The PRX412M-WH is a premium,
utility/monitor speaker. The

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.
This version is designed for use
as a floor monitor or for overhead
suspension in a permanent
installation application where white
enclosures are desirable.
A passive network provides
accurate reproduction throughout
the crossover region.
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.
