Potent bookshelf speakers

Treat yourself to detailed, accurate sound with Polk's compact RTi A1 bookshelf speakers. They feature Polk's exclusive Dynamic Balance® drivers for smooth accurate response. Plus the woofers and tweeters undergo careful laser testing to help identify and eliminate unwanted resonances that can hinder a speaker's performance.

RTi A system

Thoughtful cabinet design

Cabinet cross-section

The asymmetric cabinet helps fight vibration for clearer sound.

The RTi A1's newly designed asymmetric cabinets help them deliver rich, clear sound by combating vibration and increasing rigidity. You'll enjoy remarkably clean mids and highs for a well-defined soundstage, along with tight bass. Plus, the cabinet's curved edges give the speaker a polished look, enhanced by a real wood veneer finish.

Great for home theater or stereo music setups

The RTi A1s do a great job with stereo music on their own, or you can team them with a powered subwoofer for even better bass. Or use two pairs as your home theater's front and surround speakers for dynamic, detailed movie sound. For larger rooms, the RTi A1s work perfectly as surrounds in combination with RTi tower front speakers.

Recommended center channel speaker: Polk CSi A4.
Recommended surround speakers: Polk RTi A1.

    Why choose bookshelf speakers?

    Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

    Great Bookshelf Speaker

    Written by: Stanley S from New York on January 4, 2016

    Crutchfield Customer Review (What's this?)

    The Polk RTi A1 is an outstanding speaker which delivers clear uncolored sound and is perfect for a medium sized room in apartment living. It is also perfect for classical music and there is no need for a sub woofer to expand the bass.

    Pros: Good clean sound. Very nice construction and it looks good in a living room setting

    Cons: none

    Great Bookshelf Value!

    Written by: Jerry S from Illinois on December 22, 2015

    I have had these speakers for over a year in a few smaller rooms, such as a bedroom and dorm. Let me say, for smaller rooms, these speakers are fantastic. Not only is the sound good, but the cherry veneer I have on my looks great. Right now I have them paired with a Polk PSW110 sub woofer for better bass extension, and the combo is perfect for the size room they are in. Great for both movies and music! I would highly recommend these if you are looking for a well rounded bookshelf that you can fit most places.

    Pros: Good bright sound Solid construction Beautiful wood Bi-wire / Bi-amp design with solid binding posts Great sound for your money

    Cons: Lacks bass extension; easily fixed with addition of sub

    Crutchfield Customer Review (What's this?)

    I have 7.1 surround with RTi A speakers and purchased these RTi A1's for front height speakers. Now it is nice to have 7.1.2 surround for Dolby Atmos with timber matched speakers. These will only get better when they are broken in. Great for movies & Music too. San Andreas sounded awesome with these in Dolby Atmos.

    Pros: Great sound & a good value. Glad I'm using them in my Front room & Bedroom systems.

    Cons: Wish I could comfortably afford the Polk LSi M series for both rooms. These RTi A's make me curious.

    They just don't get any better. The sound is crisp clean and deep. The build quality is excellent and they are beautiful to look at. They sound like a much larger speaker.

    Pros: Sound for size. Appearance. Build quality. Price

    Cons: None

    The Polks are a bargain !

    Written by: Mike from Pennsylvania on June 20, 2015

    The Bass is full and punchy with excellent upper bass fullness satisfying detail and tunefulness. The punchiness is such that in my bedroom that is relatively small it sounds like a much bigger speaker throwing a large image with good depth. The punchiness and impact fills the bottom end so much a find a subwoofer not necessary. Most small speakers lack dynamics and sound a bit compressed and lacking excitement to me but not these Polks, they are surprisingly dynamic for the size and don't require turning up the volume to get the punch and dynamics. The midrange is full detailed and surprisingly transparent for such an inexpensive speaker. The top end integrates well and is detailed and clean with a thickness you wouldn't expect. High frequencies in this price range usually small no matter the size of the image to my ears. I just wish it had more high frequency energy for those of us with sofas rugs and other things to absorb those frequencies and if we wanted less we could just put the grills on but I could say this about most speakers. With the grills off I get just enough high frequencies. It's very efficient and I don't think Polk fudged on those specs because with my modest Nuforce DDA-120 it sounds powerful. I only paid 225.00pr. for this on sale at crutchfield and its got veneer. My Paradigm Signature S1 speakers sound only slightly more transparent but cost 4 times the price and needs a subwoofer. The Polks are a bargain even not on sale.

