The PRX412M is a premium,
utility/monitor speaker. The PRX412M
uses a 305 mm (12 in) woofer and a
2414H-C 25 mm (1 in) polymer
diaphragm compression driver for
300 watts (continuous) power capacity.
A 90° x 50° horn provides smooth,
even coverage whether used in the
vertical (mains) or horizontal (monitor)
orientation.
NL-2 and ¼" phone combination
connectors are provided. A passive
network provides accurate reproduction
throughout the cross-over region.
For use on a tripod or over a
subwoofer, JBL’s dual angle pole mount
is included. This feature allows the
speaker to be mounted in a vertical
position or with a 10° down tilt for
optimum audience coverage.
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.

JBL continually engages in research related to product improvement. Some materials, production methods and design
refinements are introduced into existing products without notice as a routine expression of that philosophy. For this
reason, any current JBL product may differ in some respect from its published description, but will always equal or
exceed the original design specifications unless otherwise stated.
