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. The switch for selecting Dipole or Bipole operation is located in
the terminal cup on each speaker. One of the speakers is specifically designed
for the "left" channel and the other for the "right"
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
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.
Port: On the side with only a
tweeter, there is a single port tube opening for increased and extended bass
Acoustically Inert Cabinets:
Each speaker cabinet features all-MDF construction with internal bracings that
virtually eliminate sound-muddying resonance.
Anti-Diffraction Grilles: The
floating anti-diffraction grilles minimize grille diffraction for spacious,
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, located in the terminal cup, 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.
Mounting: The bracket
on the back of each speaker has two keyhole slots, allowing the speaker to be
mounted on the wall using optional hardware.
Frequency Response Note: The
overall frequency response is 50Hz-27kHz and the -3dB frequency response is 60-26kHz.
