Description
Dual 18-inch active 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 new generation of powered line arrays and subwoofers addresses the growing need for scalable small and medium-sized professional sound reinforcement solutions for rental companies, fixed installations, and musicians seeking the ultimate combination of performance and portability.
The SRX928S is a dual 18-inch active subwoofer designed to complement SRX900 full-range sound reinforcement systems. The subwoofer features two JBL 2279-1 18-inch woofers, featuring Differential Drive® – JBL’s dual voice coil, dual gap technology – for better heat dissipation, lower power compression, and wider dynamic range than conventional single-coil designs. Built-in DSP and amplification provide a plug-and-play experience while ensuring consistency and optimum performance anywhere in the world.
The SRX928S features a large central low-frequency port design that improves airflow and reduces audible turbulence, even at high output levels. A new, full-featured software suite gives users control over the system across multiple platforms, including Windows, macOS, and iPad OS. Read more about JBL Performance here.
