12" 2-Way Active Speaker, 1500W, Remote Control


A full-range speaker designed for main system and floor monitor applications, the JBL PRX812W features a 12", 2-way, bass-reflex design, powered by a 1500-watt class-D amplifier. It delivers an incredible amount of volume in a lightweight, compact form factor.

The PRX812W is a compact and versatile speaker in the PRX800 Series that offers remote Wi-Fi® control of onboard DSP EQ parameters. It's been engineered to deliver maximum performance for its size and weight, as both a front of house main PA and/or a stage monitor. Two user-selectable EQ settings provide optimization of the system for either application. With its dual socket pole mount, the PRX812W is a perfect match with a PRX818XLFW subwoofer (sold separately), offering a self-powered, high performance sub/sat system. It consists of a 12" Differential Drive® woofer, a 2408H-1, 1.5" (37.5mm) annular polymer diaphragm, a neodymium compression driver mounted to a 90° by 50° horn, and all driven by 1500 watt Class-D digital power amplifier. Sophisticated DSP is at the core of a fully featured input section as well, providing user-selectable system EQ, input sensitivity selection, protection, dynamic limiting, cross-over functionality, and discrete component optimization.
