JBL JRX115 15" 2-Way PA Speaker System

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.


JRX100 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.

JBL Drivers

All woofers and compression drivers used in JRX100 are manufactured in Northridge, California by JBL Professional.

Enclosure Construction

Competitive systems typically use particle board construction and rely entirely on glue to hold it together. For JRX100, 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 JRX100 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 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.
