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 7" polymer composite woofers. Two 7" woofers have the surface area of a single large woofer with the low mass and acceleration of small woofers, resulting in tighter, more accurate bass response. Each woofer uses a butyl rubber surround.

Polymer Composite Midranges:

• The speaker has one 6-1/2" polymer composite midranges for smooth wide-range response with low distortion.
• For high performance durability, the midrange uses a butyl rubber surround.

Silk/Polymer Tweeter:

• The speaker has a single 1" silk/polymer dome tweeter that provides clear, detailed highs.
• The tweeter features mylar bypass capacitors in the crossovers to extend high frequency response and improve detail and transparency.
• The tweeter also features low viscosity ferro-fluid cooling with a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.

Magnetically Shielded:

• The speakers are magnetically shielded, allowing you to place them near your television without distorting the picture.

Enclosure Design

Damped Asymmetric Hex Laminate (DAHLI) Cabinet Design:

• All-MDF construction with massive asymmetric cabinet bracing ensures a resonance-free enclosure for accurate sound.
• The asymmetric design is made from a 6-layer laminate with 5 viscous layers to create the optimal shear damping (OSD) system.
• The elegant styling aside, curved cabinets not only result in a stronger, more rigid and acoustically inert enclosure, but the curved walls also produce less audible coloration from panel resonances.

Power Port Venting System:

• The speaker has a rear-firing Power Port venting system built into its back plate for precise deep bass response.
• This venting system allows air velocity to slow gradually, vastly reducing air turbulence, and delivering greater bass efficiency than conventional ports.

Acoustic Resonance Control (ARC):

• Internal cabinet resonance can impart a "thick" character to voices.
• Polk's patented Acoustic Resonance Control port system overcomes this problem.
• In addition to the Power Port venting system, each speaker has a front-firing port that is tuned to suppress the internal cabinet resonance, resulting in smooth, natural midrange reproduction.

Anti-Diffraction Grilles:

• The floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.

Connections

Dual 5-Way Binding Posts:

• The speaker has two sets of gold-plated 5-way binding posts connected by gold-plated jumpers.
• Using the dual 5-way binding posts, you can bi-amp or bi-wire the speakers.

Mounting Options

Adjustable Leveling Spike Feet:

• The adjustable leveling spike feet that can be screwed onto the bottom of the speaker's attached base provide stability on any type of flooring.
• The spike feet adds approximately 0.875" to the speaker's overall height when screwed all the way in.

Specifications & Dimensions

Frequency Response:

• The overall frequency response is 20Hz-27kHz and the -3dB frequency response is 35-26kHz.

Width:

• The main body of the speaker is 8.6875" wide but the speakers attached feet extend beyond each side of the speaker, giving the speaker and overall width of 10.6875".
