Product Details

The Polk Audio 620-RT in-wall speaker system uses 6.5-inch woofers and 0.75-inch pivoting silk-polymer dome tweeters for quality sound. Featuring a patented port design, the Polk Audio speaker system delivers full-range sound with no sacrifices in quality. The design of the in-wall speaker system includes magnetically mounted speaker grilles that fit flush in the ceiling, keeping components out of sight, but filling the room with powerful audio. The Polk Audio 620-RT features a frequency response range of 52 Hz to 23 kHz (+/-3 dB) and is supported with infinite baffle tuning for improved bass response, capable of handling up to 100 watts. The Polk Audio speaker system is equipped with sensitivity of 89 dB, and allows for 8-ohm impedance to keep things smooth. Simple and quick to install, the Polk Audio speaker system requires a cutout diameter of 8.2 inches and a mounting depth of 4.3 inches to fit into the wall.
