Our take on the Polk Audio TSi400

by Loren Barstow
Polk Audio

Floor-standing speakers — still standing tall

Sure, floor-standing tower speakers buck the industry trend toward smaller, visually inconspicuous speakers, but they're hard to beat if great sound is your primary goal. Tower speakers produce powerful sound with excellent bass, making them a great choice for serious music lovers and for folks who want high-impact home theater.

Whether you're looking for speakers for your stereo music system or seeking out new front speakers for your home theater, you can count on the Polk TSi400 for clean, engaging sound. Its silk tweeter delivers sparkling highs, while three polycarbonate woofers churn out accurate mids and lows. The well-braced cabinet fights resonance so the details in your music and movies shine through. Dual five-way binding posts let you bi-amp or bi-wire the TSi400 for even better performance — a rare feature for a speaker in this price range.

A woodgrain vinyl finish gives the TSi400 a refined looked, capped by an elegant piano black top plate. At the base of the speaker you'll find sturdy stabilizer feet to keep it anchored to your floor, regardless of whether it's carpeted or non-carpeted. And since the speaker's footprint takes up less than one square foot, you can enjoy high-impact tower speaker sound without sacrificing a lot of space.

    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.

    Klippel Optimized: Using a state-of-the-art Klippel Distortion Analyzer, Polk engineers were able to optimize the speaker structure and cabinet design for the best possible performance, even at extreme listening levels.

    High Efficiency Design: Compatible with practically any AV receiver, these speakers produce sound that is open, spacious and clear, even when driven by modestly-powered amplifiers and receivers.

    Bi-Laminate Composite Woofers: The speaker features three 5.25" bi-laminate composite dynamic balance drivers which are light and stiff for deep bass response and low distortion. The multiple smaller driver configuration is capable of better detail than one single large woofer. This design also projects sound over a wider area, so there is a broader sweet-spot. For high performance durability, each woofer uses a butyl rubber surround.

    Silk dome Tweeters: The speaker features a 1.0" silk dome dynamic balance tweeter for detailed highs. The tweeter features mylar bypass capacitors in the crossovers to extend high frequency response and improve detail and transparency.

    Frequency Response: The overall frequency response is 34Hz-25kHz and the -3dB frequency response is 44-24kHz.

    Enclosure Design

    Quality Built Cabinets: The TSi speaker cabinets are extensively braced MDF with ¾" thick baffles. With pewter accents, a piano black top plate and removable black grille, TSi speakers look awesome and take up less than one square foot. All models are available in a choice of black or cherry wood-grain vinyl finishes.

    Narrow Baffle Geometry: Narrow baffle geometry is a design that creates a sleek looking speaker with great sound. The high quality cabinet is slender and tucks away easily in your room. The smaller-diameter speaker components are lighter in mass, translating to clearer sound.

    Flared Ports: All TSi speakers feature critically-tuned flared ports. Flared ports minimize port noise ("chuffing") and ensure good low frequency extension with low distortion. With flared ports, TSi speakers reveal realistic, natural, full-bodied sound with rich bass. These TSi floorstanding speakers feature a down-firing power port.

    Connections

    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.

    Mounting Options

    Placement: Create an equilateral triangle between the speaker and the listening position. If you notice video distortion or discoloration, immediately move the speaker away from the video source.

    Built-In Conical Feet: The speaker features four built-in conical feet to ensure stability for precise bass response and superior imaging.

    Crutchfield Customer Review (What's this?)
     
    Had to get things set with my receiver but once I did the sound is great and works well with my other Polk Speakers ie sub etc. The size of the speakers are great and they deliver great for the fairly large room size. Also works and sounds great with my audio-video set up.
    Pros:
    Size and looks as well as great sound
    Cons:
    I have none at this point

    Exactly what I wanted.

    Written By RyanG, North Carolina on Sunday, June 29, 2014
    Crutchfield Customer Review (What's this?)
     
