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 onstage, 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.

JBL 12 in low frequency driver with a 64 mm (2.5 in)
diameter edgewound 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.
 
Ferro-fluid cooled compression driver with titanium
diaphragm improves high frequency performance as
well as system reliability.
 
The advanced network topology crossover design shapes
frequency response and delivers "coherent summation"
in the crossover region.
 
High-voltage capacitors and inductors with massive cores
and heavy gauge wire enable the crossover network to
handle high power without saturating.
 
Progressive Transition™ high frequency waveguide provides
superior coverage control, reduced distortion, and smoother
frequency response.
 
The rugged, acoustically superior enclosure is constructed
from 19 mm (.75 in) MDF (Medium Density Fiberboard) using
advanced adhesives and mechanical fastener technology for
extreme durability and improved low-frequency performance.
 
SonicGuard™ protects the highfrequency driver from excess
power without interrupting the performance.
 
Non-resonant, all-steel handles are used.
 
Attractive 18-gauge hexagon perforated, steel grille protects
components from damage.
 
Dual-angle pole-mount socket allows the speaker to tilt
10°for more uniform audience coverage.