    Pros: Great soundstage good transparency, veneer , Incredible Bass for a small speaker you may not need a subwoofer.

    Cons: Could use a bit more top end for some.

    Crutchfield Customer Review (What's this?)

    I spent a considerable amount of time online comparing options for bookshelf speakers. With this being my first quality speaker purchase, I couldn't be happier with these Polk's. For the price, the sound is tremendous. Fills the room with crisp, clear sound. I have it paired with my Onkyo stereo and Audio Technical turntable. To make it even better, these speakers are especially aesthetically pleasing.

    Pros: Crisp, clear sound. Good look. Easy setup.

    Cons: none

    Excellent speakers, especially for the price

    Crutchfield Customer Review (What's this?)

    These speakers, while not super strong on the low-end (you can't expect that with 5.25s) have excellent clarity and depth of field. I set these up in a 5.0 set-up (sub is on the way) and it works excellent with music and movies. Especially when at $225, cannot complain.

    Pros: Clarity, Sound field, Price

    Cons: Low-End Strength

    Crutchfield Customer Review (What's this?)

    I've recently upgraded my home theater system and went with Polk audio for my front floor standing speakers (RTi A7's) surround speakers (RTi A1's) and rear surround (TL2's) my wife actually commented on how much better they sound and trust me this is nothing short of a miracle since she really has no interest whatsoever in audio equipment, specs or brands. I on the other hand I am a musician and have done studio session work as an artist and producer so I my ear is much more refined and I've learned to listen and look for certain things when it comes to spec's and audio reproduction.IMHO these Polk audio RTi A1's are the best buy for your money ( trust me I do the research before buying anything) they have full rich dynamic response and provide a clear accurate reproduction of your source material weather its music or home theater definitely a 5 star product

    Pros: size, versatility, sound and cost

    Cons: none

    The RTi A1 speakers were the perfect fit for my front speaker location, and look great in the cherry finish. Sound and high quality build are as I expected from Polk Audio. They completed my 7.1 system and added the mid range that I was missing. Crutchfield was perfect as always. Highly recommended.

    Pros: Great open sound. Quality cabinet and finish.

    A Beautiful Piece of Equipment

    Written by: John Barrow from Texas on March 18, 2015

    Crutchfield Customer Review (What's this?)

    I am not a professional musician and bought this speaker set on the advice of the Crutchfield representative. It arrived in perfect shape, even though UPS mistakenly sent it through much of Texas before getting it to my location. I have set it up and the it produces a great and vibrant sound. What really impressed me is how sturdy and beautiful this piece of equipment is. I bought the cherry wood model and it is a really striking addition to my new weekend home. Thank you Crutchfield for the recommendation. I also bought Polk outdoor speakers, but have not hooked them up yet. I will review those when I do, but based on the quality of the RT1A1, I am optimistic they will be of top quality also.

    Pros: Great sound Sturdy, well-made speakers Absolutely beautiful finish Great price

    Cons: None

    Crutchfield Customer Review (What's this?)

    I purchased three sets to accompany Polk's matching center channel (CSi A4) for my 7.1 system. Recommended. I've ordered Polk's DSW PRO 550wi sub to round out the system.

    Pros: Timbre matched, solid construction, ascetically pleasing. A bracket, screw and template is provided to make side- and/or back-wall mounting a snap.

    Cons: None.

