The SRX928S is a dual 18-inch active subwoofer designed to complement SRX900 full-range sound reinforcement systems. The subwoofer houses two JBL 2279-1 18-inch woofers, 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 SRX928S incorporates a large central 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.

This family of powered line arrays and subwoofers addresses the growing need for affordable, scalable small and medium-format professional sound-reinforcement solutions. It’s ideal for rental companies, fixed installations and musicians seeking the ultimate combination of performance and portability.

The SRX900 Series’ outstanding sonic performance is based on time-tested JBL technologies.

SRX900’s cabinet architecture is thoughtfully engineered for easy handling, fast rigging, minimal space displacement and streamlined transport.

The family includes dual 6.5-inch and dual 10-inch powered line array loudspeakers and 18-inch and dual 18-inch powered subwoofers. Because these systems are scalable and affordable, users can start with a small investment and expand over time. All SRX900 models work seamlessly with other JBL touring PA systems.
