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 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: 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.
The overall frequency response is 35Hz-25kHz and the -3dB frequency response is
Quality Built Cabinets: The
TSi speaker cabinet is extensively braced from 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.
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.
