JBL Professional SRX928S Dual 18" Powered Subwoofer, Black

Deliver authoritative, studio-grade low frequency performance for large venues, touring rigs, and critical AV/security control rooms with the JBL Professional SRX928S dual 18-inch powered subwoofer. Engineered to anchor full-range systems, the SRX928S uses two JBL 2279-1 woofers and Differential Drive® technology to reduce power compression and extend dynamic range so your content retains punch and clarity even at high SPLs. With 1100W RMS output and a low-frequency response down to 31 Hz, it beefs up music, speech intelligibility and paging in monitoring or surveillance operations where low-end presence matters.

The SRX928S combines a passively cooled Class D amplifier, user-controllable DSP and LevelMax limiting to protect transducers while maintaining consistent performance. Network-ready features — dual Neutrik etherCON ports and HARMAN HControl compatibility — let integrators manage and monitor systems across AV and security networks. Built for the road but refined for installations, its reinforced plywood enclosure and rear-panel LCD speed setup and serviceability. Add the JBL SRX928S to your AV, security or monitoring stack to get dependable, high-impact bass—contact sales or order now to specify it into your next project.
