive but not overstated way.

    Pros: These speakers provide a large sound field that fills a room in a effortless manner for both surround sound front main speakers and for pure stereo listening enjoyment.


    Look Amazing, Sound Awesome

    SeanP from Orlando, Florida on 12/21/2014

    I purchased these off of someone who bought them through I have them running off a Yamaha Aventage RX-A840 pre-amped to an Emotiva XPA-3 gen2 with 200 watts going to them. I paired them with a JL Audio e112 and they sound incredible. I pushed them a little too much when I first got them and popped a tweeter. I called Polk Audio directly (they're in California) and they shipped me a new tweeter for $60, and it was too easy to replace. First off, I have not tried them directly through the Yamaha, which is only rated at around 100 watt/channel, so I don't know what they sound like with less power, but the Emotiva definitely seems to open them up. They are a bit bright on the top end, and can sound wispy at times. They definitely need a good quality medium, as they will put all the noise from lesser quality recordings front and center. At first I had them paired with a Klipsch R-12SW which has a built in 400 watt amp. The sub hit some low notes and sounded really good, but when I pushed them to higher volumes, believe it or not, the Rti-A9's drowned out the Klipsch completely. THESE BABIES GET LOUD! I cranked One by Mettalica and the Polks were so loud I thought for sure someone in my neighborhood was going to call the cops. I sware I've never heard speakers as loud in a private home in my lifetime. I'm afraid to push them that loud now with the JL, because I know that thing will probably crack my foundation at that volume.



    First Impressions

    MSW from Texas on 12/19/2014

    Crutchfield Customer Review (What's this?)

    I've had these for a little over a week now. They replaced an ancient but well cared for pair of Cerwin Vegas. I purchased them along with a DSW660 12" sub. I have them running bi-wired from an Onkyo TX-NR828. The first thing that was evident was the clarity and brightness. They absolutely require a high quality source or medium. They bring every detail right to the surface. Playing flac files of albums I have long been familiar with revealed exciting new details I had never heard before. On the other hand, playing MP3s and most streaming sources makes you painfully aware of the compression and diminished quality. The subwoofer is an excellent pairing, but needs to turned way down for most music listening. For movies/theater purposes they are outstanding. Soon they will be joined by a CSI A6 and 80 F/X RT surrounds.

    Pros: Amazing clarity, beautiful styling, will go louder than you could possibly need

    Cons: Sometimes a bit on the bright/harsh side, but haven't had them long enough to rule out audio source as biggest factor

    Crutchfield Customer Review (What's this?)

    I have been a music fanatic my whole life and I use different speakers for different types of listening. I have my Klipsch Cornwalls on my "Main" stereo. Thats for thumping my wife and kids out of bed on Sunday morning or when I want to get the most sound out of a recording without blistering the paint on the walls. I have a set of 901s in the basement for the drunks and the kids. I had a commercial Sony Surround sound / DVD player, you know the kind with the plastic speakers and Elmers glued on speaker covers and it was mainly for the kids and it served its purpose at the time. It was finally time to put it out in a garage sale and build again. Kids in school, funds kinda weak, I browsed the bargain bin and found these Polks for a reasonable price. The ad said scratched and banged up floor model. After reading reviews on this brand and model, I liked the spec's and I rolled the dice. When they got here, they were too big for my wife to move.Together we took them out of boxes that looked like crap, we were shocked. They are beautiful and if they say thats banged up, I will eat your hat. These looked brand new, like a piece of modern art. Not B and O modern but for us they were great. Plugged em in to the main stereo for an audition and what I got was "Big Bang Boom"! They sounded great, looked great and they will proudly anchor my new surround system. Keep it up Crutchfield! So far you have a customer for life!

    Pros: Sound great and I haven't even broken them in yet. Look like a piece of furniture. Too heavy for a burglar.

    Cons: Don't leave them for your wife to move by herself or you will get skip for dinner.

    WOW! RTi-9

    MRI3T from USA/Maryland on 4/10/2014

    Crutchfield Customer Review (What's this?)

    Unbelievable sound, cabinet quality! These things are like a piece of art to look at!! Unlike me to spend this kind of money on a set of speakers, but I'm very satisfied that I did! Wish I were driving it with an amp with a little more punch (these babies can handle 500w continuous) I have them paired with a PA sub-woofer and it adds a great sound for movies as well. Separately these RTi9's are great, low-end thru high-end! I've never owned high quality speakers b4 & I would definitely recommend these! I also bought these, 1 as an open box, & the other as damaged, neither of them had any visually impairing prob. for me! The grill was messed up on the one, but I prefer them w/o the grill!

