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: The speaker features two 5-1/4" polymer composite woofers for smooth wide-range response with low distortion. For high performance durability, each woofer uses a butyl rubber surround and an acoustically inert stamped driver basket.

Silk/Polymer Tweeter: The speaker has a 1" silk/polymer dome tweeter that provides clear, detailed highs. The tweeter uses a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.

Frequency Response Note: The overall frequency response is 55Hz-27kHz and the -3dB frequency response is 65-25kHz.

Enclosure Design

Acoustically Inert Cabinet: The speaker cabinet features all-MDF construction with extensive internal bracings that virtually eliminate sound-muddying resonance.

Port: There is a single port tube opening on the front of the speaker for increased and extended bass response.

Anti-Diffraction Grille: The floating anti-diffraction grille minimizes grille diffraction for spacious, 3-dimensional imaging.

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

Reversible Design: If the speaker must be positioned below ear level, you can turn the cabinet upside down, allowing the drivers to fire upward.

Magnetically Shielded: The speaker is magnetically shielded, allowing you to place it on your television without distorting the picture.
