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.
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.
Composite Woofer: The speaker
uses a 5-1/4" composite Dynamic Balance woofer for clean midrange and deep,
accurate bass. For a smoother response and improved durability, the woofer uses
a rubber surround.
Silk/Polymer Tweeters: The
improved Dynamic Balance silk/polymer tweeter provides clear, detailed highs.
Bass Reflex: There is a
single port tube opening on the front of the speaker
for increased and extended bass response.
Posts: The 5-way
binding posts will accept bare wire, pin connectors, spade connectors, banana
plugs, and dual banana plugs.
Shielded: Because the
speaker is magnetically shielded, it can be safely placed directly on or near
video sources without creating a distorted picture.
Center Channel Mode: Polk
recommends using this speaker in the normal (small) center channel mode when
used with either Dolby Pro Logic or Dolby Digital/DTS . The crossover is a 2nd
order low-pass and high-pass filter at 3.6kHz.
Frequency Response: The overall
frequency response is 55Hz-22kHz. The -3dB frequency response is 60Hz-20kHz.
Speaker Impedance: The manual
incorrectly lists the speaker's nominal impedance as 4 ohms. The impedance is 8
