The PRX425 is an excellent choice when the application calls for high performance and simplicity. A pair of PRX425s 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 PRX425 is comprised of two 380 mm (15 in) woofers with combined power handling of 600 watts (continuous). For the high frequencies, 2414H-C 25 mm (1 in) polymer diaphragm, compression driver is mounted to a 90° x 50° horn. The 90° coverage angle of the PRX425 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 birch/poplar multi-laminate hardwood and coated in JBL’s rugged DuraFlex™ ﬁnish. The distinctive 16-gauge steel grille is CNC-machined for precision. The grilles are internally lined with an acoustically transparent screen to provide additional driver protection and give a very professional appearance
