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.
