SRX928S | DUAL 18IN POWERED SUBWOOFER, 1100W CONT, OMNIDIRECTIONAL OR CARDIOID

JBL SRX928S is a dual 18-inch powered subwoofer designed to provide high-output low-frequency reinforcement for JBL SRX900 professional sound systems. Built-in Class-D amplification and DSP make it a strong system-building choice for rental, touring, live production and fixed-install applications where substantial bass output is required without a separate amplifier rack.

The SRX928S uses two JBL 18-inch Differential Drive woofers and extends down to 31 Hz, delivering the low-frequency impact required for live music, DJs, entertainment venues and larger sound reinforcement systems. Selectable omnidirectional or cardioid operating configurations help integrators and production companies manage low-frequency coverage based on the deployment.

Dual Ethernet connections, HARMAN HControl support, onboard DSP and JBL Performance software integration allow the SRX928S to operate as part of a coordinated SRX900 system alongside powered line-array elements and other SRX900 components.

Note: The SRX928S is the large dual-18 ground-oriented powered subwoofer in the SRX900 family, while JBL's SRX915SF and SRX918SF provide flyable subwoofer options for array configurations.
