JBL SRX828SP Powered Subwoofer Speaker

When you really need to bring the bass, the JBL SRX828SP pumps 2,000 watts of boom through dual 18" woofers -- along with tone shaping through on-board DSP.

The SRX828SP represents the next generation of premium powered loudspeaker technology from JBL Professional. Featuring 3 inch voice coils, 2000 Watts of Crown Amplification, rugged enclosures with JBL's patented DuraFlex coating, and a full suite of onboard user configurable DSP, the SRX828SP is a perfect all in one solution wherever high performance, comprehensive control, and pristine sound are required.

With M10 suspension points and indexed feet, the SRX828SP can be configured for a variety of applications, including being stacked in a cardioid configuration for large shows on stage.

For incredible extended low frequency response, the SRX835P uses an 18-inch woofer with JBL's patented Differential Drive Technology for reduced weight while maximizing power amp efficiency. Its 3" voice coils and dual ferrite drivers deliver exceptionally low distortion and extended low frequency response.

Don't pay attention to the previous review. I had 4 EV ETX18SP subwoofers that destroy the QSC KW181s and sold those for the JBL. The EV were great but JBL did not hold back on these, I've been a fan of the SRX728S since they came out and so have many sound professionals. These new SRX do not disappoint! I currently have 4 of the SRX828SP and all I can say is WOW! The subs are massive but so is the sound, 141db each.
