Featuring 3 inch voice coils, 1000 Watts of Crown Amplification, rugged enclosures with JBL’s patented DuraFlex coating, and a full suite of onboard user configurable DSP, the SRX818SP is a perfect all in one solution wherever high performance, comprehensive control, and pristine sound are required.

For incredible extended low frequency response, the SRX818SP uses an 18-inch woofer with JBL’s patented Differential Drive Technology for reduced weight while maximizing power amp efficiency. 3” voice coils and dual ferrite drivers deliver exceptionally low distortion and extended low frequency response.

The extraordinary amount of power and the rugged design of the new SRX800 line are enough to make it the best portable loudspeaker system on the market, but users will also enjoy an unprecedented level of control and configurability with the system. The SRX818SP features a full suite of onboard user configurable DSP including 20 PEQ’s, 2 seconds of delay, signal generators, input mixing, amplifier monitoring, and 50 slots for recallable presets, including 10 JBL-engineered application presets.

In addition, the system is compatible with V5 JBL Tunings, and features 96kHz FIR Filters, and LevelMax Limiting providing compatibility with the flagship Vertec and VTX touring systems. And with M10 suspension points and indexed feet, the SRX818SP can be configured for a variety of applications, including being stacked in a cardioid configuration for large shows on stage.

All of this is easily controlled by Audio Architect, HiQnet Motion Control iOS app, and a standalone application for iOS, Android, Mac, and PC. Simple wired control is provided via an Ethercon connector on the back of the system and wireless control is possible using a standard off the shelf wireless router.
