Description
JBL SRX828SP 18" Dual Self-Powered Subwoofer System
The SRX828SP brings studio-grade low-end precision and power to tracking sessions, mixing suites, and mastering facilities requiring accurate sub-bass monitoring and control. 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. Built for critical listening environments where bass reproduction directly impacts mix decisions and final audio quality.
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, ensuring clean, uncolored low-frequency reproduction during extended mixing and mastering sessions.
DSP Control & Studio 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 reconfiguration across different room treatments and tracking scenarios. Full HiQnet network integration via Ethercon connectivity streamlines multi-unit setup and remote tuning through Audio Architect, HiQnet Motion Control iOS app, and standalone Android/iOS applications, enabling precise acoustic optimization without interrupting workflow.
