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.
