12 in. Two-Way Stage Monitor Loudspeaker System

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 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.

·       JBL 2414H-C 25 mm (1 in) polymer diaphragm compression driver 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 high frequency 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.
