About the Polk Audio TSi400
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.

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.

Clear sounding speakers at all ranges. The bass is not over the top, (sometimes I wish it was), and keeps it clear at much higher levels. For the price excellent speakers and the only issue would be the slight lack of bass, but I guess a sub-woofer would take care of that.