    I am using these as the "main" speakers in my office, connected to a PC. I watch a lot of movies and listen to a lot of music in my office. These speakers do the job. I have only had them for a few days, but they are lively and clean. I am using them with some BIC Venturi surrounds and center and an Energy ESW-M8 subwoofer. These speakers are clear and clean. I got them on sale. From a value perspective, they are amazing.



    Big Room Problem Solved

    Written by: RobA from Iowa on May 5, 2014

    Crutchfield Customer Review (What's this?)

    After years living in a house with fairly standard rooms my wife finally got her "open concept" home. I call the main floor the cave. It's two stories of sound killing wood and walls. I have spent the past three years trying to put together a system for viewing movies and listening to music so that I can hear dialogue while watching TV and then enjoy music when the TV is off. Last year I bought some Polk Audio in wall speakers for the rear of the system and this year I purchased these RTiA1 speakers for the front surrounds. The speakers solved my big room sound problems without having to go to the mat with my wife over larger speakers. The dialogue is crisp and clear, and now I have no problem hearing my favorite TV shows and movies. The speakers also give great wide range sound when listen to music. An added bonus are the maple wood enclosures that actually match the credenza that the whole thing sits on. I am really satisfied with both the rear in wall speakers and my new RTi fronts.



    Very Discouraging

    Written by: GlennE from Gretna, LA on February 18, 2014

    Bought these after searching, reviewing, pricing and deciding not to rebuild my 20 year old Infinity's. Right out of the box, one of the woofers didn't work. Customer service said they would replace them. Just very disappointed thinking Polk was a solid product. :{

    Pros: The one speaker that worked sounded pretty good.

    Cons: Having to box up and ship back and wonder if I made the right decision.

    I use them as front speakers in my home theater set up. For my room size these are really good. The bass response in these puppies is unbelievable for their size, they compliment the PSW 125 subwoofer and the Tsi CS 10 that I am using for the center speaker.

    Pros: Small, and Oh so strong.

    Cons: None

    Beautiful addition to my home The cherry finish is excellent. The construction of the speakers exceeded my expectations as did the sound. I also use a powered sub woofer and the two together are just perfect. The overall tonal range is exceptional and solid sounding. I have not done so as yet, but I do plan on mounting these speakers on the wall. I have already recommended them to a friend. Great purchase!

    Pros: Beautiful construction, shielded, wall mount capability

    Cons: I have nothing negative to say about these speakers.

    Great sound from a small package

    Written by: Tigertomc1965 from Kunkletown, PA on October 6, 2013

    Crutchfield Customer Review (What's this?)

    This small bookshelf really performs well. I have a setup of RTi A3 for fronts, a CSi A6 and now these as my surrounds. This is a great setup. All of these Polk speakers are very high end in build quality. They look great and sound even better. I was concerned about size but these do not disappoint. I get plenty of sound to fill my room. They tend to be really bright speakers. So mids and highs are there in quantity. With my system I had to turn down the highs 10db and the mids 5 db and then pump up my bass 5-10 db and it now sounds amazing. Even these speakers give me the thump, thump, thump when the bass is high. I do not have the crossover set very high (at 60hz) but these provide good bass sound now that the highs and mids are muted some with my setup. I still get amazing clarity and distinction between instruments so no muddy sounds here. I am thoroughly impressed. Wonderful investment. My only complaint is with Crutchfield's ability to take their speakers off sale just before I wanted to buy them. If you buy some of the set at one time then do not wait for your points or the rest of the set will be off sale when you actually have the points to use.

    Pros: Sound great, great distinction between instruments, small size, good bass sounds from a small package, great quality, looks great in my room.

    Cons: expensive, very bright but can be adjusted.

    Crutchfield Customer Review (What's this?)

    I spent weeks evaluating these speakers and when I was ready to purchase, I chose Crutchfield because of thier good service, advice, and price. I already have Polk Audio speakers installed in two other zones and needed new fronts in my main 5.1 zone (TV room). My Onkyo "head end" has never sounded so good! Thanks Polk Audio and Crutchfield for partnering to provide excellent sound in my main zone.

