Description

The Polk Audio 255c-LS is a high-performance in-wall center channel speaker designed to deliver powerful, room-filling sound while remaining virtually invisible. With Polk’s Vanishing LS Series design, this speaker blends seamlessly into your space, providing clear, detailed dialogue and deep bass without taking up floor or shelf space.

Equipped with dual 5.25″ Dynamic Balance® aerated polypropylene cone mid/woofers, the 255c-LS delivers accurate mids and deep, impactful bass. Polk’s PowerPort® bass venting technology enhances low-end response, reducing distortion and providing a rich, immersive listening experience. The 1″ Ring Radiator Tweeter ensures detailed highs and precise imaging, making every movie scene and musical note come to life.

To optimize performance in different acoustic environments, the wall distance toggle switch helps compensate for boominess when placed near walls, and the tweeter attenuation switch fine-tunes highs in rooms with reflective surfaces.

The magnetic Sheer-Grille™ is nearly invisible and paintable to match your décor, ensuring the speaker integrates seamlessly into your space.
