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:
Each speaker features a polymer composite woofer for smooth wide-range
response with low distortion. For
high performance durability, each woofer uses a butyl rubber surround.
Silk/Polymer Tweeters: Each
speaker has a 1" silk/polymer dome tweeter that provides clear, detailed
highs. Each tweeter uses a heat
sink on the Neodymium magnet for superior heat dissipation, power handling and
Acoustically Inert Cabinets:
Each speaker cabinet features all-MDF construction with extensive internal
bracings that virtually eliminate sound-muddying resonance.
Power Port Venting System: Each
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, each speaker has a front-firing
port that is tuned to suppress the internal cabinet resonance, resulting in
smooth, natural midrange reproduction.
Anti-Diffraction Grilles: The
floating anti-diffraction grilles minimize grille diffraction for spacious,
Dual 5-Way Binding
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
Mounting: The Power
Port back plate on each speaker has a keyhole slot, allowing the speaker to be
mounted on the wall using optional hardware.
speakers are magnetically shielded, allowing you to place them near your
television without distorting the picture.
Frequency Response Note:
The overall frequency response is 50Hz-27kHz and the -3dB frequency response is
