Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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.
