18-inch Powered Subwoofer

The SRX900 Series embodies the advanced performance principles that drive JBL's development of audio products that make a real difference in the world of professional audio. This next-generation family of powered line arrays and subwoofers addresses the growing need for scalable small and medium-format professional sound-reinforcement solutions for rental companies, fixed installations and musicians seeking the ultimate combination of performance and portability.

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. A new, full-featured software package gives users control of the system on various platforms, including Windows, macOS, and iPad OS.Learn more about JBL Performance here.
