Application:
PRX612M is the most compact and
versatile speaker in the PRX600 Series. It
has been designed to deliver maximum
performance for its weight and size as both
a stage monitor and a front-of-house main
PA. Two user selectable EQ settings are
provided to optimize the system for either
application. With a dual socket pole mount,
the PRX612M is a perfect match with a
PRX618S subwoofer, offering a high
performance self-powered sub/sat system.
The PRX615M is comprised of a 305 mm
(12 in) 262F-1 Differential Drive®woofer, a
2408H-1, 37.5 mm (1.5 in) annular polymer
diaphragm, neodymium compression driver
mounted to a 90° by 50° horn, all driven by
1000 watt (dual 500 watt) Crown®Class-D
digital power amplifier. A proprietary DSP
chip is at the core of a fully featured input
section, providing user selectable system
EQ, protection, input sensitivity selection,
cross-over functionality, dynamic limiting
and discrete component optimization.
The amplifier input panel offers XLR or
¼in jack compatibility and a sensitivity
switch provides extra flexibility, making it
possible to connect literally any sound
source without using a mixer. Signal present
and limiter lights indicate the system status
and assist in setting the optimum level, via
the level control knob.
All PRX600 cabinets are built from a
combination of 25 mm (on the top and
bottom for added rigidity) and 18 mm,
strong, lightweight poplar plywood made
structurally sound with tongue and groove
joints. All PRX600 Series cabinets are
protected by JBL’s tour proven DuraFlex™
finish. Grilles are made from dent-resistant
16 gauge steel and handles are made from
lightweight, glass-filled nylon for added
strength and durability. All M10 suspension
points are constructed from 14 gauge steel
and have been tested with a yield-strength
of 1000 lbs. each.

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.