    These speakers are handsome, priced reasonably, sized nicely, and they produce great sound. I was really impressed with the amount of bass they put out. I tried a subwoofer with the system, but in the end felt I didn't need it because the speakers were producing such full sound on their own. Granted, I am mostly listening to music on my system and am not trying to amplify low frequency effects in movies. I also am using these speakers in a large bedroom. I am sure they will work just fine in a living room as well, because I have come nowhere near close to pushing their limits. I paired them with a Yamaha home theater receiver and use Monster XP cable with Monster screw-on banana plugs.
    Pros:
    Looks, size, and sound.
    Cons:
    None that I know of.

    Big bang for your hard earned bucks

    Written By Rick C, Hammonton, NJ on Thursday, April 10, 2014
    Crutchfield Customer Review (What's this?)
     
    These speakers replace an older pair of Wharfedale Emerald 97 that sounded beautifully. The Polk sound crisper, cleaner, and more accurate. My fear was the price was not parallel to its quality. Price generally indicates quality level. The reduced price made the value ratio superior to expected. In other words I have speakers worth double the money spent.

    When added to my Elite sc-65, and a Mirage plus A Klipsch second sub with bi-directional Fluance rears, my entertainment room sounds fantastic. These towers are the Keystone of it all. To add above all else, again, is the tremendous value. I have the speakers bi-amped which may be overkill. But I love what I now have. These Polk may not be B&W, or Martin Logan, however you would have to be an engineer to differentiate them.
    Pros:
    Crisp, clear, and powerful
    Cons:
    I have non at this point.

    Polk TSi 400 Speakers

    Written By MCA, Laramie, Wyoming on Sunday, March 23, 2014
    Crutchfield Customer Review (What's this?)
     
    These mid range speakers are perfect if you have limited space and are looking, or listening, for great sound. For the price of two, less than $500.00, these are a steal! I would highly recommend these speakers for someone on a budget or beginning to build a nice system. Match these with the others in the TSi line and the sound is even better.

    Polk Audio speakers

    Written By don fisk, SHERIDAN on Wednesday, March 12, 2014
    Crutchfield Customer Review (What's this?)
     
    I had to rely upon the advice of a Crutchfield rep. to select my speakers. I was unsure about the difference between the TSI400 and the TSI 300. I don't know how these would compare to the 300s, but I am very pleased with these! I think they are a great value for the price and suit my needs perfectly.
    Pros:
    Sound, price, styling, ease of connection.
    Cons:
    Haven't found any yet.

    Polk Audio TSi400

    Written By Anonymous, Northern michigan on Sunday, February 02, 2014
    Crutchfield Customer Review (What's this?)
     
    Im certainly no audiophile for sure, just a music lover, but i love these speakers. The sound is crisp and extremely clear in my living room. I love it. My system has a subwoofer, but even without it the 400's delivered a solid lower end. Far better than any other significantly under 300$ speaker ive heard. Easy to work with, they aren't heavy and have good quality posts that are easily accessible. They're also nice looking, and dont take up much space. What makes them sweet is how narrow they are. You can squeeze them in anywhere without a problem.

    Good, clean sound

    Written By Byrdman, Montgomery, AL on Friday, January 17, 2014
    Crutchfield Customer Review (What's this?)
     
    Before choosing the TSi400, I read ALL 51 of the reviews. Many said the low-end was lacking, but that was not an issue for me since I have a PSW125. When they came in, I hooked them up and set them to my home theater with 5.1 surround. Did not have to make any adjustments probably because they were replacing my worn out RTi100s. I thought I may be stepping down with the 400s, but WAS I wrong. I love them! I turned my subwoofer off so I could hear what the bass sounded like; it was quite sufficient! They don't rattle the pictures on the walls like my 125 does, but it is a GOOD, clean sound! I am very happy with the TSi400s and even happier that I have Crutchfield and Polk Audio standing behind them.

    I absolutely love these speakers. These are replacing a pair of Infinity speakers that where 25 years old. Had a Xmass party at my house and people started dancing to the great surround sound I created with these peakers a new Polk Subwoofer and (2) rear bookshelf speakers.
    Pros:
    Quick Delivery, Great packaging, Easy Install, Firts rate sound.
    Cons:
    I might make my neighbors really angry in the summer playing so much music!

