JBL PRX725 1500W Dual 15" Two-Way Full-Range Self-Powered Speaker System, 20K Ohms Balanced/10K Ohms Unbalanced, 49Hz-17kHz Normal Frequency Response

The JBL PRX725 1500W Dual 15" Two-Way Self-Powered Speaker System is designed for live sound reinforcement applications, such as concerts, schools and houses of worship, among others. The speaker is built from poplar plywood with an obsidian DuraFlex finish using tongue and groove joinery for stronger bracing and less box vibration. It utilizes two 15" low-distortion, low-frequency woofers, a wave-guided 1.5" diameter neodymium compression driver and a class-D amplifier to achieve a maximum SPL of 139 dB and a frequency response of 40 to 18,500 Hz.

For easy transport and setup, the speaker includes an injection molded handle, 16-guage steel dent-resistant cloth-backed grills, integrated M10 suspension points for hanging and an integrated M10 pull back point for positioning.

The back panel of the speaker features two combination 3-pin XLR and 1/4" balanced inputs for microphone and line with a selector switch as well as a pair of unbalanced RCA inputs. Two gain control knobs allow you to adjust the input signal on channels 1 and 2 and a 3-pin XLR male thru connection with thru selector switch enables passing audio to another powered speaker or amplifier. The device includes an EQ boost button for widening the speaker's frequency response and a button for turning on and off the power/standby LED on the front of the device.

The speaker's crossover, dynamic limiting, component optimization and selectable EQ boost is handled by a dbx type IV circuit. The unit can be used by itself or connected with other speakers and subwoofers to build larger systems for increased crowd coverage and low frequency response.
