About the JBL Synthesis SSW-3

Part of the JBL Synthesis Subwoofer series, the SSW-3 is an ultra-high-performance passive in-wall subwoofer acoustically designed to complement any of the JBL Synthesis Custom Loudspeakers (SCL series) as part of a complete JBL Synthesis solution.

High Performance Sub

The SSW-3 features dual 10-inch (250mm) cast-frame, composite cone woofers, each with large 2.5-inch (63mm) voice coils for total system power handling of 600W RMS. A compression-molded baffle with extensive structural ribbing provides a rigid, low-resonance mounting surface for the transducers. The baffle assembly attaches to the included in-wall enclosure resulting in a completely sealed acoustic suspension design. The in-wall enclosure is constructed of 0.75-inch (19mm) MDF with substantial internal bracing and features rubber isolation mounting points to minimize sonic intrusion into the wall structure. The combined assembly is designed to fit standard 2x6-inch wood frame construction. The backbox and baffle ship together.

Discrete In-wall Installation

Designed for discrete in-wall installation, the SSW-3 includes a paintable zero-bezel, magnetically attached grille, or it may be used without the grille when located behind acoustically transparent fabric panels. The SSW-3 delivers powerful, dynamic, and accurate bass response in medium to large-sized rooms.
