<div>
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.

<h3>High-performance dual 18-inch drivers</h3>
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.