    Pros: Everything about them! Probably be the last pair I ever have to buy!

    Cons: Can't find anything yet... They seem to get better with time!

    These speakers ROCK!

    Brewmonkey from San Antonio, TX on 4/4/2014

    Crutchfield Customer Review (What's this?)

    I replaced a pair of Cerwin Vega CLS-215's with these. I was a bit worried when I ordered the A9's, that they wouldn't produce the type of bass I'm used to with the Vega's. These speakers produce PLENTY of tight, thumping bass! I listen to just about everything except country music, and I've put these speakers through a wide variety of music, and they are just awesome all around. Crystal clear, and very detailed they are. I use them for music only, and they are powered by a 500 wpc amp. They don't seem to be anymore power hungry than the Vega's were, so I would say as long as you have decent gear I think you will be fine powering these with a receiver rated 100-125 (true) RMS, and not the crappy peak ratings some companies use. Anyhow if you are considering these for music, have no fear, buy them!

    Pros: Very detailed, not bright or muddy at all. Plenty of bass when you want it. Very appealing, and in no way an eyesore.(Cherry finish)

    Cons: None. Some people list heavy as a con, but to me this is a pro.

    2.1 setup

    VitaliyG from hampstead, MD on 3/9/2014

    Crutchfield Customer Review (What's this?)

    Let me first begin by letting you know my setup. I have a 2.1 setup with a Marantz 7701 Preamplifier and an Emotiva XPA-2 power amplifier. This amp is a beast and the clean power at 300 watts per channel is really opening these speakers up. I have not tried these speakers with only a receiver, but from other peoples reviews it seems that having an additional power amplifier gives you the true capabilities of these speakers. I am using a Polk audio DSW pro 440wi subwoofer. This 8" sub has plenty of power and works great in my living room. I am using good quality wires for all my connections as well. the sub cable is a Sub-X Auioquest, I am using King Cobra XLR cables to connect my Marantz 7701 preamp to the Emotiva XPA-2. And finally I got Audioquest Rocket 44 speaker wire that I am running from the Amplifier to speakers.

    Pros: Good looking and clean crisp sound

    Cons: None so far

    Love These Speakers

    Wes from Durham, NC on 3/6/2014

    Crutchfield Customer Review (What's this?)

    These are great speakers at their price point. I'm driving them with a Marantz SR7008 Receiver and using them as left and right front speakers in a 9.2 surround setup. I've set the system up to handle high-res audio files. These speakers are the anchor for the system (also using the Polk subwoofer Pro 660wi.) I could have spent more and gotten more but I am completely satisfied with the outcome with these speakers.

    Pros: There just so darn classy looking! well as being great speakers. Crystal clear highs and lows.

    Cons: None

    Jim b. from Erie,pa. on 12/27/2013

    Crutchfield Customer Review (What's this?)

    Pollks are now 1 year old and sound so much better now after many tweaks. I started with nad 375 bee intergrated amp then bought another as I felt I wasn't pushing enough power to really hear them let alone feel them. Power was at 330 watts/channel, then added 2 Polk dsw 660 subs,the towers really do sound better with these subs, maybe a little overkill but I can adjust pretty easy with the subs volume and room optimizer. The speakers are a tad forward(midranges) but really excell on keyboards,voices, horns. I made a couple a changes at the speaker wire and clear day double shotguns(silver wire) with jumpers,made all the difference! The sound is super clear, no boom, sound stage very wide, this what I thought the polks would do with tweaks. If u have the time and money this was well worth the upgrade. These speakers have transformed so much, funny,I almost sent them back, but let them break in, then start tweaking interconnects and speakers wire as I think that a major part of what you may discover how those changes really do make all difference. I just recently changed to a emotiva xpr-2 amp(omg!!) Now this is getting serious, I LOVE MY POLKS!!!

    Crutchfield Customer Review (What's this?)

    I couldn't be happier with the purchase of these RTi A9's! I am hearing music in a brand new way. I can't believe the sound that comes out of these speakers! I'm hearing nuances in music I've been listening to for years out of an older pair of Bose 301's that I never knew were there thanks to these new RTi's! I love Pink Floyd, but OMG! it's like listening for the first time! I was a little nervous about spending that kind of money on 2 speakers, but I'm so glad I did it.

