8-inch In-Ceiling Subwoofer
In-Ceiling Subwoofer System with Single 8-inch Subwoofer Driver, 300 watts
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.
Each 8-inch Fathom® ICS system is driven by a rack-mountable amplifier with up to 600 watts of clean power, programmed specifically for each system, and capable of driving up to two enclosures. A complete set of Fathom® signal processing features is also onboard, including our powerful, 18-band Digital Automatic Room Optimization (D.A.R.O.) system, and high-pass crossover outputs, all accessible via an easy-to-use, menu-driven interface and LCD display. Note: D.A.R.O. functionality requires optional calibration microphone (sold separately).
The ICS-108 System fits 2" x 6" ceiling joists or larger, with assembled joists ranging from 16-inches to 25 1/2-inches on center. Consult your Authorized JL Audio Dealer for specific application information.
