About: JBL PRX715 15inch Powered Speaker

The 2-way 15" is the most recognizable form of portable PA loudspeakers and offers the perfect balance between size and performance. The PRX715 truly is an exception; it’s small, light weight, versatile and powerful.

The 2-way 15" offers the perfect balance between size and performance. The PRX715 truly is an exception; it’s small, light weight, versatile and powerful. The performance and asymmetrical design make this a perfect choice for musicians, entertainers and DJ’s when portability is key, or when hung by the suspension points, an exceptional light-duty installation speaker. All PRX700 Series speakers were designed to excel in sound reinforcement where challenging audio environments and loud volumes are the norm. For applications requiring full bandwidth sound reproduction, the PRX715 delivers the optimum balance. For live music, recorded music playback and speech the user has the option of tailoring the EQ. A microphone can be directly connected to the speaker input for quick PA applications. Coupled with a PRX700 sub-woofer the system becomes an efficient, full-range sound system.

The PRX715 is comprised of 15" 275G Differential Drive® woofer, a 2408H-2 37.5 mm (1.5 in) annular polymer diaphragm, neodymium compression driver mounted to a 90° by 50° horn, all driven by 1500 watt Class-D power amplifier. Sophisticated DSP 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.

All PRX700 cabinets are 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. All PRX700 Series cabinets are 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 overload lights indicate the system status and assist in setting the optimum level via the level control knob.
