JBL 18-inch Powered Flyable Subwoofer

AV Technology InfoComm 2025 Best of Show Award

The SRX918SF is a powered, flyable single 18-inch subwoofer designed to be deployed in suspended or ground-stacked configurations to complement SRX900 Series full-range systems. The integrated three-point rigging system in the SRX918SF allows units to be suspended in standalone arrays or in combination with SRX910LA cabinets in mixed-array configurations.

The subwoofer houses a JBL 2279-1 18-inch woofer featuring Differential Drive® – JBL’s dual voice coil, dual gap technology – to deliver better heat dissipation, lower power compression, and wider dynamic range than conventional single-coil designs. Built-in DSP and amplification offer a plug-and-play experience while providing consistency and optimum performance anywhere in the world.

The SRX918SF incorporates a large low-frequency port design that improves airflow and reduces audible turbulence, even at high output levels. A reinforced 18 mm birch plywood cabinet ensures enhanced strength and durability. A full-featured software package gives users complete control of the system on various platforms, including Windows, macOS, and iPad OS.