    Great sound! These are the speakers we use for our TV/stereo. Always wanted Polk now I know why! Would recommend them to all. Researched on line and local stores and found this to be the best price. Would recommend these for sound and price. The size is perfect, they don't take up too much space and blend in well. Shipping was on time and they were packaged great.

    Crutchfield Customer Review (What's this?)
     
    I have a system set up for 7.2 surround and an Onkyo receiver that is capable of 9.2 surround(TX-NR818) with several Polk satellite speakers and wanted to up my theater to 9.2 surround. Talked with an Crutchfield advisor (Tommy) and he suggested a couple of these tower speakers as my right and left mains. Wow what a difference, the two mains give my set up a fuller(depth) sound from the front. Thanks Crutchfield and Tommy.
    Pros:
    Excellent medium base. Solid construction.

    Great, modestly priced speakers

    Written By Ray E., Miami, Florida on Thursday, October 10, 2013
    Crutchfield Customer Review (What's this?)
     
    These speakers were relatively inexpensive and sound great! Not quite enough bass but pair well with a Polk subwoofer that I already had. Probably would not use these alone without the additional bass butt overall they sound crisp and pack a nice punch with my Sony receiver. Love how they sound for movies and TV as well as music.
    Pros:
    Inexpensive, good, clear sound.
    Cons:
    Lacking in Bass.

    TSi400 are OK especially for the $$

    Written By Alan P., Greensboro, NC. on Monday, September 30, 2013
     
    The TSi400's are great for the price and in this case - you DO get what you paid for. Sound is good, bass is lacking (so DO get a Sub). I use these as surrounds and they perform just fine but they do NOT sound near as good as my Klipsch F-30's. The Combo is what gives me GREAT sound.
    Pros:
    Can NOT beat them at that price.
    Cons:
    Sound OK but not the Best. Use them as surrounds and mix them with an "audiophile quality" Main and add a Sub. Then you will be very Happy!

    Great sound

    Written By Geoff B, Clarksville, TN on Sunday, September 01, 2013
    Crutchfield Customer Review (What's this?)
     
    I have paired these with a Denon 4520CI receiver, Polk FXiA6 surrounds, Polk PSW-111 sub, and an old Infinity Video-1 (early generation center speaker) and they sound great. They provide a full, rich sound and do not overwhelm the center or surround channels, though that is heavily influenced by the receiver's level settings, I am sure. They have a nice range and reproduce music, vocals/voice, and sound effects well. I have been enjoying the Star Wars I, II, & III films with my kids with this system and the effects are great, even using a DVD quality disc vice a Blu-Ray. I am very happy with the quality. Additionally, I purchased these as Scratch & Dent models and they had a couple of cosmetic issues (small scratch on the top of one, small mashed area in the enclosure of the other, one cracked screen frame); none of these seems to affect the sound quality, though.
    Pros:
    Sound quality, mid- and high-range
    Cons:
    None noted

    Absolutely amazing speakers

    Written By Marcus, Cincinnati on Saturday, August 17, 2013
    Crutchfield Customer Review (What's this?)
     
    I have had these speakers for about 4 years now and cool not be happier with the sound quality and power. They are exceptionally crisp and balanced at even the highest volume levels. I paired mine with a Yamaha Rx-V467 receiver and a Polk Audio PSW 125 sub. They have plenty of power and make everything sound so much better than I have heard on anything else. You can really hear every sound from highs to lows that a song has. I can't say enough, you will have to hear them for yourself. Thank you Polk Audio for some amazing speakers. Crutchfield did an awesome job too. I would definitely recommend these speakers as well as the Yamaha receiver to anyone wanting excellent sound quality for music or surround sound.
    Pros:
    Sound quality, treble, bass, cherry finish
    Cons:
    None

    An Exceptional Speaker for the Price

    Written By Chas, Jacksonville, Florida on Friday, August 09, 2013
    Crutchfield Customer Review (What's this?)
     
