This trapezoidal, 15" speaker system is at home in live sound, dance music and speech reinforcement.

Features :
JBL 15 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.
# Ferro-fluid cooled compression driver with titanium diaphragm improves high frequency performance as well as system reliability.
The advanced network topology crossover design shapes the frequency response to deliver 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 (.75 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 perforated, steel grille protects components from damage.
Dual-angle pole-mount socket allows the speakers to tilt 10 Degrees for more uniform audience coverage.

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 our PT Waveguides the best performance in all three areas.

Hardware
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.

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, 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 bass response as a result

SonicGuard
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 audio fidelity.
