Review Summary
The JBL PRx612M is the most compact and versatile speaker in the PRx600 Series. Designed to deliver maximum performance for its size and weight, the PRx612M is ideal for use as a stage monitor or as a main PA for front-of-house applications. Two user selectable EQ settings are provided to optimize the system for either application. With a dual socket pole mount the PRx612M is a perfect match with a PRx618S subwoofer, offering a high performance self-powered sub/sat system.
The PRx612M is comprised of a 305 mm (12in) 262F-1 differential drive woofer, a 2408H-1, 37.5 mm (1.5 in) annular polymer diaphragm, neodymium compression driver mounted to a 90Deg. by 50Deg. horn, all driven by 1000 watt (dual 500 watt) Crown Class-D digital power amplifier. A propriety DSP chip is at the core of a fully featured input section, providing user selectable system EQ, protection, input sensitivity selection, cross-over functionality, dynamic limiting and discrete component optimization.
The PRx612M cabinet is built from a combination of 25mm (on the top and bottom for added rigidity) and 18mm, strong, light-weight poplar plywood made structurally sound with tongue and groove joints. This cabinet is protected by JBL's tour proven DuraFlex finish. Grilles are made from dent-resistant 16 gauge steel and handles are made from light-weight glass-filled nylon for added strength and durability. All M10 suspension points are constructed from 14 gauge steel and have been tested with a yield-strength of 1000 lbs. each.
The amplifier input panel offers XLR or ¼ inch jack compatibility and a sensitivity switch provides extra flexibility, making it possible to connect literally any sound source without using a mixer. Signal present and limiter lights indicate the system status and assist in setting the optimum level, via the level control knob.
