Get to know this product.

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 a purpose-engineered, thin-line driver with patented technology.

In-Wall Subwoofer System With Single 13.5" Subwoofer Driver, 1000 Watts 

  • 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 IWS System One 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 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 IWS System One 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.
