Applications
- 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 efficiency
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 PRX818XLF is a high
performance self-powered subwoofer system with remote Wi-Fi control of
onboard DSP EQ parameters. The PRX818XLF is comprised of a powerful 2278G
Differential Drive® dual voice-coil and magnetic gap, woofer driven by a
1500 Watt Class-D power amplifier. 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™ finish. Grilles are made from dent-resistant
16 gauge steel and handles are made from light-weight 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 - The amplifier 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.
