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.
