Our take on the Polk Audio TSi300

Music lovers and movie buffs alike will enjoy the smooth, clean sound of the Polk TSi300. Its silk tweeter delivers sparkling highs, while two polycarbonate woofers churn out accurate mids and lows. The braced MDF 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 TSi300 for even better performance — a rare feature for a speaker in this price range.

A woodgrain vinyl finish gives the TSi300 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 authoritative 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 two 5.25" bi-laminate composite dynamic balance drivers which are light and stiff for deep bass response and low distortion. 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 35Hz-25kHz and the -3dB frequency response is 47-24kHz.

    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.


    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.

    Adviser recommended based on planned use, listening preference, and room size [ MARK C  Nov 22, 2016 ]
    I have moved and bought a new denon receiver. While setting up my system I realized that one of my front speakers had gone bad. I had originally intended to wait and save up to buy some fairly high end speakers but now I needed to get speakers on a budget. These fit the price point and the reviews are very positive. I'm sure they will be a big step up from my previous speakers. [ Joel  Oct 03, 2016 ]
    Liked the Cherry color. Compatible with other colors in room. [ Jackie  Mar 29, 2016 ]
    I was going for the 'level up' in the scratch and dent, but they only had a single speaker in stock. The TSi300 was on sale, so I figured I check them out instead. [ Rebecca  Mar 02, 2016 ]

    6 questions already asked

    Although I've never used Polk speakers, I am using premiere acoustics speakers and I believe you will get better results with Polk.. [ julian  Feb 17, 2017 ]
    Yes they are. However I would go with the TSI400 or even better yet the TSI400 you can still find them oN line cheep. [ BRAD  Feb 17, 2017 ]
    The Polk Audio would be a good match with the Onkyo receiver.I have a bigger model polk towers hooked up to mine and they sound great.If you are using to play movies,make sure to get a good center channel speaker too. [ Guest  Feb 17, 2017 ]
    With jumpers [ WILLIAM B  Aug 29, 2016 ]
    There are two sets of red & black connectors. You use just one set for a normal connection, and for bi-amping you use all four after removing the metal jumpers. [ Tom  Aug 27, 2016 ]

    The price is listed each - so it will be for just one speaker. [ Jeff  Nov 26, 2013 ]  Staff
    During your planning make sure to consider how high the tv would be if you placed it above the speaker. Avoid placing the tv so high your neck so your neck starts to ache from looking up for a whole movie. I wouldn't recommend placing the speaker on its side because of its design.
