Powerful and Accurate Low End with a Cinematic Flair

Engineered for powerful, yet accurate, low-frequency response, the JBL Synthesis SSW-4 installs seamlessly in a standard 2 x 4 wood-frame wall. This robust in-wall sub features dual 8-inch low-profile, metal-cone woofers mounted in a braced molded baffle with an integrated MDF enclosure. Able to deliver world-class low end in small- to medium-sized rooms, the SSW-4 boasts gold-plated, spring-loaded binding post input terminals for lock-tight connections. Finally, a zero-bezel, magnetically attached paintable grille ensures flawless aesthetics that match any décor. Searching for a no-compromise passive subwoofer with reference-grade dynamics, unerring accuracy, and maximum cinematic impact? The SSW-4 certainly ticks all those boxes, making it a high-impact addition to any JBL Synthesis installation.
