PRX312MD is a 12-inch portable two-way speaker system designed for stage monitoring at live performance or speech.

For the low ends, PRX312MD uses a premium 12-inch low-frequency driver with an edge-wound ribbon voice coil of 2 ½ inch (64mm) in diameter to bring the system solid bass, high efficiency, and large power-handling capabilities.

A JBL 2412 1-inch ferro-fluid cooled compression driver with a titanium diaphragm provides the system with clean and warm high notes and uncompromised reliability.

JBL SonicGuard™ technology improves system stability by protecting the high-frequency driver from excessive power without interrupting the show.

Apart from the drivers, fault-free performance of the system also relies on the precision-crafted crossover network, which feeds the two drivers with clear-cut frequencies with minimum overlap and is capable of handling high power with its high-voltage capacitors and inductors.

The patented Progressive Transition™ waveguide mounts on top of the tweeter and provides the system with superior coverage control, reduced distortion, and smoother frequency response.

PRX312MD encloses all the acoustic components in a rugged cabinet constructed from 15mm MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency response.

Two all-steel handles are integrated into the sides of the case to make transport and setup easier. A 36-mm socket allows PRX312MD to be mounted on a speaker pole and to work as a main or fill. The socket supports either up-straight standing or 10° tilting, helpful when the audience coverage needs to be uniformed.

For the front of the speaker, a dent-resistant grille made from 18-gauge perforated steel protects the components inside from damage on the move or during the show.