    Pros: Bi-ampable, fidelity is incredible, beautiful black finish, tall and relatively thin so they fit easier in tight areas, MADE IN USA!

    Cons: At 80lbs. each, you will need help to unbox and position them. This isn't really a "con" because I believe you would have the same trouble with any speaker in this category.....

    Polk Rocks

    Rob C from Chicago ridge ill on 7/30/2013

    I have had these for about 2 years now. They are powerd by an Emotiva Xpa-5. I plan to purchase the xpr2 600 watts/ch. I have heard many systems and this one for the price equals them. The speakers absolutely kick a££ I do have a 1000 watt sub to add to the excitement. But really for the price of these speakers you can't go wrong.

    Pros: Price looks build quality sound crutchfield carries them

    Cons: None other then they are hard to move, but I think that's a small price to pay for such an awesome speaker

    Music Lover from Ijamsville, MD on 3/22/2013

    Crutchfield Customer Review (What's this?)

    I got these speakers two weeks ago and still breaking them in. They are heavy build and beautiful wood finish look like fine pieces of furniture. Sound was excellent but seem to be under power even though my receiver is a Yamaha RX-A2020 delivers 140 watt per channel and I have them bi-amp connection. I listen to them in low volume level in early morning or late at nigh and they sounds clear and warm, I though the bass was week but since I only use them to listen to music I am not in a hurry for a subwoofer. I read other people threats saying these speaker needs more power to sound at their best so I am in the process of looking for appropriate speaker preamp. I probably keep these speakers for a very long time.

    Pros: Sounds Great ! solid build look beautiful

    Cons: Need a lot of power

    excellent speakers

    I bought two of these speakers about a year ago. Buy them. They have taken all I've given them....beautifully. I also bought a subwoofer, which I have found to be necessary with these speakers. The sound quality and power handling are more than adequate for any house. I moved my A9s to my weekend home, and recently purchased the A7s for my apartment.....more than adequate.....dont forget: get a subwoofer!

    These are my first home theater speakers, and they are very nice sounding. First thing I said when I opened the box was "wow" due to their size. I've heard complaints about them being to "bright" for music, although I don't have anything to compare them to they sound fine to me. I'm driving them with a Yamaha RX-A3020, once I get the surrounds installed, I will probably be upgrading to an external amp for these beasts.

    Crutchfield Customer Review (What's this?)

    Spectacular speakers. I bought these scratch and dent from Crutchfield and the damage was cosmetic and minimal. Definitely worth the savings. Sound is excellent. Nice balance from deep lows to high highs, as well as at a range of volumes. The more I listen, the more I like them. I'm using the small powered Polk sub with them, since it was free from Crutchfield, but it's really not necessary. My 110 watt receiver seems to be fine with them, but I'd be curious to try something bigger since many reviewers seem to recommend more power. However, I've never heard them distort all the way up to uncomfortable volumes. Enjoying them for both music in stereo and 5.1 movies with other Polk speakers. Very happy with this purchase, especially having never heard them before buying.

    I have had these speakers almost a month now and all I can say is wow!!! I was in the middle of finishing my HT when I traded horses mid-stream. I had and still do have, klipsch rf-82's when I decided to go with the Rti a9. They both are great speakers, but, I looked at the surrounds and wanted to go in the direction of the polks over klipsch. The polks sound is alot warmer to me, and they blow away the klipschs in the looks department. Very happy with my Rti a9's. Crutchfield was very easy and nice to order from. Great service.

    Pros: A great big beautiful looking and sounding speaker.

    Cons: None.

    Great Speakers

    Netman8762 from Hollidaysburg, Pa on 5/4/2012

    Crutchfield Customer Review (What's this?)

    Great speakers! Very firm and true sounding. You do need to have some power to get the most out of them I am running an Onkyo TX-NR1009 with an M-282, the Receiver does the Low end and the 282 does the highs. It sound very nice but I still feel that it could stand more power. The range on these is really nice, I have spent some time listening to vinyl and am very pleased with the results. I should also note that these speakers are BIG! You need to have some room to move these around.. Very pleased and will keep for a while..

    Pros: Great sound, true feeling. Look impressive, great sound. Great lows and strong mids. The highs seem very natural to me

    Cons: Huge, heavy and hard to move around..

    Stop wasting your time and buy these...

