Application:
The 2-way 15"; the most recognizable form
of portable PA loudspeakers, the perfect
balance between size and performance. The
PRX515 truly is an exception; it’s smaller and
lighter without compromising on
performance. For applications requiring full
bandwidth sound reproduction, using only a
pair of speakers, the PRX515 delivers the
optimum balance. For live music, recorded
music playback and speech the user has the
option of tailoring the EQ, ‘flat’ for speech
intelligibility, and ‘boost’ for enhanced bass
and crisp highs in recorded music playback.
A microphone can be directly connected to
the speaker input for quick on-the-fly PA
applications.
The PRX515 is a self-powered, lightweight
two-way loudspeaker system capable of
delivering a very high level of performance.
The PRX515 is comprised of a 380 mm (15
in) 265F Differential Drive®woofer, a 2408H
37.5 mm (1.5 in) annular polymer diaphragm,
neodymium compression driver mounted to a
70° by 70° horn, all driven by a multi-channel
Crown International Class-D digital power
amplifier. A propriety 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 enclosure is constructed of quality
plywood and coated in JBL’s rugged
DuraFlex™ finish. Durable polypropylene
end-caps add extra protection for the cabinet.
An integrated pole mount on the bottom end-
cap enables easy deployment. The CNC-
machined 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 grille is also lined
with an acoustically transparent foam to
provide additional driver protection.
The amplifier input panel offers XLR or ¼
inch 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
overload lights indicate the system status and
assist in setting the optimum level, via the
level control knob.

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.
