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: 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
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.
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. 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
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.
