Patented Polk Audio technology and construction techniques produce powerful, deep bass performance, especially when you need it most.
Patented bass venting design smoothly transitions air flow, eliminating turbulence and distortion, for deeper, more efficient bass impact.
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 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.
If your loudspeakers need to be installed closer than 2 feet from side walls, the proximity of the surface can result in a response bump between 50 and 200Hz. This can create a ‘boomy' sound. The Vanishing wall distance toggle switch is a custom audio control that adjusts the crossover to flatten response and tune out boomness, without sacrificing deep bass response.
