The Polk Audio V80 is a high-performance in-ceiling speaker designed for discreet installation, featuring an 8-inch Dynamic Balance polypropylene cone for clear midrange and punchy bass, and a 1-inch aimable silk dome tweeter for crisp, clear imaging. It uses Polk's "Vanishing" design with a magnetically attached, wafer-thin Sheer-Grille that blends into the ceiling, and the patented Rotating Cam System provides secure, vibration-free mounting. The speaker is Dolby Atmos compatible and can be used for both home theater and whole-house audio.
