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, the center-channel speakers produces sound that is open, spacious and
clear, even when driven by modestly-powered amplifiers and receivers.
Bi-Laminate Composite Woofers: The center-channel speaker features
two 5.25" bi-laminate composite (organic fiber) dynamic balance drivers which is 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 and durability, each woofer uses a butyl rubber
Silk dome Tweeters: The center-channel
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.
The overall frequency response is 53Hz-25kHz and the -3dB frequency response is
Quality Built Cabinets: The
TSi speaker cabinets are extensively braced MDF with ¾" thick
baffles and have pewter accents, piano black end caps, and a removable black
grille. 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 speaker 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. The TSi center-channel speaker
uses a rear-firing port.
5-Way Binding Posts: The center-channel speaker has a pair of
gold-plated 5-way binding posts for a superior connection to your AV receiver.
center-channel speaker should be placed directly above or below your television.
The TSi series center-channel speaker is magnetically shielded for safe
placement near your TV or video monitor.
Rubber Feet: The center-channel speaker comes with four self-adhesive rubber feet so
it will sit securely on your stand or shelf.