    Pros: Great soundstage and integration with existing system. Balanced highs and lows that reproduce great music and audio in home theater. Beautiful cabinets and look almost as good as they sound!

    Cons: None to mention.

    Pros: Upgraded my 2.1 home theater to Polk´s RTi A1 speakers, very precise, "warm" sounding set. Great value for the money, solid construction; the natural Wood finish complements the bookshelf. Overall I conclude recommended...

    Cons: Had them shipped next day air oops, cost was steep. This is why I rated 4 out of 5. Suggest use free shipping for speakers! To balance, Crutchfield shipping, like clock work.

    Just set these speakers up in a 27' x 14' room. I installed them with bookshelf hangers from Sanus . I installed these at ceiling height but was able to tip the speaker down to direct it into the listening area. I also matched these up with a CSI A4 center channel located at ear level under the big screen television. These speakers are powered by an Onkyo HT-RC260. Hidden is a powered subwoofer. Rear speakers are Bose. This system rocks. So much dimension you swear your in the middle of the action. Clear, Clean, undistorted sound.

    Pros: Great looking! Nice speaker connections.

    Running the A1s off a Denon AV-1913 on shelves in a large room. Was worried about filling the whole room, but worry no more. I use for TV, movies, Blu-Ray, Pandora, iTunes AirPlay, etc. These babies definitely do the job, along with the subwoofer and in-ceiling Polk MC60s...great sound field.

    As mentioned in other reviews, the A1s are bigger than they appear, especially in depth. Something to be aware of. Can certainly re-allocate to the back as surround speakers given further upgrade in the future.

    Crutchfield Customer Review (What's this?)

    first picked up the CSi center by Polk, my Energy Take system was infuriating when it came to dialogue with some movies. and wouldn't you know it, they're right when they say you need to voice match your fronts with your center. the energy Take fronts didnt quite mesh with the Polk center. picked up the voice matched RTi A1s 2 weeks after the center. the sound is insanely sweet. dialogue is crisp. with the Energy Take system, there was no need to ever go to the movies. now there's no need to go to work either.

    Need break in

    Written by: Mike D from Twin Cities, MN on February 13, 2013

    Crutchfield Customer Review (What's this?)

    Several people have commented that you need to give these speakers time to break in and I agree. Out of the box I was immediately impressed with the quality and the beauty of the Cherry cabinets. When I heard them at first I thought they were shallow and muted in a way. After 10-15 hours of running them they have improved and gotten much crisper and I definitely am impressed. On their own, they don't have enough bass for hard rock, but they perform well on their own with other "softer" genres that don't require pounding bass. I have them paired with JBL Northridge Series towers and JBL Northridge Series sub in a very large open space and they really fill-in the mid-range and highs.. Maybe the A3's would have been better considering the huge room they are in, but that is not a knock on the speakers as much as it is my application for a bookshelf.

    Pros: Beautiful cabinets. Nice sound. Excellent wall mount system.

    Cons: On their own they are not enough for a big room or really heavy music. Maybe the bass ports would be more functional if mounted on the wall.

    Attractive bookshelf unit. Two pairs of wire attachments is good for attaching multiple sources. Sound quality is ok, but a bit Tunney. I have a lot of Polk speakers. Not sure these measure up, but I'm probably being a bit hard on the small base.

    Crutchfield Customer Review (What's this?)

    Once again, Polk doesn't dissappoint. I've been a Polk fan for years, so excuse the bias. If you're familiar with Polk then this review will sound familiar as well. If you're not a fan then you owe it to yourself to give these speakers a listen. Open mids and highs and surprisingly decent bass. My receiver actually thought they were "large" speakers when I ran the microphone aided auto set up (Pioneer VSX 1020). When set up properly, they produce an open, natural image. I have these mated with a CSi A4 center and DSW 550wi sub, which I purchased as a set, due to the current special with the sub discount along with some older T15's that still do well as surrounds. Check the measurements on the CSi A6 center before deciding on that vs the A4. Neither is small, but the A6 is huge, and to be honest, the A4 is impressive in an average sized room (mine is 17' x 22' and the A4 doesn't lack for anything when mated with a powered sub). Just watched Transformers D.O.T.M. after finishing receiver tuning and all I can say is WOW! Great dynamic range with 0 distortion. Music lovers don't worry...these have you covered. Not only did they make Pandora's sound quality level up considerably (not an easy task...), but well recorded CD's sound sublime, with details you probably have been missing. I've auditioned everything from Bose (you're paying for the name...) to Def Tech to Paradigm and Revell. You have to spend a LOT more to beat the RTi series...

