Our take on the Polk Audio TSi100

Add the Polk TSi100 to your system to enjoy open sound with wide staging and precise imaging. These speakers feature Polk's exclusive Dynamic Balance® drivers that undergo laser testing to find and eliminate resonance points, ensuring that everything you listen to sounds clean and accurate. The silk tweeter delivers sparkling highs, while a polycarbonate woofer churns out smooth mids and lows. The braced MDF cabinet fights resonance so the details in your music and movies shine through, even when you crank up the volume.

Just team these speakers with a Polk powered subwoofer for full-range sound. They also work great as surround speakers when used with Polk's larger TSi models. And the TSi100 looks good, too. The woodgrain vinyl finish and elegant piano black top plate complement just about any décor.

Replaced an older pair of Polk bookshelf speakers with these. All I can say is Wow! I put them in the garage, and my neighbors are commenting on the great sound! Driving them with an older Onkyo receiver and an iPhone. Sound a lot bigger than they look.

    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: Each speaker features a 5.25" bi-laminate composite dynamic balance driver which is light and stiff for deep bass response and low distortion. For high performance durability, each woofer uses a butyl rubber surround.

    Silk dome Tweeters: Each speaker features a 1.0" silk dome dynamic balance tweeter for detailed highs. Each 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 53Hz-25kHz and the -3dB frequency response is 61-24kHz.

    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. First 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 bookshelf speakers feature a rear-firing port.


    5-Way Binding Posts: Each speaker has a set of gold-plated 5-way binding posts.

    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.

    Rubber Feet: Each speaker comes with four self-adhesive rubber feet so they will sit securely on your speaker stands or shelf.

    Wall Mounting: Each speaker has a keyhole slot bracket on the back panel, allowing the speaker to be mounted on the wall using optional mounting screws (sold separately). A wall-mount template is provided to assist you.

    to go with my new sony home receiver i purchased here. [ HAROLD G  Jan 24, 2017 ]
    These things sound very good especially for the money. I have a pair in the cherry finish and a pair in black in my surround system. I will replace the black ones with these in my surround system and use the black ones with my vintage receiver. [ Timothy W  Jan 15, 2017 ]
    Wanted to replace old speakers and the size of the Polk Audio fit the bookshelf space. [ Robert  Jan 04, 2017 ]

    Spoke to Polk - these can be placed on their sides to fit my small space. Also the item was half price because Polk was coming out with a new speaker line. [ Bob A  Dec 14, 2016 ]

    Really like the color. Recommended by Doug [ Badrinarayanan  Dec 27, 2015 ]
    Had just got a couple of Poke towers and a Sub for my home theater system that sounded great but it put the shame on the surrounds that had come from one of those all in one packages years ago so under the advice of Troy (one of your techs) I purchased these to match. [ Mark  Dec 17, 2015 ]
    They look great! [ NORMAN  Dec 15, 2015 ]

