Features

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.

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.

5-Way Binding Posts: The 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.

Magnetically Shielded: Because the speaker is magnetically shielded, it can be safely placed directly on or near video sources without creating a distorted picture.

Recommended 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.

Note

Frequency Response: The overall frequency response is 55Hz-22kHz. The -3dB frequency response is 60Hz-20kHz.

Manual Correction

Speaker Impedance: The manual incorrectly lists the speaker's nominal impedance as 4 ohms. The impedance is 8 ohms.
