The Do-It-All Bookshelf Speaker
Small in size, big in performance, the TSi100 is a great speaker to use for wall-hanging surround speakers in a TSi Series home theater (heavy duty wall-hanging brackets are built right in). Or, use them as main speakers in a small room, where performance is key but size is a consideration. Add a subwoofer to a pair of TSi100s and you have a truly dynamic high performance stereo pair for a truly surprising price.
Unlike other speakers in this price range, TSi enclosures are constructed of extensively braced, solid MDF with 3/4-inch baffles. This virtually eliminates internal resonances and damps energy-stealing vibrations, for more efficient operation and more transparent sound.
Beautiful pewter accents, a high gloss piano-finish black top plate and your choice of stylish black or cherry wood-grain finishes make TSi speakers a part of your decor.
Polk’s proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
TSi design combines smaller drivers (for more overall driver area with less driver mass) and narrow baffle geometry, for wider range and more spacious soundstaging, so every seat in the house hears a prime performance.
Unlike horns or metal domes, silk dome tweeters deliver clear and detailed highs, without fatigue, even at high volume.
Durable, efficient, and tuned with our Dynamic Balance process, TSi Series polymer cones produce smooth, natural sound.
Surprisingly deep, musical bass response thanks to our critically tuned flared port venting system, which minimizes port noise ("chuffing") and smooths the turbulence of port air flow, to reveal big, full-bodied bass that blends effortlessly with the speaker’s overall dynamics.
All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
Our high efficiency design results in sound that’s spacious and clear, warm and realistic, when combined with practically any electronics, even the most modestly-powered amplifer or receiver.
Our high performance crossover system boosts performance with premium components, like mylar bypass capacitors, to extend response in the higher, more detail-oriented frequencies.
Gold-plated, professional-style 5-way binding posts, for the most secure connection options.
All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.

Crystal clear midrange and highs, very efficient, better performance than speakers costing 3 times as much money. OUTSTANDING build quality.
I have been a music freak my whole life and have had all types of stereo and home theater systems over the years. I can tell you right now these speakers are incredible. I am currently using the TSi100’s as my Fronts with a Sony AV Receiver, Mirage Subwoofer, Bose 161 Rears, and a Sony Blu-Ray Player. Concerts ranging from Fleetwood Mac to Amy Winehouse are stunning – these speakers are so crystal clear they will generate goose bumps. The imaging on these TSi100’s has to be heard to be believed! Nice work Mr. Polk.

The TSi100 is good for a small system running at low volume. Good clarity in the mid to high range frequencies.
Bass is muddy and boomy at higher volumes; a subwoofer is definitely needed in larger rooms at higher sound levels. And for the price of a subwoofer you could move up to a tower.
For the past two weeks I have been testing a pair of TSi100s in both my office rig and my main two channel system. Right out of the box I was initially disappointed that the connectors did not appear to accept banana plugs, but later, reading the manual, I learned that the little caps on the hex head screws are removable to expose the banana receptacles. That issue solved I set them up in my office flanking my dual monitors. They are about 42 inches apart and 24 inches from my ears. I use an old 70 wpc Yamaha RX-V496 AVR (with all effects off) connected to my G5 PowerMac with an optical cable, thus using the DAC in the AVR. In my office I mainly listen to internet radio and my own iTunes collection. At first the speakers had an unpleasant resonance with the desktop that they sat on. I solved this temporarily by putting a couple layers of bubble wrap padding under them. In this close-in configuration the TSi100s deliver clear highs and a good bit of bass. There is a real sweetness to violins and clarinets that is often difficult to reproduce. I am easily able to distinguish between the sound quality of Apple Lossless compression and the inferior lower bit rate MP3s. (I will have to re-rip a bunch of CDs.) At the low volume levels that I normally set in my office these little Polks are a real pleasure and easily outperform the OWM5s that I tested a few months ago. Next, I set the speakers up in place of my Monitor 10s in my main two channel set up, in an 8 foot equilateral triangle with the sweet spot. They were driven with a Parasound HCA-1000A with an Akai AP-206 turntable as the source. At 125 wpc the HCA-1000A is definitely overkill for the TSi100s, but I was careful not to overdo it on the volume. The first thing I noticed about this setup was that the bass notes, which sounded fine at a lower volume level in my office became boomy in the larger setting of my living room. So in order to tune in the bass better I borrowed a Polk PSW10 subwoofer from my SurroundBar rig and hooked it up with speaker level inputs passing through to the TSi100s. After some experimenting, 90Hz seemed to be the best crossover point. I could then adjust the volume on the subwoofer to an optimum level for best bass response without boominess. Over several listening sessions I was consistently impressed with the size of the sound from these little speakers. My living room is 13' x 19'. I could have them as loud as I wished (not house shaking, but still plenty loud) without distortion. Having been relieved of the bass frequencies by the subwoofer, these speakers put out a sweet, clear sound that I found very pleasing for jazz and classical music.