    I am very pleased with the build quality of this speaker. The cherry finish is nice and the black lacquer piano tops add a "high end" elegant look. The sound is excellent, too. I had originally wanted the TSI 500 speakers but Crutchfield is out of them and they are no longer available. However after auditioning these speakers I don't see how the 500 speakers could be any better in my setup. If you were using them only as stereo speakers I would probably prefer the TSI- 500 speakers. Mine are in a home theater set up in conjunction with the Polk CS-20 Center Channel Speaker, the PSW 125 subwoofer and Bose 161 Surround Speakers. Because of the subwoofer bass is not an issue with these speakers. They produce fairly good bass but nothing like the subwoofer. The TSI 500 has larger woofers but it still could not compete with a subwoofer. This is why for home theater I am more than pleased with these speakers. I also have to tell you that in my opinion this series of speakers look better than the new ones replacing them. Gone is the black lacquer finish. Polk is using larger woofers but with a subwoofer it is not going to make any difference. I don't think the wood finish looks as nice either although I am sure they are very nice speakers. They just took some of the added elegance away. If you are thinking about these speakers I would not hesitate to buy them while they are still available. Crutchfield is easy to deal with and very fast shipping. No hesitation to order from them.
    Pros:
    High end looking speaker, very elegant Produces great sound for a speaker in this price range Good stereo speakers without a subwoofer Great stereo and home theater speakers in conjunction with a subwoofer Excels in the high and midrange frequencies
    Cons:
    None

    Woah!

    Written By John, Kansas on Friday, July 26, 2013
    Crutchfield Customer Review (What's this?)
     
    When I saw the UPS driver take these off the truck I was disappointed in the "small" size of the boxes. These were going to replace my old floor standing speakers that had 12" subs in them! I also got a nice polk powered sub the same day. I connected these speakers, and the new sub to an Onkyo TX-NR717, utilizing the bi-amp option. It's been a few weeks now and I have to say that I don't miss my old speakers at all. The new powered sub takes care of the deep bass and these TSi400's do all the rest! Very clear and full sound stage with music even at very, very high volumes I have not heard any distortion while listening to my kids dub step "music" that is bass heavy when the song "drops". Very impressive sound. Acoustic guitar sounds like they are in your room playing to you and piano comes out so great that you literally feel it, like you are sitting next to a piano for real.
    Pros:
    Awesome sound and they don't take up much room for a floor standing speaker in my opinion.
    Cons:
    I thought they looked small compared to my old school setup with 12" subs, mid, and horns but they sound so much better. You will want to have a subwoofer along with these to reach the lowest spectrum of course. I went with a polk 12" powered sub for the lowest bass because these speakers can probably handle the frequency most 8" subs would provide was my thinking.

    POLK TSi 400 SWEET DEAL

    Written By TOM, LEXINGTON, VIRGINIA on Tuesday, July 09, 2013
    Crutchfield Customer Review (What's this?)
     
    Fit and Finish - First of all, these speakers are well engineered and built. They (cherry finish) look so high end you can really show them off all the time, I mean to friends, relatives and guests! I currently have them placed in the front of my amp so the speaker cables are running to the sides actually ahead of the amp/cd player. This setup is working well as to the speakers "imaging" correctly and I have had great results right from the start. Sound - They sound incredible. I even waited several weeks to allow them to break-in correctly, before doing this review. I wanted to make sure I was clear about really how good the sound was and also how good the sound would stay. I am using the NAD C326BEE amplifier to drive these Polks and the sound is, again, well balanced and accurate. I was going to stay in bookshelf speaker territory because I did not think you could get a decent floor stander for under $1000.00, Boy was I wrong. The bass extension is in the 30hz range, and in simpler terms sounds very low to the ground. I can actually place the bass guitar in the room as distinct from the piano, drums, and vocals. Also, the clarity of the midrange is warm but with plenty of detail and the right "imaging" texture for placing the band in the room before you. Finally, the treble is not harsh or grainy, and delivers the right high frequency information right to the listeners ear. I am saying after just three weeks this is all the "high end" I could ask for!!!
    Pros:
    These Polk TSi 400s are the best value in audio today. Crutchfield has them priced well under the $500.00 mark and this is astounding for a pair of beefy floor standing units. I am not in the habit of over rating a nice looking and great sounding set of speakers. I believe these 400s are just hard to beat unless you want to spend over a thousand bucks. I have the Polk TSi 100s as well in a "home library" setup, as they sound amazing themselves. Get some of these TSis before they are sold out!!
    Cons:
    I have no cons about the Polk Tsi 400s. That being said, higher quality amplification such as Nad, Marantz, Cambridge Audio, Yamaha, and Onkyo give these speakers their best sound. Crutchfield sells all of these stellar brands under one roof,, one should seriously consider any of them to get great sound!!

