About: JBL PRX735 15inch Three-Way Full-Range Powered Speaker

The PRX735 is a self-powered, lightweight three-way loudspeaker system capable of delivering a very high level of performance over a broad bandwidth.

This speaker is ideally suited to applications where the program material exhibits subtlety and nuance. Perfectly capable of reproducing high fidelity full range sound without a subwoofer, when coupled with the extended low frequencies of the PRX718XLF, complete control over the entire audio spectrum is attained. As with all the full-range PRX700 Series systems, two EQ selections can be used to optimize the system for the program material and/or environment. The input section also accommodates either Line or Mic/Instrument level inputs.

The PRX735 is a self-powered, lightweight three-way loudspeaker system capable of delivering a very high level of performance over a wide bandwidth. The PRX735 is comprised of one 15 in 275G Differential Drive® woofer, a 165 mm (6.5 in) 196H horn-loaded mid-range and 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 a 1500 watt Audio 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.
