JRX112M
Key Features:
䉴
JBL 12" low frequency driver with
a 64 mm (2½ in) diameter edge-
wound ribbon 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
Ferro-fluid cooled compression
driver with titanium diaphragm
improves high frequency
performance as well as system
reliability.
䉴
The advanced network topology
crossover design shapes frequency
response and delivers “coherent
summation” in the crossover
region.
䉴
High-voltage capacitors and
inductors with massive cores and
heavy gauge wire enable the
crossover network to handle high
power without saturating.
䉴
Progressive Transition™ high-
frequency waveguide provides
superior coverage control, reduced
distortion, and smoother frequency
response.
䉴
The rugged, acoustically superior
enclosure is constructed from
19 mm (¾ in) MDF (Medium
Density Fiberboard) using
advanced adhesives and
mechanical fastener technology for
extreme durability and improved
low-frequency performance.
䉴
SonicGuard™ protects the high-
frequency driver from excess
power without interrupting the
performance.
䉴
Non-resonant, all-steel handles are
used.
䉴
Attractive 18-gauge hexagon
perforated, steel grille protects
components from damage.
䉴
Dual-angle pole-mount socket
allows the speaker to tilt 10° for
more uniform audience coverage.
The JRX112M 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 JRX112M 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.

1.
“Frequency Range” and “Frequency Response” are based on half-space response.
2.
“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.
3.
Height dimension includes feet.
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 rea-
son, 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.
