Purpose-built for modern SRX900 systems, the JBL SRX915M is a two-way, 15" powered point-source loudspeaker designed to deliver extended low-frequency output and increased headroom in demanding professional environments. By combining JBL’s Differential Drive 15" low-frequency transducer, a 1.5" annular-diaphragm compression driver and a rotatable 90° × 60° Progressive Transition waveguide, it produces powerful controlled output with smooth predictable coverage. Integrated Class-D amplification, advanced DSP with user-adjustable filters and delay, global power compatibility and networked control via Harman HControl make the SRX915M a robust plug-and-play solution for main PA and high-performance stage monitor roles within modern SRX900 systems.
Advanced Acoustic Design With 15" Low-Frequency Impact
At the heart of the SRX915M is a purpose-built two-way acoustic system optimized for power and control. A JBL 275F 15" woofer using patented Differential Drive technology delivers extended low-frequency response down to 50Hz while maintaining excellent thermal efficiency and reduced weight. High frequencies are handled by a neodymium 1.5" annular-diaphragm compression driver coupled to a 90° × 60° rotatable Progressive Transition waveguide, providing smooth predictable coverage and strong gain before feedback. System voicing and phase response are carefully optimized to integrate seamlessly with SRX900 line-source products.
High Output With Controlled Coverage
Tailor-made for demanding live sound applications, the SRX915M delivers up to 134dB peak SPL with clarity and consistency. Its optimized acoustic architecture provides strong projection and controlled dispersion, making it well suited for front-of-house reinforcement, side-fill duties or monitor applications. An 80Hz high-pass preset is available when pairing with SRX900 subwoofers, allowing the system to scale easily into larger full-range deployments.
Integrated Class-D Amplification and Professional DSP
The SRX915M is fully self-powered and features onboard Class-D amplification delivering up to 880W peak power with optimized thermal management. Integrated DSP provides 24 user-adjustable filters, up to 2,000 ms of delay and essential loudspeaker management tools for precise system tuning. A rear-panel LCD with encoder control allows fast configuration on site, while optimized latency supports reliable performance for both main PA and monitor use.
Purpose-Built for Main PA and Stage Monitor Use
The enclosure design of the SRX915M supports multiple deployment scenarios without compromise. When used as a stage monitor, its low-profile cabinet provides a precise 45º monitor angle for accurate performer coverage. For main PA or fill applications, the rotatable waveguide and controlled dispersion support flexible positioning across a wide range of venues. Seven M10 QuickLink suspension points, dedicated U-brackets, truss-mount options and pole-mount compatibility ensure fast secure integration into portable and installed systems.
Tour-Ready Construction and SRX900 System Integration
Constructed from outdoor-grade Baltic birch plywood and finished with JBL’s rugged DuraFlex coating, the SRX915M is built to withstand the rigors of professional touring and installation while maintaining a clean modern appearance. Network control via dual etherCON ports enables monitoring and configuration across Windows, macOS and iPadOS platforms. As part of the SRX900 ecosystem of loudspeakers, subwoofers, accessories and software, the SRX915M delivers scalable reliable performance for professionals who demand power flexibility and confidence from their sound system.