    Pros: Open, natural sound, with great dynamic range. Suitable for movies AND music.

    Cons: They're not free...

    I have these sitting on a hardwood floor on my second floor office. All I can say is they sound really good. The bass is nice and tight without causing unnecessary vibration. Everything I have played through them has sounded better then I would have imagined (From Gershwin to Madonna to Iron Maiden). The price can't be beaten either.

    Pros: Fit and finish, sound, and price

    Cons: None so far.

    Pros: Good value for money, well made

    Cons: A little weak at high volume, but for bookshelf units this shouldn't be an issue

    I had a cheap "R.S.? center speaker" blow on me when I hooked up my Yamaha audio reciever, so I first ordered the Polk CS20 and found I had to replace my right and left front speakers as well. I opted for the RTiA1's and the sound is explosive. When my R.S. powered subwoofer goes I will be back for a Polk powered subwoofer.

I mainly listen to acoustic and electric jazz at low - moderate volumes. Even pushed by a 20 old 55W/channel receiver, these things sound amazing. For the price -looks and sound are impossible to beat. Impressed so much I await the arrival of RTiA3's which will replace old floor (no name) speakers. Also ordered a NAD C356DAC amp to run both of these speakers and am looking forward to the major upgrade in that as well.

    Thanks so much Crutchfield for offering a diverse inventory to select from for people who like to listen to music and not HT. No brick and mortar store exists around me any longer that provides a 2 channel music listener such a selection. It seems everyone has migrated to home theater or car audio.

    Pros: Sound, looks, price.

    Cons: None.

    Great Surround Sound Speakers

    Crutchfield Customer Review (What's this?)

    Bought these in conjunction with Polk TSi 400's and Polk TSi CS10's to replace my Bose Acumass 10 system. These speakers sound and look great in the cherry color. Although I'm using them as surround sound speakers they are also probably adequate as front speakers with the stands I purchased. I was hoping that with the woofers contained in all these speakers a powered sub-woofer would not be necessary. But if you want the true "theater" sound you need the sub-woofer which I bought at a later date. Strongly recommend these speakers.

    Awesome set of bookshelf speakers that have been used for home theater fronts, surrounds and also living room 2 channel stereo system. Very solid construction, excellent build quality, superb performance. Tested Bose, Infinity, Pioneer and Polk came up the winner in this category and price range. Would buy them again in a heartbeat. Effectively no distortion and highest volumes I can handle.



    nice stand mount speakers

    Crutchfield Customer Review (What's this?)

    I bought these speakers to use with a Peachtree Decco 2. I have owned them roughly two months now and have been really pleased with the combination. The upper frequencies and the midrange are clear and life like. There is a surprising amount of low frequency output for its size, but, depending on the recording, there are times I wish I could get a little more support for string bass and the like. I had the larger Rti A1s for a few weeks before I sent them back for these. The RTi A1s had a fuller lower midrange, but there were times that they seemed tto sacrifice upper midrange accuracy for lower bass extension.
    One last consideration---these speakers will really sing with good power and a musical signal. I hooked these up to a Yamaha surround receiver and it revealed all of the receiver's inaccuracies. Hooked them back up to the Decco 2 and got a much more musical sound. I wish I could hear these Polks with a Peachtree Nova which has more power. Might be even better than they are.
    Aesthetically, these are very attractive speakers sitting on some 24" stands.



