The MRX525 is an excellent choice when the application calls for high performance and simplicity. A pair of MRX525s and a single, high-power amplifier is a complete sound system capable of reinforcing bass and kick drum or playing high-level music in clubs and other venues. The MRX525 is comprised of two 380 mm (15 in) 265H Differential Drive® woofers with combined power handling of 800 watts (continuous). For the high frequencies, 2408H 37.5 mm (1.5 in) annular polymer diaphragm, neodymium compression driver is mounted to a 70° x 70° horn.

The 70° coverage angle of the MRX525 is wide enough to provide coverage of an audience when used one-per-side yet narrow enough to allow splaying of multiple enclosures without excessive coverage overlap. The enclosure is constructed of quality plywood and coated in JBL's rugged DuraFlexT finish. The attractive CNC-machined, 16-gauge steel grille wraps around the sides of the enclosure. The grilles are internally lined with an acoustically transparent screen to provide additional driver protection and give a very professional appearance.
