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: Each speaker features a 6.5"
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 dual 1" silk/polymer
dome tweeters that provide clear, detailed highs and spacious surround effects.
Each tweeter uses a heat sink on the Neodymium magnet for superior heat
dissipation, power handling and reliability.
Frequency Response: The overall frequency response is
45Hz-27kHz and the -3dB frequency response is 55-26kHz.
Enclosure: Each enclosure has a triangular
shape with the speaker faces angled at 45 degrees. One face has a tweeter and a
woofer, while the other face has a tweeter and port tube opening. A switch for
selecting Dipole or Bipole operation is located on the rear of the speaker above
the speaker's 5-way binding post speaker terminals. One of the speakers is specifically
designed for the "left" channel and the other for the
Acoustically Inert Cabinets:
Each speaker cabinet features all-MDF construction with internal bracings that
virtually eliminate sound-muddying resonance. The speakers are finished in
either a black or white laminate finish.
Anti-Diffraction Grilles: The
floating anti-diffraction grilles minimize grille diffraction for spacious,
Port: On the side with only a
tweeter, there is a single port tube opening for increased and extended bass
5-Way Binding Posts:
The gold-plated 5-way binding posts will accept bare wire, pin
connectors, spade connectors, banana plugs, and dual banana plugs.
Switch: There is a switch that allows each speaker to be used as a Dipole (out of phase) or Bipole
(in phase) speaker. If you're mounting the speakers on the side walls in line
with your listening position, the dipole mode will create a diffuse, ambient
soundfield. If you're placing them behind your position, the bipole mode fires
the drivers in phase to flood your room with surround sound. When used with a
Dolby Digital system, the surround speaker setting should be set to small.
The bracket on the back of each speaker has two keyhole
slots, allowing the speaker to be mounted on the wall using the supplied 2-1/2"
