About This Product

JBL Pro PRX725 Dual 15” Two-Way Full-Range Main System Loudspeaker

The PRX700 Series represent an evolutionary step in the efficient use of amplifier power, rugged durability and enhanced versatility in a self-powered loudspeaker designed from the ground up to perform in the real world of sound reinforcement where challenging audio environments, high ambient noise levels and loud volumes are typical. They are the first systems to use our patented Differential Drive technology with ferrite drivers featuring high power, wide bandwidth and low distortion. Versatile, scalable, easy-to-transport and set up, the PRX700 Series use JBL's tour tested technology throughout for a lifetime of reliable performance you can trust.

The PRX725 is a self-powered, lightweight two-way loudspeaker system capable of delivering a very high level of performance over a broad bandwidth.

JBL Pro PRX725 Features:

  • 139 dB peak SPL.
  • Dual 15" Differential Drive low-frequency driver for low-distortion and higher SPL.
  • 1.5” diameter next generation JBL neodymium compression driver.
  • JBL designed waveguide for accurate coverage.
  • Efficient Class-D amplifier technology.
  • Normal and Boost user selectable EQ presets.
  • DSP input section, crossover, dynamic limiting, component optimization, selectable system EQ.
  • Line level and direct microphone input capability.
  • Professional XLR-1/4" combination inputs, RCA inputs, and XLR loop-through.
  • Multiple injection molded handles with backing cup for easy transport.
  • Integrated M10 suspension points for easy setup.
  • Lightweight poplar plywood cabinets made structurally sound with tongue and groove joints and protected by JBL’s tour proven DuraFlex finish.
  • Cloth backed, dent-resistant 16 gauge steel grilles.

JBL Pro PRX725 Application

If a simple set-up is required and full bandwidth output at high levels is a must, then the PRX725 is most likely the optimum solution. With the same foot print as the PRX715, the dual 15" woofer design creates enough low frequency content to serve most live music or music playback situations. When coupled with a PRX subwoofer (or multiple subwoofers) the system becomes a high volume sound reinforcement solution, perfect for regional tour companies and AV Rental companies looking for a scalable, easy to employ audio solution. We recommend using the PRX718XLF in conjunction with the PRX725 as the extended low frequency capabilities of the subwoofer compliment the frequency response of the PRX725.

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 on-the-fly PA applications.

The PRX725 is a self-powered, lightweight two-way loudspeaker system capable of delivering a very high level of performance over a wide bandwidth. The PRX725 is comprised of two 380 mm (15 in) 275 Differential Drive woofers, a 2408H-2, 37.5mm (1.5 in) annular polymer diaphragm, neodymium compression driver mounted to a 90° by 50° horn, all driven by a 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.
