The SRX918S is a single 18-inch active subwoofer designed to complement SRX900 Series full-range sound reinforcement systems.
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 SRX918S
incorporates a large low frequency port design that improves airflow and reduces audible turbulence, even at high output levels.
