102 mm (4 in) voice-coil
neodymium compression driver for
high-power capacity and very lightweight
75° x 50° coverage
Bi-amplified or full-range passive
operation
On SRX725F model, five suspension
points may be used with optional
M10 eyebolts or detachable track
fittings
Applications
Live sound reinforcement for vocals
and musical instruments
High-level music playback
The SRX725 is an excellent choice
when the application calls for high
performance and simplicity. A pair of
SRX725s 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 SRX725 is
comprised of two 380 mm (15 in)
2265H patented* Differential Drive
woofers with combined power
handling of 1200 watts (continuous).
For the high frequencies, the
legendary 2452H 102 mm (4 in) voicecoil, neodymium compression driver is
mounted to a 75° by 50° aluminum
horn. The 75° coverage angle of the
SRX725 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.
Bi-amp or full-range passive
operation may be selected by means
of a recessed, high-current switch
mounted on the input plate.
For applications requiring
suspension, a flying version, the
SRX725F is available. The F version
offers the option of selecting
economical, forged eyebolts (not
included) for fixed installation or the
convenience of detachable track
fittings (not included) for portable
applications.
*U.S. Patent 5,748,760; other U.S. and foreign patents
pending.

The enclosure is constructed of top quality birch plywood and coated in
JBL’s rugged DuraFlex™ finish. The attractive CNC-machined, 16-gauge steel
grille wraps around the sides of the enclosure so there are no protruding lips
on the front of the box to create acoustical interference. The grilles are
internally lined with acoustically transparent foam to provide additional driver
protection and give a very professional appearance.
