Harman JBL Professional today introduced the PRX700 Series portable loudspeakers. The next generation in JBL’s PRX portable PA line, the PRX700 Series offers improvements in power, SPL and connectivity over the previous models. The PRX700 Series comprises seven new units: the PRX710, 10-inch, 2-way multipurpose loudspeaker; the PRX712, 12-inch two-way multipurpose loudspeaker and floor monitor; the PRX715, 15-inch, two-way full-range main system/floor monitor; the PRX725, 15-inch, two-way bass reflex loudspeaker; the PRX735, 15-inch, three-way full-range main system; the PRX715XLF, 15-inch, self-powered bass reflex subwoofer system; and the PRX718XLF, 18-inch self-powered bass reflex subwoofer system.
All PRX700 Series loudspeakers are powered with 1500W Class-D amplification. The PRX700 Series models feature new Differential Drive woofers that provide better heat dissipation, lower power compression and higher dynamic range versus conventional single-coil designs, resulting in better sound quality. In addition, the PRX700 woofers use magnetically saturated pole-pieces and an aluminum shorting ring, which significantly reduces nonlinear distortion.
The PRX700 Series features JBL’s patented waveguide technology, providing coverage throughout the system’s bandwidth. All models offer coverage of 90 degrees horizontal by 50 degrees vertical, which the exception of the PRX710, which features coverage of 100 degrees horizontal by 60 degrees vertical.
All PRX700 cabinets are built from a combination of 25mm (on the top and bottom for added rigidity) and 18 mm poplar plywood made structurally sound with tongue and groove joints. The cabinets also feature JBL’s DuraFlex finish, a dent-resistant 16-gauge steel grill, and lightweight glass-filled nylon handles for strength and durability. In addition, rigging points, pole sockets and vulcanized feet promote easy setup and luggability.
