JL Audio IWS sys-108

In-wall powered subwoofer System

The JL Audio IWS Sys-108 is a concealed in-wall subwoofer system which delivers remarkable bass performance for most home audio/theatre environments.

The 8-inch IWS systems are smaller and easier to integrate than their larger in-wall Fathoms system.  They fit in all standard, 16-inch, on-centre 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 IWS-108 System fits 2″ x 4″ wall studs or larger.
