JBL SRX915M Description

The JBL SRX915M is engineered for sound professionals who need powerful full-range performance from a multi-purpose loudspeaker. Its JBL 275F 15-inch woofer incorporates patented Differential Drive technology with dual 2-inch voice coils and a ferrite magnet. A JBL 2408H-1 neodymium compression driver handles high-frequency reproduction, providing detailed vocal clarity and controlled projection.

The integrated Class-D amplifier delivers 600W continuous power, divided into 400W for the low-frequency section and 200W for the high-frequency section. With a maximum SPL of 134dB and a frequency range of 50Hz–20kHz, the SRX915M is suitable for live music, DJ systems, vocal reinforcement, stage monitoring, and other demanding sound applications.

JBL's rotatable Progressive Transition waveguide provides a 90° horizontal by 60° vertical coverage pattern in its standard orientation. The speaker's voicing and phase response are optimized to complement SRX900 line-source products, while an available 80Hz high-pass preset supports configurations using SRX900 subwoofers.

Integrated digital signal processing provides comprehensive loudspeaker management without requiring an external processor. The rear-panel LCD supports direct configuration, while 24 user-adjustable filters, up to 2,000ms delay, and additional processing tools allow the speaker to be adapted to different environments. JBL's software suite supports system control and monitoring on Windows, macOS, and iPadOS devices.

The multi-purpose enclosure is constructed from exterior-grade Baltic birch plywood with a durable DuraFlex finish. Its low-profile design incorporates a 45° monitor angle for floor wedge applications, two integrated carrying handles, and seven M10 QuickLink suspension points for use with compatible rigging hardware and accessories.