    Travis from Houston, TX on 7/24/2011

    A very musical speaker; could possibly be the last tower speakers you'll ever buy. The sound is very neutral and consistent from top to bottom. The bass is accurate and natural, but has the ability to take charge for more demanding audio tracks, and can go down to 20 hz quite comfortably. The Cherry Finish is beautiful and will blend well with other shades of wood. For the quality of product, the price is very reasonable. Also, they will sound very bright if under-powered. Moving them around can be awkward because of the shape and size of the cabinets, so save yourself the trouble and get someone to help you move them...use gloves. The RTi A9's are very capable speakers; however you should give just as much consideration to your other equipment. NO commercially-available receiver will do these towers justice because they have so many drivers. I originally bi-amped them with a TX-NR906 (~290 watts/ of the most powerful ones out there), and while the sound was decent, it was obvious that my receiver could not fully control the entire range of the speaker in addition to the demands of the other speakers in my HT system. I highly recommend that you use quality amplifiers (such as XPA-1's) if you desire to use the RTi A9's as they were meant to be used.



    Clear and Even Sound but Bass Needs Help

    Dono from Ohio from West Chester, OH on 6/17/2011

    Crutchfield Customer Review (What's this?)

    These are really well made and high-quality speakers, and I like them. They seem to require significant power to maximize the bass and probably should be bi-amped. Their forte is mid-range and smooth high-end but not bass. I will have to connect my powered sub to augment the deficiency. This is pretty much par for the course for Polk. Recommended, but get a sub to be completely happy.

    I got these bad boys because I like to play my music LOUD and let me tell you. My whole music collection sounds new again. I cranked up Joe Bonamassa when I hooked these up and my dear Lord !! I replaced 4 McIntosh ML-1C speakers I had since the 80's and was sad to see them go, but my expectations were more than met. They just come alive when you put the power to them. I have 2 NAD amps bridged to put out two mono sources of 300 watts and man alive, my friends sat there in utter disbelief. You aren't going to get the potential out of these if you have some wussy little receiver driving these. The crispness and spacial sound stage these things produce are stunning. If you got the space and the place, buy them now. You won't be sorry. Thanks Crutchfield, for a very pleasant experience.




    Gary from Ohio on 3/26/2011

    Crutchfield Customer Review (What's this?)

    Absolutely amazing!!! Cherry finish is spectacular. Speakers are huge and very impressive even without any sound coming from them. Crutchfield delivered on time and without any issues. I had these for a week now and am still breaking them in. I purchased these exclusively for 2 channel stereo, but since I have a polk surround system, I am breaking them in on that and they blend seamlessly. I couldn't resist putting a few cd's in my bluray palyer to hear some 2 channel stereo and I am absolutely blown away with the range of sound, I hear so much more off familiar cd's than I have ever before. I turned the tv on a jazz listening station (im a rock guy) an oh my goodness, they are awesome. the highs are there, the lows are there, and everything in between is there. I have been using these in surround mode with my sub turned off, so I can check the bass on these babies and its definately there, of course for movies you need a sub, but for music, I dont think I will. I haven't cranked these puppies up yet to some heavy Metallica yet, at least not loud, but I can already tell they have what it takes. Im so glad I went with Polks flagship model. Thank you Crutchfield, and thank all of you who post reviews to make this purchase much easier. I love my Polks.

    I never liked watching BR movies on my Sony LCD with the dinky sound. Some great floor standing speakers were in order. After a lot of research, I decided to take the plunge on a pair of speakers that would do justice to the home theater setup. The RTi A9's do the job extremely well and the double set of wire ports in the back tells you these were built for bi-amping ( It's something you should take full advantage of along with a good receiver to handle all that power. All you have to do now is put in "Apocalypse Now" on BR, cue up to the "Ride of the Valkyries" helicopter scene and experience nirvana. :)

    Do you want to bring more life into your music?

    MarkF from Crossville, TN on 1/19/2011

    I've recently bought the Marantz SR7005 receiver to push these. I've bi-amped 125 Watts into these speakers, running a total of 500 watts. I've gotta tell you, words cannot describe the sound quality that is produced. I'm hearing stuff that I've never heard in my music. They are built very solid and aesthetically gorgeous. There is now way you can get this quality of sound out of compact speakers. These might seem pricey, but like most everything in life, you get what you pay for. Be sure to at least push these with some power. Highly Recommended.