Bi-Amp connections and low frequency response.
So far, none!
Got these at Best Buy and tested them out there. Compared to other 2-way models they had, I immediatley recognised the difference in the low frequency range. Plus with the Bi-amp connections, I had to get these! I really like the low frequency range and the warm sound these give me. They don't have the thump that most people would probably like but for the size and price, Awesome speakers. I just use these in my bedroom for music and the occasional movie.

Sound comes alive with these, great as surrounds or main speakers.
These have mounting brackets but they are a little big to hang on the wall.
Like another reviewer I demoed these at Best Buy and it was no contest.These speakers could easily be your mains l/r I am using as my sides and rears and It gives me a flawless sound stage paired with my tsi 500's and cs20.Highly recommended If you like clean crisp highs warm and mids.

clear sound and nice price
lack of a good low frequency range. but it perfoms great with acoustic instruments and low timbre voice. needed to be assisted by a subwoofer.
even if it's made for surround it works pretty weel as front stereo speakers. the high's are a bit bright but as any other speakers, you have to set it up with your receiver. it lack a bit of bass but with a subwoofer it will perform greatfully. nice entry level speakers.

Size, terrific sound, wall mountable, and the good price.
Until now I don't found any weaknesses.
I get very satisfied with the sound of this set of speakers do for the value. The bass and hights are really balance as it said in the package. And beacause I have a limited space for the front speakers its size was perfect for my home theater cabinet. I listen a lot of music generes and with the other speakers I have to adjust the tones and the volume to get the seemed sound in high volume. With the TSi100 it was no necessary to adjust the tones of the A/V receiver. In conclusion I highly recommend this set of speaker and you can not regret.

Price for performance is hard to beat in my eyes.
Lows and some mid-range could be better.
I have these as replacements for some 12 year old Sony Towers and they sound amazing. I put these up against Klipsch and Definitive Tech when I was looking to buy. I couldnt believe the value for the money. They sound just as good or better than my buddies Klipch Towers. They are very smooth and mellow. So if you're looking for something blaring, look elsewhere.

Very good sounding.Polk's still in the game.
No competitive pricing.Better deals do exist elsewhere.Sorry.
Purchased a pair of these at Best Buy for fronts in a surround system and I was quite happy with the sound until I heard the Energy C-100s which blew the Polks clean slap azz out the room and I returned them for the Energy's and saved $80.

Good workplace "background" speaker, or second room "ambience" speakers. (Any low volume application)
Would not try to use these as primary set with the hopes of adding a sub. The bottom end is just too "boomy" when driven even at moderate levels.
Dorm Room/Beauty Shop speakers. Design tries to compensate for shallow bottom end, but ends up sounding a bit boomy & a little muddy, especially at higher volumes. I ended up EQing the bass way down to smooth it out. At no time did I forget that I was listening to a set of speakers, but the highs were decent. For the price, there are better choices out there. Sorry Polk, I'm a HUGE fan, but these miss the mark.

Highs are tight, brilliant. Great compact size, and a terrific price.
Thin midrange performance.
I purchased these speakers recently along with a Polkaudio powered subwoofer based on reviews here and elsewhere. I use them to replace some tower speakers (I'm downsizing). There is a lot to like about these speakers including the price. However, midrange is definitely thin - I get sparkling highs and good lows from the subwoofer, but the midrange needs help. I'm running these off of an NAD T770 receiver which delivers nice full midrange on my previous speakers. They are worth the money, but if I had it to do over again, I'd spend more to get strong midrange performance. And, yes, I have placed these speakers close to a wall as recommended.

Clear mids and bass.
I did'nt buy them earlier.
Well I just got my speakers and they are better than expected. Check out and Blue Ray movie and prepare to be blown away. My IPOD and Yahmaha AV works so well with these speakers. Now I'm ready to buy the TSI200 to complete my 7.1 home system.
by Shaun, May 16, 20131 out of 1 people found this review helpful.
The great sound that come from that without being a terrible bass monster. Not overdesigned just perfect fit for the surround sound system for a 7.1 or 5.1 system
Unfortunately not enough color selections
What a great little bookshelf surround speaker all-around great sound.

Excellent build quality, accurate highs. Great for HT use.
Not enough punch for hard rock/metal.
I got these to test from the Polk forum demos. I was surprised to see these sitting on my doorstep one morning and brought them in, letting them sit for a couple weeks before I actually had some time to break them out. The finish on these speakers are better than on my Monitor 70s for sure, overall build is quite excellent and very upscale. On to listening... I popped in some Diana Krall, the first thing you notice is that these have fair bass response from such a small speaker, they do have a port in the back. I set my Pioneer Elite to DIRECT which means no processing, just some EQ. Jazz sounds perfectly fine on these things. Second I popped in some metal/hard rock... the first thing some people might say with music with a lot of cymbals is that these are kind of tinny, I would say they are more "accurate" at higher frequencies... not quite as "flat". If I wanted to keep these speakers I would probably double amp them with the Monitor 70s to get more of a high frequency punch. For hard rock/metal these obviously don't have the punch or dynamic range compared to larger speakers like the Monitor 70s. Watching movies and TV these are pretty spot on since they're designed mostly for this purpose, general HT use. Pair these things with a subwoofer and you have a pretty nice HT setup.
