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
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 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: 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
43Hz-25kHz and the -3dB frequency response is 50-24kHz.
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
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.
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.
