In-Wall Subwoofer System with Single 13.5-inch Subwoofer, 1000 watts


The same minds that engineered JL Audio’s reference-grade Fathom® and Gotham® powered subwoofers have created an amazing in-wall subwoofer solution, centered on an innovative, thin-line driver with groundbreaking technologies.

Housing this exotic driver is a critically engineered enclosure with a unique floating mount design to minimize wall excitation. The enclosure features extensive architectural features aimed at improving rigidity while keeping a very low profile and minimal wall thickness.

A paintable, fine steel-mesh grille, also designed to control vibration, is included for each enclosure in a system.

The IWSv2-SYS-113 is driven by a rack-mountable, purpose-tuned amplifier, capable of delivering up to 1 kW of clean power, and armed with serious processing features, including our acclaimed Digital Automatic Room Optimization system.

There is no need to lower your expectations when selecting this remarkable in-wall solution... it's a real Fathom®.

The IWSv2-SYS-113 is available to fit a variety of 2" x 4" and 2" x 6" wall studs. Consult your Authorized JL Audio Dealer for specific application information.
