JBL Professional SRX915SF - 15" Powered Flyable Subwoofer with DSP and Networking (etherCON)

JBL Professional SRX915SF - 15" Powered Flyable Subwoofer with DSP and Networking (etherCON)

The JBL SRX915SF is a 15" flyable active subwoofer optimized for suspended array deployment or ground-stacked with SRX900 Series full-range systems. It features passively cooled Class D amplification with user DSP and full control via JBL Performance HControl software. Its JBL 2276H Differential Drive® transducer (dual 3" voice coils, double air gap) delivers low-distortion, high-dynamics bass with a frequency range (-10 dB) 36–100 Hz , response (-3 dB) 43–80 Hz , and a maximum SPL of 130 dB peak . The large LF port design reduces high-level turbulence, and the 18 mm birch enclosure ensures road durability. It features three-point rigging , an M20 pole socket , and dual Ethernet ports with Neutrik etherCON connectors for monitoring and networking.

Main features

• High-performance, high-density solution: truck-pack format for efficient transport and rapid deployment.
• High-power transducer: 15" JBL 2276H ( Differential Drive® ) for low distortion and wide dynamic range.
• Integrated amplification: Class D with 1,100 W continuous / 2,500 W peak ; convection cooling with external heatsink and internal fan on demand.
• DSP and Control: 24 user filters, delay up to 2,000 ms , Array Size Compensation and FIR-based Throw Distance Correction ; 60/80 Hz presets and omni/cardioid modes selectable from the rear LCD or via network.
• Intelligent Protection: LevelMax with advanced excursion control algorithms to protect the transducer.
• Full connectivity: balanced audio on 2 × XLR (IN/OUT) , 2 × etherCON 100 Mb/s network, powerCON TRUE1 IN/OUT with universal 100–240 VAC power supply.
• Touring construction: Exterior birch plywood with DuraFlex™ finish, steel grille, and IP54 environmental rating ( rain cover recommended for use in direct rain).
• System integration: Same width and hardware as SRX906LA for mixed arrays; compatible with SRX906LA AF frame, ACK1, transporters, and sleeves.

Product benefits

• Ready-to-use system: integrated amplification and DSP ensure consistent performance in any environment.
• Clean, controlled bass: Oversized port and LevelMax limiting to maintain linearity at high SPLs.
• Simple network management: setup, monitoring and cardioid presets from JBL Performance via HControl.
• Versatility in assembly: flown individually or combined with SRX906LA, stacked on the ground or on an M20 post.

Use cases

• Tours and rentals that require high-density and rapid deployment.
• Indoor/outdoor events requiring low frequency coverage control (omni/cardioid).
• Temporary installations and venues with floor space restrictions, using suspended arrays.

Compatibility and mounting

• Rigging: Integrated three-point system with captive plates and quick-release pins.
• Mixed arrays: direct combination with SRX906LA in cantilever or stacked configuration thanks to the same width and hardware.
• Operating modes: omnidirectional or cardioid by selecting preset and orientation of the units.
