JBL SRX928S Dual 18" Active Subwoofer

The SRX928S is a dual 18-inch powered subwoofer designed to complement the SRX900 full-range sound reinforcement systems. The subwoofer houses two 18-inch JBL 2279-1 woofers, which feature Differential Drive, JBL’s dual voice coil, double-gap technology, to deliver improved heat dissipation, lower power compression, and a wider dynamic range than conventional single-coil designs. Built-in DSP and amplification deliver a plug-and-play experience, while delivering consistency and optimal performance anywhere in the world. The SRX928S incorporates a large, low-frequency center-port design that improves airflow and reduces audible turbulence, even at high output levels. A new, full-featured software suite gives users control of the system across multiple platforms, including Windows, macOS, and iPad OS.
