JBL JRX212 User Manual
Key Features:
䉴
JBL 12 in low frequency driver
with a 64 mm (2.5 in) diameter
edgewound voice coil which
provides more cross-sectional wire
area in the voice coil gap than
round wire designs, for greater
efficiency and power handling.
䉴
JBL 2414H-C 25 mm (1 in) polymer
diaphragm compression driver
improves high frequency
performance as well as system
realibility.
䉴
The advanced network topology
crossover design shapes frequency
response and delivers “coherent
summation” in the crossover
region.
䉴
High-voltage capacitors and
inductor s with massive cores and
heavy gauge wire enable the
crossover network to handle high
power without saturating.
䉴
Progressive Transition™ high
frequenc y waveguide provides
superior coverage control, reduced
distortion, and smoother frequency
response.
䉴
The rugged, acoustically superior
enclosure is constructed from
19 mm (.75 in) MDF (Medium
Density Fiberboard) using
advanced adhesives and
mechanica l fastener technology for
extreme durability and improved
low-frequency performanc e.
䉴
SonicGuard™ protects the highfrequenc y driver from excess
power without interrupting the
performanc e.
䉴
Non-resonant, all-steel handles are
used.
䉴
Attractive 18-gauge hexagon
perforate d, steel grille protects
component s from damage.
䉴
Dual-angle pole-mount socket
allows the speaker to tilt 10° for
more uniform audience coverage.
12 Inch Two-Way
Stage Monitor
JRX212
The JRX212 is a portable, twelve-inch, two-way speaker system designed
specifically for live performance stage monitoring applications. With enough
sensitivity and power handling to cut through the performance volume on
stage, the JRX212 has a smooth response so it can deliver maximum gain
before feedback. It also includes JBL’s dual-angle pole socket making it
equally at home as a front-of-house speaker.

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.
Mounting & Suspension: 36 mm, dual-angle pole-mount socket
“Frequency Range” and “Frequency Response” are based on half-space response.
“Power Capacity” and “Peak Power Capacity” ratings are based on the average and peak power capacity of product
samples subjected to a 100 hour power test using random noise with a 6 dB crest factor, in accordance with IEC
standards.
Height dimension includes feet.
