Polk Audio Vanishing Series 900-LS In-Ceiling Speaker (Each)

Product Description 900-LS – Overview Mount your woofer behind your main driver array, and suddenly you’re able to extend a speaker’s dynamic range into previously unexplored areas! Especially for a built-in in-ceiling speaker. The 900-LS delivers surprisingly broad coverage and bold, full-range audio performance. Big enough to use as stealth mains, stealthy enough to use as hidden surrounds or alternate-zone speakers. Audiophile Performance, Cutting-Edge Stealth Design 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.
