JBL Professional SRX818SP 18" Portable Self-Powered Subwoofer System, Black

Deliver authoritative, low-frequency impact where it matters most. The JBL Professional SRX818SP 18-inch self-powered subwoofer puts tight, room-filling bass at the heart of your rig with pro-grade reliability and flexible control. Built around a robust 18-inch JBL transducer and DriveCore amplification by Crown, the SRX818SP provides 750W RMS of dependable power and a usable response down to 35Hz (up to 120Hz), so kick drums and low-frequency effects remain punchy without distortion. Premium, user-configurable DSP and HiQnet network control let you tune presets, apply V5 touring system tunings, and monitor performance remotely—ideal for touring stages, fixed installations, or AV monitoring and security control rooms where precise monitoring and system oversight are essential. The rugged, portable cabinet accepts pole mounts and caster kits for fast deployment, while JBL-engineered presets speed setup in complex systems. If you need deep, controllable bass for live sound, corporate AV, or surveillance/monitoring environments, the SRX818SP is a no-compromise pro subwoofer.
