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.

Driver Technology
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 5.25" 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 50Hz-27kHz and the -3dB frequency response is
60-26kHz.
Enclosure Design
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
"right" channel.
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,
3-dimensional imaging.
Port: On the side with only a
tweeter, there is a single port tube opening for increased and extended bass
response.
Connections
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.
Mounting Options
Dipole/Bipole
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.
Wall Mounting: 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"
wood screws.
