Enjoy extraordinary audio performance for your movies, music and TV shows with the Polk Vanishing Series 255c-LS. It disappears into your wall yet delivers impactful, room-filling sound for movies, music and TV shows; satisfying audiophiles and homeowners alike. Equipped with dual 5.25″ Dynamic Balance Midrange Drivers for a consistent frequency response and a 1″ Ring-Radiator Tweeter for incredible imaging; these Polk Audio Speakers feature patented PowerPort Bass Technology that adds deep, rumbling bass while minimizing unwanted resonances. On the front panel, it has a reflective room compensation control switch that digitally compensates for harsh reflective surfaces, such as smooth walls, glass windows, and hardwood floors for a smooth audio quality. The center channel can be paired with the Vanishing LS Series in-wall stereo speakers and Polk’s traditional floor-standing and bookshelf speakers, allowing you to build a complete home theater system. The rotating cam stabilizing system in these wired speakers offer a quick and easy installation, and the paintable wafer-thin Sheer-Grille makes the speaker virtually indistinguishable from its surrounding. The speaker can also be mounted into new or existing constructions using the optional in-wall mounting brackets.