    Exceptional Sound from These Polk Speakers!

    Written By Snappitz, East Stroudsburg, PA on Monday, July 08, 2013
    Crutchfield Customer Review (What's this?)
     
    I waited five weeks to be sure I had everything at home tweaked correctly before doing a careful review of my new Polk TSi400's. Matched these speakers with an Onkyo TX-SR505 AV receiver (75watts/channel) and Polk TSi CS10 center channel. The details: 400's are bi-wired to receiver with 14 gauge wire, room is 16 x 20 with hardwood floors, no rugs, 400's are 10" from front wall, 24" from sides. So, playing vinyl from my 32 year-old Dual turntable in stereo mode the 400's sound great with full range of dynamic sound, clean and accurate. Audio CD's sound just as good with the Onkyo's theater dimensional mode adding more sound stage with the center channel helping out. Watching DVD movies was a pleasant surprise. I had audio connected with component cables and was getting Dolby Pro-Logic II from DVD with great sound. I went out and bought HDMI cables to unleash full Dolby Digital and it made a huge difference! I tested with action sequences from Skyfall, Dark Knight Rises, Incredibles and the sound was huge, no distortion and very accurate with the bass resonating the floors. Keep in mind this is without full surround sound, just the three speakers and no subwoofer. With the 400's going down in the 40 hertz range I can't imagine needing a sub unless you want your Low Freq Effects for movies in the 20's and 30's... or unless you have shag carpets. Ya' never know. All in all these Polks are an amazing value for under $500/pair. I will be adding TSi surround speakers in the Fall.
    Pros:
    Amazing sound, plenty of power and bass on vinyl, CD or DVD, beautiful finish, small footprint.
    Cons:
    None.

    I started with the Polk center channel and has since moved to the TSI 100, to the TSI 300 and recently purchased the TSI 400. The sound is so crystal clear with a superb bass response. The movies are a pleasure to see an hear with these speakers. All of the sound comes out as in the movies and the way the director intended to enjoy the movies. The sound that comes out of the speakers are neat and exceptional. Highly recommend the TSI 400 speakers. My decision now is should I go and buy the TSI 500?
    Pros:
    Neat superb sound
    Cons:
    Larger than expected but the sound compensate for this little inconvenience.

    I replaced my Sony bookshelf speakers with these and never been happier! When standing in the middle of the room and I set the amp to 2 channel, I have to strain to hear that the surround speakers are NOT on. The sound imaging is amazing! The bass is good for music, of course a sub is always desired. The cherry wood looks classy in my living room!

    Excellent speakers

    Written By mesaman11, Delta, CO on Saturday, February 23, 2013
     
    I bought these speakers and got a free PSW111 sub as a package. What a deal! The frequency response is excellent and such an improvement over my ancient bookshelf speakers. I run a vintage Marantz receiver with 80 watts per channel and get incredible sound. I recommend getting the sub for adequate bass response.
    Pros:
    Great frequency response and balance. Can use sub with an amp or receiver without a dedicated sub out.
    Cons:
    None

    So far, pretty good

    Written By jacomus, cincinnati, OH on Monday, February 11, 2013
    Crutchfield Customer Review (What's this?)
     
    Honestly , I expected a little more from the TSI400s but I won't complain too loudly yet. The mids are pretty good, the highs are average and the lows are as well. I paired this with an 8" Polk Sub. It sounds alright but I am not blown out of the water by any means. I am driving this system with a dedicated Pioneer Class D3 amp with 130W @8 ohms. The speakers peak at 200W so I would expect quite a bit more out of them than I have heard so far. That said, I am going to give it another week or so because:

    1. Apparently, there is a break in period for the speakers to sound their best. 2. I have heavy shag carpet wall-to-wall which muffles the sound.

