ICS11 Ceiling Subwoofer

Ceiling passive subwoofer with a 10" long excursion graphite woofer and a power handling capacity of 175 watts. Designed to be used with the Proficient M3 Amp/Crossover.

The stealth subwoofer

Subwoofers. We love what they do for movies and music but hate the way they look. Proficient has the answer: the ICS11 in-wall subwoofer. The ICS11 mounts flush like an in-wall speaker. How can we get its big 10-inch pulp-fiber woofer to fit in a 3½-inch-deep wall cavity? By moving the powerful neodymium magnet to the front.

To power the ICS11, use our M3 subwoofer amp. The M3 goes in your equipment rack and connects with in-wall speaker cable. No matter how you set it up, the ICS11's 36 Hz response and 250-watt power handling ensure you'll get great bass. Includes Thin-Bezel Grilles held by Neo Magnets.