    Great sound for a good price

    Written by: Mike from NJ on November 27, 2010

    I have had these speakers for, about 2 years now and I am very impressed with the high frequency detail and the very rich mid range frequency. The lows are there and very powerful for a bookshelf speaker. I had originally hooked the RTi A1s to my old 30 year old stereo. I heard detail but most of the time the highs were grainy and the lows muddy. But after i bought a NAD C355BEE from Crutchfield, i then heard what the RTi A1s had to offer. The detail and the liquid sound is amazing! No grain or muddy bass. I give credit to both the NAD C355BEE and the Polk RTi A1s, the two make a great pair. Both are worth every dollar$!!!



    Polk Audio RTi A1

    Written by: Kelly from Alachua, FL on February 10, 2010

    Overall these are very nice speakers. I am currently using them as a stereo set and they work well even without a subwoofer. Quality of sound seems to depend on quality of the broadcast and/or input media. Adding to the speakers to make a 2.1 or 5.1 system would most probably improve the output as well. However, these speakers produce a robust sound with very articulate voices and rich music on their own.



    Polk Audio RTi A1

    Crutchfield Customer Review (What's this?)

    I got the Polk RTiA1 speakers because of a recommendation. I was told they would provide a clean and natural sound. To an extent they did, but there were some issues.

    I compared the RTiA1 to the Boston Acoustics CS26 and my Thiel CS0.5 and Boston Acoustics CR77 speakers. I used a stereo setup to evaluate them.

    Out of the box the RTiA1 speakers had a beautiful, though a tad dark, real natural cherry exterior. I have natural cherry living room furniture. They fit in well. They also seemed to be solidly built.

    Well it really all comes down to how they sound. The RTiA1 highs were clear and just a tiny bit subdued. Vocals were where the problem came in. There seemed to a small amount a distortion in the lower end of the vocals. Since this was at the lower end, it wasn't noticeable with female vocalists. It was noticeable with male vocalists. It wasn't a big deal, but it was there. Also the vocals were a tad recessed. The bass was clean, clear and well defined.

    There are slightly warm speakers, much like my Thiels, to which they compared pretty well. They weren't at the same level as the Thiels, but that's to be expected at this price range. The Boston Acoustics CS26 and CR77 speakers were both more livelily and the vocals were more forward then with the RTiA1s. That being said, the CS26s couldn't match RTiA1s in warmth, imaging ability or clarity.



    Best bookshelf under $500

    Written by: Mike from Hamilton, New Jersey on September 29, 2009

    The RTi A3 has to be one of the best values for under $500. The articulation and transparency of these speakers is nothing short of outstanding. If you listen to classical music you will be amazed as every nuance is captured. My collection of CD's includes Steely Dan's Aja, and Chicago's Chicago Transit Authority, both sound incredible! If you are looking for what might be the best bookshelf speaker for under $500, look no further.



    Polk RTi-A1 = Best sounding speaker under $200 !

    Written by: John M from ABQ, NM. on March 25, 2009

    WOW ! Built my HomeTheater with these as my front main L/R speakers. Teamed with Polk Audio's RM6752 Center, RM6751's for Rear Surround, and a PSW-10 Sub. These are being fed signals from a PS3 into a Yamaha RX-V463 via HDMI. Have the RTi-A1's mounted out one foot to the side of a 46in LCD HDTV mounted on the wall of my small, stone floor livingroom. The sound of this System is OUTSTANDING ! The performance of the RTi-A1 speakers are SPECTACULAR ! I am completly sold on Polk Audio Speakers, Yamaha Receivers, Sony PS3 (Blu Ray), HDMI Connections, and Crutchfield ! This setup, minus TV was a tad under $2K, and sounds as good or even better then my Nieghbor's "HighDollar" Amp/ A/V Pre-Amp w/ Klipsch $$ Speakers all around ! When my house is "on".. cars stop to listen !

    This is a great speaker for the front of my home theater. The sound is clear and full. It blends in perfectly with my other Polk speakers.



