About the Synthesis SSW-1

Incredibly low-noise performance

The SSW-1 features dual 15-inch (380mm) cast-frame, black advanced Aluminum Matrix cone woofers, each with a massive 6-inch (152mm) voice coil for total system power handling of 5000 WRMS. Cabinet tuning is via dual front-firing tuned ports featuring JBL’s patented Slipstream™ contouring for incredibly low-noise performance. The robust enclosure is constructed from 1-inch (25mm) MDF with extensive internal bracing and includes a steel-frame, magnetically attached cloth grille. The configuration of the enclosure allows it to be positioned vertically or laid on its side horizontally for tremendous placement flexibility in applications including built-in, behind the screen, or in-room. The SSW-1 delivers powerful, dynamic, and accurate bass response in large rooms.
