In-Wall Subwoofer System with Single 8-inch Subwoofer, 300 watts


Born from the same groundbreaking technologies used to develop our free-standing powered subwoofers, the Fathom® IWS in-wall subwoofer systems deliver remarkable bass performance, while remaining largely concealed within most home audio/theater environments.

The 8-inch Fathom® IWS systems are smaller and easier to integrate than our larger in-wall Fathoms, fitting in all standard, 16-inch, on-center stud openings, and operating through very small grilles. These grilles accommodate all common drywall thicknesses, and can be easily painted to match the wall.

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® IWS products.

Each 8-inch Fathom® IWS system is powered by a rack-mountable amplifier, capable of generating up to 600 watts of clean power and can drive 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, all managed via an easy-to-use, menu-driven interface and LCD display. Note: D.A.R.O. functionality requires optional calibration microphone (sold separately).

The IWS-108 System fits 2" x 4" wall studs or larger. Consult your Authorized JL Audio Dealer for specific application information.

Enclosure Finish: Flat Black (hidden from view when installed)

Grille finish: Primer White (paintable)

Enclosure Construction: CNC-Cut Birch Plywood



Technology

Digital Automatic Room Optimization (D.A.R.O.)

JL Audio's exclusive D.A.R.O. technology uses a powerful on-board DSP to automatically optimize the subwoofer's in-room frequency response. This leads to a superb listening experience, no matter where the subwoofer is placed.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
