Dynamic Balance®

Patented Polk Audio technology and construction techniques produce powerful, deep bass performance, especially when you need it most.

Power Port®

Patented bass venting design smoothly transitions air flow, eliminating turbulence and distortion, for deeper, more efficient bass impact.

Sheer-Grille™

Vanishing® Series built-in speakers feature Polk's exclusive wafer-thin Sheer-Grille™, a magnetically-secured grille that protrudes only 7mm from its surroundings. Sheer-Grilles have nearly transparent, ultra-small perfs, and are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms.

Reflective Room Compensation

Reflective surfaces in rooms can make sound brighter and cause image distortion. Engaging the Vanishing reflective room compensation feature lowers the tweeter level to compensate for reflective surfaces. Vanishing reflective room compensation is a custom audio control that cuts the level only in the 4-5kHz range, exactly where reflectivity destroys sound quality.

Distance Toggle

Crossover adjustments flatten response bumps caused by nearby walls, reducing "boominess" for more lifelike sound from any position.

Please note: Not suitable for environments where the air has a high salt content, such as coastal areas. For more info, please contact our helpful staff.
