Designed for powerful performance

JBL's STX818S passive subwoofer packs an 18" driver with 2,000-watts RMS power handling for maximum sonic quality. JBL's Super Vented Gap woofer technology helps extend the frequency response, so you'll get ultra-low bass that retains punch and impact. The high power rating gives the STX818S the needed headroom to reproduce your sound with exceptional richness and focus, with virtually distortion even when pushed hard.

If you need a tour-quality subwoofer that can take abuse, you'll appreciate the STX818S's design. You get multi-ply birch/poplar construction, coated with DuraFlex for maximum protection.
