Premium Bass, Small Space, No Face
Polk’s patented PowerPort bass venting system greatly enhances the smooth low-end response in this easy-to-place, single-woofer in-wall speaker. Recommended for use as left and right front channel speakers, stealth side or rear surround speakers in an RTi theater system setup, or for superior dynamics in practically invisible multi-zone music systems. Virtually-flush mounting with a minimal-flange design means this speaker never attracts attention by its looks, only by its performance.
Vanishing Series built-in speakers feature our 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. Painted to match your decor, Vanishing Series built-in speakers are virtually indistinguishable from their surroundings.
Reflective surfaces in rooms can make sound brighter and cause image distortion. Engaging the Vanishing reflective room compensation feature (by selecting the low setting) 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. Outside this narrow 1kHz band, the tweeter retains its detailed and accurate high frequency response, for no loss of realistic musical details.
