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.

Features
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.
Polymer Composite Woofers: The
speaker features two 6-1/2" polymer composite woofers for smooth wide-range
response with low distortion. For high performance durability, each woofer uses
a butyl rubber surround.
Silk/Polymer Tweeter: The
speaker has a 1" silk/polymer dome tweeter that provides clear, detailed
highs. The tweeter uses a heat sink on the Neodymium magnet for superior heat
dissipation, power handling and reliability.
Acoustically Inert Cabinet: The
speaker cabinet features all-MDF construction with extensive internal bracings
that virtually eliminate sound-muddying resonance.
Power Port Venting System: The
speaker has a rear-firing Power Port venting system built into its back plate
for precise deep bass response. This venting system allows air velocity
to slow gradually, vastly reducing air turbulence, and delivering greater bass
efficiency than conventional ports.
Acoustic Resonance Control (ARC):
Internal cabinet resonance can impart a "thick" character to voices.
Polk's patented Acoustic Resonance Control port system overcomes this problem.
In addition to the Power Port venting system, the speaker has a front-firing
port that is tuned to suppress the internal cabinet resonance, resulting in
smooth, natural midrange reproduction.
Anti-Diffraction Grille: The
floating anti-diffraction grille minimizes grille diffraction for spacious,
3-dimensional imaging.
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 speaker.
Magnetically
Shielded: The speaker
is magnetically shielded, allowing you to place it near your television without
distorting the picture.
Adjustable Leveling Spike Feet:
The adjustable leveling spike feet mounted on the stabilizer bars provide
stability on any type of flooring.
Notes
Frequency Response Note: The
overall frequency response is 30Hz-27kHz and the -3dB frequency response is 40-26kHz.
Dimension Note: The main body
of the speaker is 7.767" wide. The stabilizer bars extend beyond each side
of the speaker, giving the speaker an overall width of 10.953".
