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.
• 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 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™ 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 perforated, steel grille protects components from damage.
• Dual-angle pole-mount socket allows the speakers to tilt 10° for more uniform audience coverage.