    Soon, I will be replacing the carpet with hardwood and these will be broken in by then. I will come back to update the review more then.

    Crutchfield Customer Review (What's this?)
     
    For the money, I'm not sure you can beat the impressive sound reproduction these TSi400's produce. To my ears Polk speakers have always produced clean highs, rich mids, and smooth bass. These speakers deliver all three. Alone these speakers sound good, but adding the PSW111 sub completes the package. The speakers are in our family room (23" x 15") and fill the room perfectly with movies, tv, and music. I listen to a wide spectrum of music including rock, classic rock, country, jazz, blues, and some heavy metal. These speakers handle all very well. I am very satisfied with my purchase of the speakers, sub, and from buying them from Crutchfield.

    I'm not an audiophile by a long shot, but I do appreciate good music. I have them as my front L/R in my backup suround sound room, living room which is also the primary music room. I find I end up listening to them in 2 channel alot because they put out great sound. They have the polk cs10 center channel and psw 125 sub attached to a yamaha 473 (and some original in ceiling surrounds that need to be replaced) which they sound great with also, but as primary music speakers, i really like them...and as a surround system no complaints...but i havent really used them for that purpose much

    Exellent speaker for the price, beautiful cherry wood makes them stand out in any room, even with other colored stained woods. As well, the top of speaker finished in piano black. Nice touch of class. Very good sound quality. Hooked up as main speakers to audio/video amp/reciever in a large open living/dining room. Sounds great standing or sitting anywhere in these combined rooms. They arrived sooner than I thought with the free shipping. Am considering purchasing another pair to add to system. They replaced my very old and finally blown Infinity Kappa 6's which I bought way back in 89 for $600 a pair while in the US Army stationed in Europe...big money for back then. These Polk Audios sound just as good if not better, so I hope they will last as long as my old ones.
    Pros:
    Sound quality, fit and finish , cherry wood is beautiful

    Polk Audio TSi 400

    Written By ajr, Rochester, MI on Sunday, September 09, 2012
    Crutchfield Customer Review (What's this?)
     
    Surprising response. For the price excellent imaging. Mid range strong but not "preachy". Snappy highs. Bottom good, but I added a Sub bass and that did the trick. Bottom firing port is better when tower is placed on hard surface, however with the sub bass it doesn't matter. Room filling sound. Handles 150 W rms with ease. Even when the amp is close to clipping, no distortion from these towers. I'm certain the TSi500 may add a little more depth, but where do you stop? Really, for about $250 per tower, it's a real bargain!
    Pros:
    Looks great, sounds good, with sub bass, is a real room filler.
    Cons:
    Just that it's truly a middle of the pack tower, and it would be easy to "nibble" up to the next level, then why not $100 more? Heck, how about $150? Stop here. It really works

    Written By Cody C, Gardner, MA on Saturday, January 07, 2012
     
    I am very pleased with the TSI400 The highs are very crisp and detailed while the lows are punchy enough to get by without a sub if your listening to music. However If you plan on using them primarily for movies i recommend you purchase a small sub. I a long time musician with musically trained ears and i would easily recommend these speakers . reason i rated 4 stars was the tweeter could be higher like i said.
    Pros:
    beautiful speakers, very well balanced highs and lows
    Cons:
    the height of the tweeter could be a bit higher so it would be closer to ear level

    I bought these as part of a system to replace my Bose Acumass 10 speaker system as I wanted more bass than my small Bose speakers could provide. I thought the woofers in these and the Polk surround sound and center speakers I purchased could provide that extra oomph without the need for a powered sub-woofer. They sounded great, but to get the true "theater" sound you need the sub-woofer which I got later. Great sounding system and the cherry colored speakers are beautiful too. They are also pretty slim making placement easier. HIghly recommend the speakers and Crutchfield is great.

    Crutchfield Customer Review (What's this?)
     