    13 questions already asked

    They would be compatible with any receiver. I have an Onyko receiver that I bought with the speakers and they sound awesome. A lot of sound from a book shelf speaker. [ SAMUEL  Jun 06, 2017 ]
    I can't say for sure but I don't know why they wouldn't be. As long as you have the wires to connect them there should not be any problem. Speakers will work with any receiver. Good speakers for the price [ HAYWARD H.  Jun 06, 2017 ]
    Without a doubt. I just looked up the receiver and it has regular speaker jacks. So yes. These would be a great addition to your system. I would definitely? recommend a subwoofer for the lows. These speakers sound great but they lack a detailed low below 70hz. [ Eric  Jun 06, 2017 ]
    Jose, doesn't the receiver have an 8 ohm power rating or option? My main concern might be not enough power to the speakers, and that would result in a less than satisfactory sound from the speakers. If you haven't already done so, I would check out the Polk Audio website and double-check the speaker specs to make sure your setup would work out! Regards, A.J. [ Alfred J.  May 26, 2017 ]
    At high receiver output you might. I've had mine hooked up to a 100 W RMS Rotel integrated that sounded great after break in. Great little speaker for female voice and sax. [ Stephen Dougla  May 26, 2017 ]
    No, they are standard speakers. [ WILLIAM  Mar 15, 2016 ]
    These are standard speakers. If you need Bluetooth, then you'll need to do it via a receiver. [ JEFFREY W  Mar 15, 2016 ]
    The better gauge wire, the less signal loss you will have. We always use 14 gauge, though 16 gauge would work. [ Robin  Dec 02, 2015 ]
    I don't know. However, mine died after 18 months. I recommend you consult with an expert at Crutchfield. [ Federico  Dec 01, 2015 ]
    To answer your question I am using a 12 gauge wire seems to perform better and also helps keep my amp run cooler and the speakers sound clear and less resistance from the output from the receiver [ THOMAS  Dec 01, 2015 ]
    There are speaker wire terminals on the back of these speakers. You would simply need to run speaker wire from your receiver to these speakers. [ Jeff  Dec 15, 2014 ]  Staff
    Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Krissy  Oct 27, 2014 ]  Staff
    I forwarded your question to an Advisor and they responded with the following: I'm afraid those are only available in black and we don't offer them in Cherry. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Apr 09, 2014 ]  Staff
    I forwarded your question to an Advisor and they responded with the following: That older Marantz stereo receiver is rated at 40 watts x 2 at 8 ohms so it'll drive the Polk Audio TSi100 speakers fine. Since they are small, you won't get a ton of bass from them but the Marantz is strong and should do a great job with those smallish bookshelf speakers. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Mar 25, 2014 ]  Staff
    I bought these speakers and they sound great especially for home theater. But, you shouldn't put them back against a wall like you said. I don't know why they have that mounting option on the back. The rear port I believe is part of the "bass reflex" system for more base in a smaller speaker, but it needs to move the air (thus the space from the wall). For musical listening, or if you have a subwoofer already, you might want to consider an "accoustic suspension" speaker (without the ports) if you want to place the back of them against the wall. I don't know if polk makes one of those since the home theater type speakers are so popular now. [ SCOTT  Mar 20, 2014 ]
    Hi Eric K! You're right, the TSI100 is rear-ported, it does come with a key hole type kind of bracket that for my personal taste is useful for surround mountings but you got to put some rubber shoes on them or otherwise you will hear some vibrations coming from the speakers shoes. The other question is if should you mount them against the wall? Well it depends IMO, if you're using them as surround you won't be able to hear much difference ( I have them against the wall mounted with the original key hole slot and I have them as surround 4 of them) but if you're using them as main L and R channels I will put them about 12 inches of the wall. I hope this gives you a better idea ! Have fun! And welcome to great sound! [ PEDRO  Mar 20, 2014 ]
    I've had no problems and mine are up against the wall. . Good speakers! [ KEN  Mar 19, 2014 ]
    Thank you for the response. [ Eric  Mar 19, 2014 ]
    The port is on the back but the bracket allows the woofer to "breathe". I used a single 3" Sheetrock screw in the wall. If you let it stick out about 1/2" it will mount just fine. I have a 7.1 polk setup with TSI400,300,100,CSC20, and a Pro440 WI. They totally rock! 90watts each channel. Monster speaker wire. Highly recommend TSI series. [ Phoneman  Mar 19, 2014 ]
    The mounting brackets provide about a 1 inch buffer between the speaker and the wall. So the port stays clear. These are truly wonderful speakers for the price. [ Suzanne  Mar 19, 2014 ]
    Hi. The answer is yes. These speakers (Polk Audio TSi100) would work very well with your Luxman R-1030 receiver. It has 30 watts RMS and would handle very well these speakers that need a minimum of 10 watts RMS. [ JESUS  Apr 03, 2017 ]
    yes [ DAVID  Apr 01, 2017 ]
    I believe they will work very well. The tsi100 are efficient speakers. You only need 20 watts per channel for them to sound full. your receiver seems to have a clean 30 watts per channel. According to the specs,the total harmonic distortion is at 0.05%(the lower the number the better and cleaner) for 30 watts into 8 ohms, which is suppose to mean you have a strong 30 watts. It would be more than 30 if it was rated like the amps are rated today. You have to spend over $1000.00 to get numbers like that these days. [ Antoine E.  Apr 01, 2017 ]
    I assume would. Power requirement is not severe. I tested them on a Yamaha CR-420 - at least 15 -20 years old and they worked fine. [ David  Apr 01, 2017 ]
    No. this is a passive speakers and need a amplifier in order to operate. The earphone or speaker output of a computer need a active speaker (with integrated amplification) . [ JESUS  Feb 26, 2017 ]
    No they will not. They would need an amp. There are small amps the size of a male's hand out there for around 25-30 dollars that can work. You have to search for them.They are around 20 or 30 watts per channel. You will need at least 20 watts. You will have to run regular speaker wire to the amp, a pair of simple RCA jacks and a "Y" adapter to the computer jack.( cheap and simple) You can use any receiver to do this. Just plug into the CD input. You can also buy good powered speakers for computers. Hope this helps,You have a great day [ Antoine E.  Feb 26, 2017 ]
    No, you need speaker wire to connect them directly to your amplifier. [ Brian  Feb 25, 2017 ]
    Not easily. These speakers have traditional terminals meant to be used with AV or Stereo Receivers. You would have to manufacture a cable & hope your computer has the proper power output. You would be better off purchasing a pair of speakers specifically designed for use with a Computer or Laptop. [ David  Feb 24, 2017 ]
    I suspect they could but I have no idea how to do it. [ David  Feb 24, 2017 ]
    No, you must use regular speaker cables. [ James  Feb 24, 2017 ]
    No. this is a passive speakers and need a amplifier in order to operate. The earphone or audio output of a HDTV need a Receiver to connect the Polk TSi-100 speaker . [ JESUS  Apr 03, 2017 ]
    No, these are not self powered speakers. You need a receiver. It can be a small on though [ Badrinarayanan  Jan 28, 2016 ]
    Hi their, you will need a separate receiver. [ Antoine E.  Jan 27, 2016 ]
    You will not be able to connect this directly to a TV set without a seperate receiver. [ EARL  Jan 27, 2016 ]
