Our take on the Polk Audio TSi400 by Crutchfield's Loren Barstow
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 look, 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.
I am currently building and put these speakers in a large empty room and they played the room well.

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.
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.
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.
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.

Looking for upgrade from TSi 100. And to make a coherent surround system. Used the TSi 100 pair for the rear channel. [ Alan Jun 09, 2017 ]

POLK IS THE BEST SPEAKER FOR THE MONEY. [ Joseph Jan 25, 2017 ]
The price was first... specifications of speaker was second... Crutchfield had them in stock was third, and I love shopping at Crutchfield. [ T Dec 23, 2016 ]
Adding this to my surround system this is the final pieces to my 7.1 surround sound system [ John Dec 23, 2016 ]
Because I have the bookshelves version of these speakers and wanted the bigger sound-stage that a floor standing version should provide. [ DEMETRIO Dec 21, 2016 ]
I PURCHASED A SIMILAR PAIR LAST YEAR AND LIKED THEM [ Mark Dec 13, 2016 ]
I ordered a Denon surround receiver a few years back and love it. I suspect that my low-end surround speakers are not giving me the full benefit of the Denon - so now I'm interested in upgrading my speaker system to match the quality of my receiver. Polk has a good reputation and these seem like a good fit as an upgrade to my current towers - and you can't beat the price. [ Andres Nov 21, 2016 ]
Beautiful sound [ Carlos Nov 10, 2016 ]
Recommended by Crutchfield [ Michael Oct 25, 2016 ]
I liked the size. The sound is very good and a very good price. Slim and easy to place. [ Jose Jul 26, 2016 ]
Needed a set of speakers that will pair well with my Polk CS10 center channel speaker. Paul, a Crutchfield advisor, recommended them. Looking forward to better sound and matching speakers. [ Joshua Jun 02, 2016 ]
Recommended by a friend and the great price [ GREG Apr 25, 2016 ]
I spent a few minutes of research--- These are one of the most popular sellers---people with a whole lot more time and experience loved these speakers ---that is good enough for me! Thanks for making it easy. Shopping on line can be such a time sink! [ lowell Apr 15, 2016 ]
Perfect power for my surround system... [ PETE Feb 17, 2016 ]
Research and good input from buyers at your site You guys have a good return policy [ Teunys Jan 07, 2016 ]
Great deal!!! Hard to pass up this much sound for this price [ MICHAEL Jan 03, 2016 ]
Bought these to complete my system. Liked the sound and looks. [ Jack Jan 02, 2016 ]
I bought these for a few reasons. First, Polk makes great sounding speakers. Next, these will complete my Polk set up. All my other speakers are Polk except my front mains. Lastly, these seem to be discontinued which means you can get them at a great price so they can clear out old inventory. I was going to get the 300's, but decided to spend a few more bucks and get the 400's. I'm sure it will be money well spent. [ Carl Jan 02, 2016 ]

In my humble opinion, yes it gives more presence. Depends more on music preferences and intended use. [ Carlos Nov 29, 2016 ]
2 answers I have a chance to get a really good deal on a tsi 400 and a tsi 500 bc they only have one of each. I have a Denon rec/amp running energy classic 5.1 surround speakers. Thinking ab replacing front speakers with this floor stand speakers bc such great deal. How would a tsi 400 paired with tsi 500 sound??? Uneven?? [ Mancave dweller Feb 25, 2016 ]
I am very happy with my tsi400's. They are durable, built to last. I shipped them overseas twice and they are performing like I just bought them. I have been using them with a Polk audio sub woofer when I watch movies and I have no complaints. My Denon avr400 providez 185watts per channel that make all the difference. As far as pairing them up with the tsi500's I would assume if the range of frequencies are almost the same then ok. I believe the cross over for both models are set to 2500 hz. Not sure if this will help you. If it were me I would pair speakers of the exact same make and model. [ Sean Feb 27, 2016 ]
Not sure how they would react together, I can say I have a set of tsi 400's paired with a Polk 10" sub, it shakes the walls, clear and crisp [ Richard Feb 26, 2016 ]
Well Randy, if the rating of your amp is 80 watts RMS it will be fine, but if it's 80 watts peak and you want to crank it up so the neighbors can hear your choice music it might not sound so good. You didn't say what amp you had. Does it have a low THD? The speakers you chose are fantastic but the audio that comes out is the audio you put in. In short if you have an amp with great specs buy the speakers, if the amp is not so great, buy the amp first. I hope this answer will help you in making your decision. Best of luck Randy. [ Rey Dec 15, 2015 ]
I'm driving these with an audiolab 8000a (60w) and they sound just fine... pretty good, actually... your 80w should be plenty... [ GARY Dec 15, 2015 ]
YEs, it is enough [ ALLEN Dec 15, 2015 ]
I've got a 500 watt Technics recvr thats 20 yrs old and can't turn it up more than 1/3 the way and they sound great. If yours is a 5/1 and you have good rear and cntr speakers 80 per should be plenty of power. My room is 25x25. Hope this helps [ Phil Dec 14, 2015 ]
3 answers I just installed a Def Tech 1000/2000 for a 5.1 setup and am extremely pleased with the sound, particularly the 2000 center speaker. I was looking for clear definitive voice and conversations in movies and am again very pleased. Now I'm considering upgrading to 7.1, my current receiver supports it. Can anyone offer any suggestions pro or con in using these as my front speakers, and the Def Tech PM 1000's for the surrounds and rears? Also any comparison to the Polk Inf Primus P363's instead of these? Both would be in my price range. Again my foremost interest is in the distinct clarity of voices and conversations in movies with a lot of back round sounds. As you may have guessed, I'm getting older. Thanks for any help or suggestions. [ Bill Oct 07, 2015 ]
I have these speakers as my front right/left and they are excellent. You will need a sonically matched center channel speaker to bring out the clear voices you demand. I have a Polk CS20 myself that I am very pleased with. I'm not sure if they are still available so get the one in the same Polk series that will match the front speakers. The Crutchfield folks will help you with that choice. Hope this helps. [ Roger Oct 13, 2015 ]
I am very pleased with these speakers, voices/conversations are much more clear/distinct than my old set up of the Bose cube speakers. As for getting older this is same reason I purchased these speakers, wife was getting on me about cranking the volume to hear the dialog. Now I no longer need to make my wife's ears bleed. [ TERRY L Oct 07, 2015 ]
I use the TSi400s in my living room as front speakers, and I love them. They offer way more sound than my relatively small room requires, but they are diverse enough to behave accordingly throwing her the entire volume range. They're great for everyday television, HD movies, and music as soft or loud as you wish to push them. I have always been impressed with the clarity, but that's such a unique opinion to each person's ear, I hate to say that you'll think so too. I would definitely recommend them based on my experience with them for close to two years now. [ Thomas Oct 07, 2015 ]
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. [ rmlora 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 ]
The MC Series Polk speakers are timbre matched to their TSi series freestanding speakers. We have the MC80 & MC60 in in-ceiling and the MC85 in in-wall. [ Larry Dec 20, 2015 ] Staff
