JBL SRX915SF 15-inch Subwoofer
The SRX915SF is a powered subwoofer engineered for serious live sound and installed applications where low-end authority and precision control are non-negotiable. Its compact footprint and flying-ready design make it manageable on site while delivering the punch and articulation expected from JBL's touring-grade lineup. The integrated Class D amplifier and extensive DSP toolset allow real-time optimization across different venues and configurations.
Amplification & Power Handling
A built-in 2,500-watt Class D amplifier with 1100 watts continuous power rating drives the JBL 2276H 15-inch woofer with precision and efficiency. The dual 3-inch voice coil design and Differential Drive technology ensure tight, controlled response across demanding applications without thermal stress.
Frequency Response & Audio Performance
The SRX915SF delivers a linear low end down to 36Hz with 130dB maximum SPL, operating across a 43–80 Hz frequency response optimized for subwoofer duty in full-range systems. Advanced DSP features—including LevelMax limiting, 24 user-adjustable filters, 2,000ms delay, Array Size Compensation, and FIR-based Throw Distance Correction—enable precise tuning to room acoustics and system topology.

Frequently Asked Questions
What makes the SRX915SF different from a standard studio subwoofer?
The SRX915SF is optimized for live and installed sound with a 43–80 Hz operating range, 2,500-watt amp, and 130dB SPL capability—far higher output and tour-focused design than typical studio subs. Its extensive DSP toolkit (24 filters, Array Size Compensation, FIR Throw Distance Correction) is built for real-time venue adaptation rather than home studio use.
Can I control and adjust the sub remotely or over a network?
Yes. The SRX915SF includes dual Neutrik etherCON Ethernet ports for networked DSP control via HControl protocol and JBL Performance software, plus a rear-panel LCD for direct adjustment. This makes it ideal for touring and multi-subwoofer arrays where remote tuning saves time on site.
What's the frequency response, and will it work with full-range speakers?
The SRX915SF operates 43–80 Hz with linear extension to 36Hz, making it a pure subwoofer designed to blend seamlessly under full-range PA and monitor systems. It's not intended as a standalone bass unit; pair it with main speakers to cover the midrange and treble.
Is it suitable for permanent installation or touring?
Both. The sub features reinforced 18mm birch plywood construction, integrated 3-point flying mount hardware, and universal power supply, so it's equally at home in a touring rig or a permanent venue install.
What's included, and do I need external processing?
The SRX915SF includes the sub, Class D amp, built-in DSP, XLR input, and Ethernet ports for control. No external processor is required; all filtering, limiting, and delay functions are onboard.