    Compact and Powerful

    Written by: Lee90125 from Ridgeland, MS on February 13, 2009

    Crutchfield Customer Review (What's this?)

    I recently came into enough cash to buy my first true home theater. I must say that after spending months agonizing over which components to get, that my decision to buy this pair was the right one. Things I took into consideration when choosing this pair were, size, power handling, reviews on this and various other sites, finish, utilization of front air ports and cost. I have yet to find a negative review of these speakers and the footprint they use is tiny, which fits my semi-minimalist tastes.

    I am currently using them as my front left and right channels, pumping 100w though a new Denon HD Receiver and they do not disappoint. They have had two months to break in and provide excellent clarity for music, movies and really shine with HD Audio. I look forward to having these for many years and when the space allows, I plan on using them to flesh out my system to a full 7.1 surround.



    Great Little Speakers

    Crutchfield Customer Review (What's this?)

    I am only using these as surrounds in my system and as part of an overall
    speaker upgrade to RTi speakers. They perform very well and I am sure
    would be more than capable of doing much more than I call upon them to
    do. The sound is rich and clear. The fit and finish is absolutely excellent.
    Polk makes fantastic products and Crutchfield is a class act to do business
    with. I am totally sold on both.



    Polk Audio RTi A1

    Written by: Joe from USA on September 29, 2008

    Crutchfield Customer Review (What's this?)

    After about 100 hours of use (mainly for listening music in stereo), the sound from these speakers is becoming extremely very real life. It improves with time. We are using a power amplifier instead of a receiver to get better sound. For TERRIFIC TERRIFIC AM/FM audio reception and sound we use a little Tivoli Pal radio to feed the amplifier (optional RCA-Miniplug cable required). Also you have to spend time to fine tune some details such as space between speakers, distance from walls and speakers height level.

    Thanks crutchfield!

    Sounds beautiful. Use these in my bedroom, 5.1 system with RTi A3 up front, RTi A1 surround, CSi A4 center and a PS10 sub. Sony receiver. Love it. These can take power and sound good with U2 or Stevie Ray Vaugn at high volume. Wife loves em too but she cant take the volume. Ya know I dont see her as much as I used to, hmmmm?



    Solid Performance in a 7.1 system

    Written by: Larry from Cincinnati, Ohio on April 28, 2008

    Crutchfield Customer Review (What's this?)

    I am replacing an 18-year-old 5.1 system and decided to upgrade to a
    7.1 system. Wow, what a nice sounding product that is beautiful to look at.
    As more and more 7.1 movies are released on Blu-ray, these speakers will
    be used as the back surrounds in our home theater room (TR).

    I have a dedicated 2,850 cubic foot TR and added a complete 7.0 system
    from Polk (I already had a new 12" 350WRMS Sub). A tower speaker was
    ruled out due to the WAF (Wife Appreciation Factor) and the built in 15'
    wide entertainment center. I paired these speakers with the RTiA3 front
    speakers, FXiA6 surround speakers and CSiA6 center speaker. The sound
    field produced is amazing for clarity and balance and with a proper AVR &
    HD player; the Wife & I are never going to the Cinema again!

    Whether you are watching a concert HD Disc or Hollywood movie, the
    sound is so accurate and believable to what you are watching. These
    speakers produce an experience with sound that I have never heard
    before. The Sub takes care of the LFE and that allows the rest of system to
    work the mids and highs to perfection. The sound is warm, inviting and
    immerses the listener. I can now listen to HD movies at higher SPL without
    any discomfort (at certain frequencies) that bothered me with the old
    system. This system will easily support me for another 18 years (Sorry



    Good little speaker with 'pluck'

    Written by: Ken from Maplewood, NJ on April 14, 2008

    Crutchfield Customer Review (What's this?)

    The A1 is a very
    good little speaker.
    I purchased these
    to replace a
    relatively new pair
    of Polk Monitor 40s
    which I liked a lot
    but were larger than
    I wanted. In my
    view the A1's sound
    at least as good as
    the 40's, better
    perhaps, and are
    much smaller with,
    again in my view, a
    vastly superior
    cosmetic appearance,
    the cherry veneer is
    very nice.

