The JBL JRX212 is a portable 12" 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 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. The JBL JRX212 delivers the performance and prestige JBL is known for at an affordable price point.

Progressive Transition™ Waveguide
Just one example of JBL's innovation is the PT™ Waveguide design. For decades, horn designers were faced with trade-offs between well controlled coverage, low distortion, and good frequency response. JBL developed proprietary algorithms which give their PT Waveguides the best performance in all three areas.
The JRX200 Series doesn't scrimp on the hardware either. All the JRX models use tough, non-resonant all-steel handles with big, beefy bars. And the entire baffle (not just the woofer) is protected by an 18 gauge steel grill.
All woofers and compression drivers used in the JRX200 Series are manufactured in Northridge, California by JBL Professional.
Competitive systems typically use particle board construction and rely entirely on glue to hold it together. For the JRX200 Series, JBL selected a more rugged and acoustically superior 3/4" MDF material for the enclosures. And to make sure they stay together, they constructed them with advanced adhesives and closely spaced mechanical fasteners. Not only are the cabinets rugged, but the denser enclosure walls are more rigid, delivering better low end as a result.
Feedback, dropped microphones, pushing the amps into clipping—all these things can quickly destroy even the best high-frequency drivers. That's why JBL JRX200 speakers include SonicGuard™ protection. SonicGuard circuitry absorbs excess energy without interrupting the performance. No circuit breakers to reset, no fuses to replace, and no "poly-switches" to degrade sound quality.
"Power Handling" and "Peak Power Handling" 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.
