More boom in your ceiling – JL Audio announce their new 8-inch version in-wall Fathom subwoofer with added enclosure option for in-ceiling use. "This model has a very small, low-profile grille that will please customers looking for a visually unobtrusive solution that delivers true JL Audio sub-bass performance." 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 by JL Audio for this product. Each 8-inch Fathom IWS and ICS system is driven by a rack-mountable amplifier with up to 600 watts of power programmed specifically for each system. A complete set of Fathom signal processing features include a powerful 18-band digital automatic room optimization system and high-pass crossover outputs all accessible via an easy-to-use, menu-driven interface and LCD display.
