2 x 8" in-ceiling powered subwoofer with an Amplifier/Processor system
Created from the same innovative technologies used to develop our free-standing powered subwoofers, the Fathom® ICS in-ceiling subwoofer systems are engineered to deliver outstanding bass performance, with nearly unlimited placement freedom.
Purpose-built to disappear into the ceilings of most home audio/theater environments, the 8-inch Fathom® ICS systems are designed to fit 2" x 6" or larger ceiling joists and a wide range of assembled joist widths, while operating through very small grilles. The grille’s clever design accommodates all common drywall thicknesses and can be easily painted to match a room’s decor.
The subwoofer enclosures utilize extensive architectural features aimed at improving rigidity while keeping a very low profile and minimal wall thickness. A unique port design vents through a slot located at the perimeter of the driver mount to enhance efficiency and low-bass output. Inside the enclosure is a long-excursion, 8-inch thin-line woofer, built to exacting standards by JL Audio for the Fathom® ICS products.
