The JBL JRX118S is driven by a massive JBL 18" woofer with a cast frame and 3" voice-coil. It's rated at 350 watts (continuous) and 1400 watts (peak) - and
that's based on JBL Professional's 100 hour torture test.
Progressive TransitionTM Waveguide
Just one example of JBL's innovation is the PTTM 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 our 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 grille.
All woofers and compression drivers used in JRX100 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 JRX100, we selected a more rugged and
acoustically superior 3/4" MDF material for the enclosures. And to make sure they stay together, we constructed them with advanced adhesives and closely
spaced mechanical fasteners. Not only are the cabinets rugged, but the denser enclosure walls are more riged, 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 SonicGuardTM 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.