    Got a great deal on these speakers. Included a free sub woofer. Using for 5.1 surround
    sound for HD TV and Blu Ray. Excellent experience without breaking the bank. Sound
    remains crystal clear at low and high volume.

    WAS ABLE TO COMPARE THIS W/ THE TSI 300,THE EXTRA WOOFER MADE THE WHOLE
    DIFFERENCE IN SOUND RE-PRODUCTION,BASS HITS BETTER AND HARDER.THIS MODEL JUST
    PLAYS LOUDER.GOT IT ON SALE MAKES IT WAY BETTER!!VERY SATISFIED!!
    p.s. the reason for the 4 stars is nothing is perfect.

    these speakers were every bit and more what i expected. pure crisp sounds no matter what the volume.i have a live audio of a Queen and Paul Rogers Live in the Ukraine and it sounds like you are right there. Beautiful sound out of a nicely priced speaker.

    Great Speakers

    Written By Link, Houston, TX on Thursday, May 14, 2009
     
    I bought these speakers earlier this year.

    Pros - amazing sound given the price. I liked these better than infinity
    P362s and the klipsch Rf-10s when i compared them. the mids and highs
    were what got me, I have a sub so the lower frequency from 80 down was
    never a concern for me. Mids are lifelike and when you increase the volume
    the speakers keep taking power and start sounding better and
    better....and i reached a point where i did not want to have cops at my
    place :) ....they are that good. Highs were crisp and clear especially in
    soundtracks and movies...i felt like i was in the movie. Also the cherry finish
    is top notch with the black top and bottom plates. with the grill off the thing
    is beautiful.

    Cons - If there is anything i can pick it would be that one would defintely
    need a subwoofer to completely enjoy them. If you are not planning on
    getting a subwoofer and just run them in 2.0 then start looking
    elsewhere...the infinities had good lows but not as good highs as this one
    so its a tradeoff on what you want.

    For this price a great sounding/looking floorstanders you definitely cant
    do any better in that price range....and sky is the limit when it comes to
    audio...use your money wisely and buy these.

    HOW WOULD YOU COMPARE THESE POLKS' TO THE KLIPSCH REFERENCE MODELS TO MOVIES & MUSIC? HOW MUCH DID YOU PAY FOR THESE AS A PAIR? [ DELREY  Feb 11, 2014 ]
    5 answers
    • I am very pleased with the speakers I can't remember the exact cost that I paid but I would definitely recommend these in the advice that I received at the time from Crutchfield [ JASON   Feb 16, 2014 ]
    • Not familiar with Klipsch. The speakers provide high quality sound at a reasonable price per pair. Design is first rate.I use Polk SB 50 for surround sound. Highly recommend if space is an issue. Sub-woofer a must [ WILLIAM   Feb 12, 2014 ]
    • Sorry, don't remember the price and can't look it up right now. Can't compare either because I don't have the Klipsch to compare them too. We are very happy with them though. They are in large basement room for playing pool and listening to old vinyl. Working out great. [ DAVE   Feb 11, 2014 ]
    • Hi, if you are looking for just a home theater the tsi400 can do the job but if you are looking for a clarity, details, and a really good sound in movies and music you can try the klipsch. I just bought a used pair of reference 600 from a friend and now I'm thinking in buy another pair from Crutchfield. And I paid for the polks almost $600. If you have another question just let me know. [ RUSLAN M   Feb 11, 2014 ]
    • The Klipsch are also amazing speakers. I have been a long time fan of Polk. My car speakers as well as these TSi 400s down in my den for the 7.1 I have. Once I heard these at Best Buy, I ordered them from Crutchfield that day. The research Crutch offers is the best around.....but you do need to hear or see a product in person before buying right? These are the best bang for the money. I think I paid 500 for the pair? Maybe 225 a piece. I loved them so much I purchased the CS 20 to replace my center channel. The speakers have a rich sound. Lows are great while the high tones are superb. I have a 5 year old Sony amp pushing them. Pull the trigger and buy them. I researched them for 2 months before buying. [ DAVE   Feb 11, 2014 ]
