JBL PRX412M 12" Two-Way Stage Monitor and Loudspeaker System

The PRX412M is a compact, lightweight workhorse designed to deliver consistent output across live performance, stage monitoring, and speech reinforcement applications. At 35 lbs with a footprint of 22.6" x 13.9" x 15.7", it balances portability with serious acoustic capability, making it equally at home on a tripod or suspended from rigging points.

Audio Performance & Coverage

This two-way system pairs a 12" woofer with a 1" polymer diaphragm compression driver to achieve a 95 dB SPL sensitivity (1W@1m) and a rated maximum output of 126 dB SPL peak. The 90° x 50° coverage pattern ensures even, smooth response both on and off axis, while the frequency response of 62Hz–19kHz (±3dB) and full range down to 50Hz (–10dB) handles everything from kick drum to vocals without gap or coloration.

Design & Build Quality

The PRX412M employs a birch/poplar multi-laminate hardwood enclosure finished in tough DuraFlex™ for road durability. A 16-gauge protective steel grille backed with acoustically transparent cloth guards the drivers, while SonicGuard™ high-frequency driver protection prevents damage from excessive power handling without interrupting performance. Dual-angle pole sockets and twelve M10 suspension points constructed from 14-gauge steel provide flexible mounting options for both temporary and light-duty permanent installations.
