JBL SRX828SP 18" Dual Self-Powered Subwoofer System

The SRX828SP delivers authoritative low-end control with ergonomically designed handles that make repeated setup and repositioning straightforward and fatigue-free. Dual 2279F drivers with 3" voice coils and lower mass ferrite magnets ensure reduced weight without compromising power handling, distortion performance, or extended frequency response. This is a workhorse subwoofer engineered for touring rigs, rental inventories, and permanent installations where reliability and sonic precision matter.

Amplification & Power Performance

Crown DriveCore amplification supplies a commanding 2000W peak power rating (1000W per channel), with 1500W continuous output (750W per channel)—the highest power rating in its class. The 103dB signal-to-noise ratio delivers 141dB maximum SPL with exceptional headroom and minimal distortion across the entire operating bandwidth.

DSP Control & System Integration

A 400MHz Sharc DSP engine provides 20 parametric EQs, 2 seconds of delay, signal generators, input mixing, and amplifier monitoring alongside 50 user presets for rapid deployment across different venues. Full HiQnet network integration via Ethercon connectivity simplifies multi-unit configuration and remote control through Audio Architect, HiQnet Motion Control iOS app, and standalone Android/iOS applications.
