JBL JRX-112 M

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.

Features

JBL 12" low frequency driver with a 64 mm (2½ 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™ highfrequency waveguide provides superior coverage control, reduced distortion, and smoother frequency response.

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.

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.
