Application:
< The PRX815XLF extended low frequency
subwoofer was designed and engineered to
provide sub bass frequencies with accuracy and
power. Used as a single sub in a sub/ sat system
or in multiples as part of a scalable, large format
sound reinforcement system, the PRX815XLF
performs with exceptional efciency and
control. The subs are stackable and light-weight,
ensuring quick set-ups and tear-downs. Due
to their rugged construction, they are perfect
for AV rental inventories. With the integrated
stereo pass-thru this is the most powerful low-
frequency complement to the PRX full-range
systems. The addition of a polarity reverse option
further enables system optimization. PRX800
subwoofers feature a standard M20 threaded pole
cup that can accept most modern subwoofer-
mounted speaker poles
< The PRX815XLF is a high performance self-
powered subwoofer system with remote Wi-Fi
control of onboard DSP EQ parameters. The
PRX815XLF is comprised of a powerful 2275H
Differential Drive
®
dual voice-coil and magnetic
gap, woofer driven by a 1500 Watt Class-D
power amplier. Sophisticated DSP is at the
core of a fully featured input section, providing
user selectable cross-over functionality, polarity
optimization, protection, dynamic limiting and
discrete component optimization.
< All PRX800 cabinets are built from 18 mm,
strong, light-weight poplar plywood made
structurally sound with tongue and groove
joints. All PRX800 Series cabinets are protected
by JBL’s tour proven DuraFlex™ nish. Grilles
are made from dent-resistant 16 gauge steel and
handles are made from light-weight glass-lled
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.
< The amplier input panel offers stereo inputs
with XLR or ¼ inch jack compatibility. A
user selectable crossover ensures a smooth
transition to full-range system connected to the
stereo outputs. Signal present and limiter lights
indicate the system status and assist in setting
the optimum level via the level control knob.