    I did a lot of web research on these speakers due to the price. Almost all reviews were excellent. After having mine for several weeks I totally agree. I upgraded from my Def Tech's BP-8's. The A9's are awesome speakers and fill the room with music. What I like most about these is how good they sound at low volume. I'm mostly a two channel music guy and my cd and lp collection has never sounded better. I also got a sub but these have plenty of bass. I'm using a Yamaha RS-700 100 watt receiver and the pairing is great. They are big 70lbs each and require special shipping but Crutchfield called me within 2 minutes to fill me in on details. Great service and great speakers. Sound great with rock, jazz. blues.

    Crutchfield Customer Review (What's this?)

    I replaced an older Bose system with the A9's. I took Crutchfields recommendation on these speakers, while the price was a bit daunting I really wanted better sound out of music and movies. I REALLY got it! My receiver is the Denon AVR-3808CI. Movies and especially music have really come to life out of these speakers. My cd collection has never had the workout it is getting since I installed the A9's. There is an extra dimension to everything that comes out of the speakers that was NOT there before. All of the sound is clear and crisp. Highs are high but not ice pick high. Mid's are.......beautiful and the lows are bassy but not muddy. The cabinets are a thing of beauty. They certainly added to the decor of my family room. They are pricey but worth it in my opinion. If you are in the market for a set of forever speakers and have the extra $, these may just be the ones for you. They certainly are for me.

    This will be the first review of these beauties, Polks web site has 3 reviews otherwise this is it, I googled everywhere couldn't find anyone with a review. <BR><BR> Anyway...I bought these by the picture and info here never heard them before, but I had a good idea this was a good choice, I have Polk momo car speakers in ALL 4 of my cars and bang for the buck NOTHING matches the preformance of Polk. <BR><BR> These monsters are heavy and extremely well built, 4 feet tall, the cabinets taper slightly, towards the back. I almost needed a dolly to move these around, I couldn't get my arms around them, unbelievable mass and build quality. <BR><BR> Stunning to look at, hard to take my eyes off of them, I have yet to put the grills on (doubt I ever will) they are beauiful and tastefully crafted and would blend into any upscale home decore they just scream power and preformance. I have the black / silver accent model. <BR><BR> Onkyo TX-SR875 140 Watts a channel is driving these babies every octive, highs,mids,bass preforms flawlessly. Understand speakers of this caliber take a few weeks to break in same as Polks car speakers. Other than the Odessay calibration of the Onkyo I have added 2db to the base for tweaking the lows the tweaters are very brilliant and clean no adjustment needed overall performance is stunning. Your home or ears cannot handle the top end sound and power these speakers can produce. At lower volumes they still sound full, deep, brilliant and powerful. <BR><BR> You will be hard pressed to find any speaker at this price range and build quality that comes close to these amazing speakers.<BR><BR> These are a bargain at 749.00 ea that preform at the 2-4K price range. Don't skimp on a receiver a 1,500 set of speakers needs a 1,500 receiver These need good clean power. Would you put cheap tires on a new Corvette? <BR><BR> The public and magazine critics have yet to catch on to these masterpieces they are so new and undiscovered. I'm loving these speakers, by far the BEST value Crutchfield has in tower speakers. Anyone who chooses these...YOU WILL NOT BE DISAPPOINTED!

    Product Research

    Driver Technology
    Enclosure Design
    Mounting Options

    Driver Technology

    Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

    Polymer Composite Woofers: The speaker features three 7" polymer composite woofers. Three 7" woofers have the surface area of a single large woofer with the low mass and acceleration of small woofers, resulting in tighter, more accurate bass response. Each woofer uses a butyl rubber surround.

    Polymer Composite Midranges: The speaker has two 5-1/4" polymer composite midranges for smooth wide-range response with low distortion. For high performance durability, each midrange uses a butyl rubber surround.

    Silk/Polymer Tweeter: The speaker has a single 1" silk/polymer dome tweeter that provides clear, detailed highs. The tweeter features mylar bypass capacitors in the crossovers to extend high frequency response and improve detail and transparency. The tweeter also features low viscosity ferro-fluid cooling with a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.

    Magnetically Shielded: The speakers are magnetically shielded, allowing you to place them near your television without distorting the picture.

    Enclosure Design

    Damped Asymmetric Hex Laminate (DAHLI) Cabinet Design: All-MDF construction with massive asymmetric cabinet bracing ensures a resonance-free enclosure for accurate sound. The asymmetric design is made from a 6-layer laminate with 5 viscous layers to create the optimal shear damping (OSD) system. The elegant styling aside, curved cabinets not only result in a stronger, more rigid and acoustically inert enclosure, but the curved walls also produce less audible coloration from panel resonances.

