The JBL PRX615M 15" two-way Self-Powered Bass-Reflex Loudspeaker is the most recognizable form of portable PA loudspeaker and offers the perfect balance between size and performance. The PRX615M truly is an exception; it is small, light weight, versatile and powerful. The performance and asymmetrical design make this a perfect choice for musicians, entertainers and DJs when portability is key or when hung by the suspension points, an exceptional light-duty installation speaker. The JBL PRX615M speaker is designed to excel in the real world of sound reinforcement where challenging audio environments, high ambient noise levels and loud volumes are the norm. For applications requiring full bandwidth sound reproduction, using only a pair of speakers, the PRX615M delivers the optimum balance. For live music, recorded music playback and speech, the user has the option of tailoring the EQ, 'flat' for speech intelligibility and 'boost' for enhanced bass and crisp highs in recorded music playback. A microphone can be directly connected to the speaker input for quick on-the-fly PA applications. Coupled with a PRX600 sub-woofer, the system becomes an incredibly efficient, loud, full-range sound system.
The PRX615M is comprised of a 380 mm (15 in) 265F-1 Differential Drive dual voice-coil and magnetic gap, neodymium woofer, a 2408H-1 37.5 mm (1.5 in) annular polymer diaphragm, neodymium compression driver mounted to a 90deg. x 50deg. horn, all driven by 1000 watt (dual 500 watt) 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" 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 PRX615M 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. JBL PRX615M 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.
