Application:
< PRX812W is a compact and versatile speaker in the
PRX800 Series with remote Wi-Fi control of onboard
DSP EQ parameters. 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 PRX812W is a perfect match
with a PRX818XLFW subwoofer, offering a high
performance self-powered sub/sat system.
< The PRX812W is comprised of a 12” 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 1500 watt
Class-D digital power amplier. Sophisticated DSP 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.
< All PRX800 cabinets are built from a combination
of 25 mm (on the top and bottom for added rigidity)
and 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 XLR or ¼ inch jack
compatibility and a sensitivity switch provides extra
exibility, 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.

JBL continually engages in research related to product improvement. Some materials, production methods and design renements 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 specications unless
otherwise stated.