    Power Port Venting System: The speaker has a rear-firing Power Port venting system built into its back plate for precise deep bass response from the floor-standing speaker's three 7" polymer composite woofers. This venting system allows air velocity to slow gradually, vastly reducing air turbulence, and delivering greater bass efficiency than conventional ports.

    Note: The two 5-1/4" midrange drivers feature a sealed cabinet.

    Anti-Diffraction Grilles: The floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.


    Dual 5-Way Binding Posts: The speaker has two sets of gold-plated 5-way binding posts connected by gold-plated jumpers. Using the dual 5-way binding posts, you can bi-amp or bi-wire the speakers.

    Almost Perfect

    Written by James, IT Programmer/Analyst 2, on 6/26/2012 10:18:00 AM

    Let me start by saying I love these loudspeakers, they sound GREAT! I've used the Polk RTi A9's as my main left and right for about a year, and after a short break-in period they really came out. Music sounds fantastic. The sound stage sets the musicians realistically. They're very clear and concise, I've heard more detail from my CDs than ever before.

    I use my A9's mostly for home theater and they shine with matched speakers. Mine are set up with the voice-matched CSI A6 center and FXI A6 surrounds. The effects seamlessly envelope me. I like my movie sound loud and detailed, so I'm in it. These do that job superbly. Did I say I loved these speakers yet?

    As many customer reviews have also stated, the A9's need power. A lot of power. They still sounded good when I drove them off of a 7.1 Onkyo receiver at 110 watts, but the lows suffered some. When I bi-amped them the lows came out and really started to hit. I think these speakers would gain even more from more power and a separate powerful amp (they can take 500 watts!).

    The cabinets are very nice and the cherry color blends in well in my living room. These speakers are big, they do have a dominating presence which I love but, unfortunately, my wife doesn't. They are also very heavy, so moving them around is kind of a pain, but it's a good sign of the quality of their build.

    Positives: Clear, detailed, loud.

    Not So Positives: Wife appreciation factor, need a whole lot of power to make them really shine.

    I had a cheaper set of polk towers before and they sounded great. I upgraded to a more expensive Klipsch and had problems and couldn't get help(not purchased from you) so Im going back to polk plus the reviews are great [ James  Dec 21, 2017 ]
    Seeing these voice-matched towers at a discount was more than enough for me to pull the trigger to pair them with a previously-purchased CSi-A4 center channel speaker that I have been enjoying for the past three years. [ Myron  Dec 15, 2017 ]
    couldn't get bose 901's [ thomas  Dec 14, 2017 ]

    Time to upgrade the RT2000p's that have been so good to me for 16 years. Polk is a great way to enjoy Music and Movies. [ Mark  May 21, 2017 ]
    They're a badass versitile speaker [ james  May 21, 2017 ]
    I currently have the AT15 Cerwin Vega floor standing speakers which are 18 years old. These speaker could deliver some hard pounding base but its time for something more slim but could pack a punch. I am hoping that i would be happy with these speaker again read the reviews and its was positive. [ Judy  May 22, 2016 ]
    The best speaker by the numbers for the price and is part of a matched system [ Charles  Mar 26, 2018 ]
    I wanted large , well made speakers. The price was right too. [ Marc  Feb 06, 2018 ]
    This is the best floor standing tower speaker in Polk Audio's RTiA series. [ M  Dec 29, 2017 ]
    Excellent reviews and 40% off. [ John  Dec 07, 2017 ]
    the discounted price [ william  Nov 25, 2017 ]
    Needed speakers that will deliver good bass for music but also work well for Home Theater. Read good reviews for those and followed a recommendation of the assistant from Crutchfield. [ Yossi  Nov 24, 2017 ]
    Great deal and it matches the rest of my home theatre setup and furniture [ Juan Luis  Oct 20, 2017 ]
    On sale, good reviews and I've had good luck with Polk products. [ David  Oct 08, 2017 ]
    These speakers are highly rated with good reviews and are 40% off. [ SCOTT  Oct 06, 2017 ]
    Good Reviews for the past bunch of years. Saving $600 on the pair convinced me to see if they are better than my JBL L166's We'll see. [ Robert V.  Oct 06, 2017 ]
    I own the rti a7s already, love them and am upgrading. I would like to make sure that Zac gets credit for this sale as he was extremely helpful two weeks ago on the phone when I was making decisions. [ David  Oct 05, 2017 ]
    Quality of product [ Dan  Sep 22, 2017 ]
    Quality and power. [ Julie  Sep 20, 2017 ]
    I like the well balanced, warm and natural sound of Polk speakers. The Rti A9's are rated at 500 watts each and my amplifiers are rated at 450 watts each so it was a good match. The Rti A9's re well built and absolutly beautiful in the cherry. I have them crossed over at 60 Htz and they sound amazing. Give them plenty of power and they will shine!! [ Steven  Mar 16, 2017 ]
    reviews on your website [ w  Nov 12, 2016 ]
    Have been in the market for some nice powerful speakers for a while but haven't seen a 5-star average until now. Hope they don't disappoint! [ Eric  Jun 03, 2016 ]
    Read ALL of the reviews onlie at different websites. Also a co-worker has a pair of these. And....Polk has a great rep. I absolutly LOVE these speakers!!!! [ Friederika  May 27, 2016 ]
    I love Polk speakers. I have a pair of RTi A7 speakers as part of my home theater. For my Stereo setup I wanted something a little bigger, but with the same Polk sound. [ Laurie  May 08, 2016 ]

