JBL SRX918SF 18" Powered Flyable Subwoofer – High-Performance ...
The JBL SRX918SF 18" Powered Flyable Subwoofer is designed to deliver powerful, precise, and reliable low-frequency reinforcement for professional audio applications. As part of the SRX900 Series, this subwoofer is ideal for rental companies, touring artists, DJs, and fixed installations that demand high-density performance in a truck-pack-friendly format.
Equipped with an 18" Differential Drive® woofer and powered by a passively cooled Class-D amplifier, the SRX918SF produces an impressive peak SPL of 134 dB with transparent, linear bass response down to 35 Hz. The large low-frequency port design reduces turbulence and improves airflow, ensuring clean performance even at maximum output.
This subwoofer features user-controllable DSP with 24 adjustable filters, up to 2000 ms of delay, FIR-based throw-distance correction, and array size compensation. The rear-panel LCD provides direct access to presets and settings, while dual Neutrik etherCON ports support HARMAN’s HControl Ethernet protocol for remote system control via JBL Performance software on Windows, macOS, and iPadOS.
Built for real-world use, the SRX918SF is housed in a reinforced 0.7" plywood enclosure with an integrated three-point rigging system, making it suitable for both flown and ground-stacked configurations. An M20 threaded pole mount enables compatibility with full-range speakers. Designed to scale with any SRX900 system, it offers seamless integration with JBL’s professional touring products, ensuring consistent voicing and phase coherence across large systems.