    In comparison to the
    larger A3s the A1s
    are very nearly
    identical with
    respect to sound
    quality in my view.
    I had hopped hat
    the A3 would be a
    great step up from
    the A1 based on my
    experience with the
    CSi A6 versus the
    CSi A3 center
    channel, but this
    was not my
    experience. Please
    see my comments re
    the Polk CSi A6's.
    Yes the A3s are
    larger and have
    'more' sound, but to
    my ear, testing in
    my main room with
    my gear, the
    difference was not
    that substantial,
    perhaps the A3s were
    a bit more open, but
    this is really a
    touch call. Every
    time I would listen
    to the A3 and think
    they were better I
    would swap in the
    A1s and not be so
    sure. In the end,
    given my inability
    to observe a
    improvement in the
    A3s over the A1s,
    the smaller size was
    the deciding factor
    for my HT
    especially given the
    fact that the HT has
    a sub so the
    marginal extension
    of the A3 is largely
    redundant /

    Hope this helps,
    Crutchfield is
    great, would not buy
    anything they carry
    from anyone else.

    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: Each speaker features a 5-1/4" polymer composite woofer for smooth wide-range response with low distortion. For high performance durability, each woofer uses a butyl rubber surround.

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

    Frequency Response: The overall frequency response is 50Hz-27kHz and the -3dB frequency response is 60-26kHz.

    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: Each speaker has a rear-firing Power Port venting system built into its back plate for precise deep bass response. This venting system allows air velocity to slow gradually, vastly reducing air turbulence, and delivering greater bass efficiency than conventional ports.

    Acoustic Resonance Control (ARC): Internal cabinet resonance can impart a "thick" character to voices. Polk's patented Acoustic Resonance Control port system overcomes this problem. In addition to the Power Port venting system, each speaker has a front-firing port that is tuned to suppress the internal cabinet resonance, resulting in smooth, natural midrange reproduction.

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


    Dual 5-Way Binding Posts: Each 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.

    Mounting Options

    Wall Mounting: The Power Port back plate on each speaker has a keyhole slot, allowing the speaker to be mounted on the wall using the supplied 2-1/2" wood screws.

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

    Crutchfield asked  
    Why did you buy this?

    Had Infinity speakers in our house that we lost in a wildfire, Time for a upgrade on replacement. [ Eric  Jan 20, 2016 ]

    2 questions already asked

    If the subwoofer has a line input (RCA or Mini) then you should be able to connect it to the receiver. Either directly using the subwoofer level output and line-in or with an adapter from the RCA level output of the receiver to the mini jack in on the subwoofer (again depending on the input). If the subwoofer does not have a line input then it will not work with the receiver. [ Jeff  Mar 19, 2015 ]  Staff
    I feel it's very much an awesome value. I power these speakers (wall mounted) w onkyo tx-8050. My space is a 900 square foot bottle shop. We run internet radio and play vinyl daily. RTi A1 's sound awesome bass without a sub. For our purposes, perfect. Sometimes we have upwards of 40 ppl in that small space and they still deliver. hope this helps. PC [ PHILLIP  Sep 09, 2014 ]
    Is RMS or "root mean (average) square value. The rule is that Max or Peak values are are clearly stated in any equipment specs. There is One Peak value not a range of Peak Values. The RTi's are very efficient speakers so they can work well with a low power amp as low a 20 watt in the connected channel. They can work in a high power channel up to 125 watts as well. 125 is the maximum RMS watts recommended for the speakers. It seems these speakers were well tested at different power supplies for a certain time period. I am using then with a Denon AV-E400 185 Max output watts/channel (90 watts RMS/Channel). Sounds great. If 20 t0 125 were peak values, (there can only be ONE peak value) they could'nt hold 90 watts RMS. Hope this can help. [ ANIBAL  Sep 05, 2014 ]
