The JBL SRX915SF is a high-output, active 15-inch subwoofer engineered to integrate seamlessly with the SRX900 series. Designed for flown or ground-stacked use, it delivers deep, articulate bass with intelligent DSP control, rugged construction, and universal power compatibility—making it ideal for touring, installations, and rental systems.
The SRX915SF is a flyable powered subwoofer designed to support SRX900 full-range systems, including SRX906LA arrays. Its compact form factor, paired with JBL’s high-output 2276H transducer, delivers premium low-frequency performance in mobile or installed sound environments.
This subwoofer features built-in DSP and a passively cooled Class D amplifier for reliable operation with minimal setup. The universal power supply allows deployment worldwide. JBL’s LevelMax limiting protects components using intelligent excursion control, while user-defined DSP parameters enable custom configurations for cardioid or omni use.
Setup and management are intuitive through a rear-panel LCD and JBL Performance software, accessible via dual Neutrik etherCON Ethernet ports using HARMAN’s HControl protocol. The rugged cabinet is built from 18 mm birch plywood with a large low-frequency port and M20 mount. A three-point rigging system ensures versatile suspended or ground-stacked installation.
