The JBL PRX625 is a self-powered, lightweight two way loudspeaker system capable of delivering a very high level of performance over a broad bandwidth. The PRX625 is comprised of two 380 mm (15 in) 265F-1 Differential Drive woofers, 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 a multi-channel Crown Class-D power amplifier. A proprietary 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 amplifier input panel offers XLR or ¼ in 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 overload lights indicate the system status and assist in setting the optimum level, via the level control knob.
The JBL PRX625 cabinet is built from a combination of 25 mm (on the top and bottom for added rigidity) and 18 mm, strong, lightweight poplar plywood made structurally sound with tongue and groove joints. The JBL PRX625 cabinet is protected by JBL's tour proven DuraFlex finish. Grilles are made from dent-resistant 16-gauge steel and handles are made from lightweight, 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.