    There are a lot of brands and models that would work. I'm a Denon fan myself. Figure out what you need. You might not need an 11.2. Maybe a 9.2. Save a lot of money. 11.2 is the most expensive. Spend the money on quality cables and connectors. You will be glad you did.thanx! [ Duncan  Dec 09, 2017 ]
    I'm using a onkyo tx-rz900 [ Richard  Dec 09, 2017 ]
    I would highly recommend it. Maybe 2. That's what the 2 in 11.2 means. Why spend that kind of money on the receiver if you don't use its features? [ Duncan  Dec 09, 2017 ]
    If you're using this speaker for music 75% or more of the time, then no. If you're watching a fair number of movies, then I'd look for a sub with at least a 10 inch subwoofer. [ Kwang  Oct 28, 2015 ]
    No but I am not a subwoofer fan [ ZEV  Oct 17, 2015 ]
    That depends on how mauch bass you want. These speakers are very powerfull and have great Bass without losing the clarity. I feel when I'm watching a movie with surround sound, these speakers need a bass. But when your listening to music the bass these speakers have is enough. [ Daury  Oct 07, 2015 ]
    I don't think so. I listen to 70's and 80's rock, Pink Floyd, Zeppelin, etc. I also listen to more modern stuff like Saving Able, Theory of a Deadman, Hinder etc. and the bass is plenty for me. The vocals are incredible from these speakers. I'm using an older Yamaha HTR-5890 with the "B" speaker output bi-amping the woofers. I know, it's not a true bi-amp, but it sounds awesome! [ PAUL  Oct 07, 2015 ]
    Mark, I listen to Jazz and to classic 60-80 Rock. I do have a sealed Velodyne sub from my Magneplanar days but I find I rarely use it with the A9's. I power them with a pair of 250 watt mono blocks and they sound great. [ Robert  Oct 06, 2015 ]
    These are full range speakers, so you don't have to have one. I have these, but also use a subwoofer for theater sound. These are awesome speakers tho. [ JAMES  Oct 06, 2015 ] had alot of bass already, so i don't think you need one [ Khanh  Oct 06, 2015 ]
    We do have the Polk Audio HTS10 (Brown) powered subwoofer cataloged in our inventory database; meaning we will eventually be carrying it here. However, I'm afraid we're still waiting for Polk to give us an official ETA for when we'll have them in stock. Like Steven alluded to in his response above, Polk's website has a release date posted for "October 2017" so hopefully we'll have more info on that soon. Please feel free to check back with us periodically for any future ETA updates--you can contact an Advisor directly by phone at 888.955.6000 or online chat. Thanks! [ Larry  Oct 04, 2017 ]  Staff
    Polk's website has a tentative release date of late Octorber. My guess would be that it's hard to say what the turn around time is for Crutchfield to get it up and available on their website IF they are even going to offer it. Hope this helps. [ Steven  Sep 30, 2017 ]
    Dont think it's necessary, but these speakers like to be pushed so I would [ LEONARD  May 27, 2016 ]
    I will not be able to answer that question because I have them paired with a Marantz. [ Phillip  Mar 29, 2016 ]
