JBL SRX918S 18” Active Subwoofer

The SRX918S is a single 18-inch powered subwoofer designed to complement the SRX900 Series full-range sound reinforcement systems. The subwoofer houses an 18-inch JBL 2279-1 woofer featuring Differential Drive®, JBL’s signature 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 SRX918S incorporates a large low-frequency 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.
