JBL SRX928S 2500-watt 2 x 18-inch Powered Subwoofer

JBL SRX928S 2500-watt 2 x 18-inch Powered Subwoofer

The SRX928S powered subwoofer brings double the low-end thump to JBL’s SRX900 sound system! Two 18-inch powered transducers boast dual voice coil, dual gap technology that deliver a massive bass response all the way down to 31Hz. JBL has upgraded the SRX928S with improved heat dissipation, lower power compression, and a tremendous dynamic range that’s designed to excel with any of JBL’s other tour sound products. Plus, the integrated power and a wide range of DSP effects make the SRX928S an excellent choice for those seeking a plug-and-play solution for their low-end needs. The live sound engineers love the amount of control JBL built into the SRX900 series — a rear-panel LCD makes switching up your settings simple. And if you need control from a distance, the SRX928S is both Ethernet and Wi-Fi compatible to connect to JBL’s all-encompassing software suite. Looking to bolster your sound system with some ground-shaking bass power? The SRX928S fits the bill.

High-performance dual 18-inch drivers

JBL's SRX928S is powered by a pair of 2279-1 drivers, boasting an 18-inch construction for a clear and articulate bass response all the way down to 31Hz! The 2279-1 utilizes a dual 3-inch voice coil design that, when paired with JBL’s innovative Differential Drive technology, offers an incredible amount of floor-shaking power, clarity, and sensitivity in a highly portable package. What’s more, 900-series subwoofers can be operated in both omnidirectional and cardioid patterns simply by switching up your preset configurations on the cabinet’s rear-panel LCD.

Scale up your system

The SRX900 series is an all-encompassing system, including loudspeakers, subwoofers, software, and a wealth of accessories that will take your sound to the next level. However, if you’re looking to start small and build your way up to a world-class system, the SRX900 series is built with effortless scalability in mind; every product in the SRX900 series is designed with the same voicing targets and phase characteristics of JBL’s other tour sound offerings to perfectly mix and match a system to your particular needs. Plus, SRX900-series subwoofers feature both 60Hz and 80Hz operating modes for compatibility with any and all SRX900-series full-range speakers.

Optimize your sound

No power amp, no problem! The SRX900 series’ fully integrated class-D power is an uncompromising design that’s tailor-made to get the most out of your speakers. In addition, powerful DSP features including Array Size Compensation, FIR-based Throw Distance Correction filters, 2,000ms of delay, and 24 user-adjustable filters are included to perfectly optimize your system, regardless of your setup and space. Finally, adjusting your controls is a breeze thanks to the SRX900 series combo of a rear panel LCD and WiFi control through JBL’s software suite!
