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 cover Specifications Power Rating 250 W / 1000W Frequency Range (-10dB) 41 Hz - 18 kHz Frequency Response (±3 dB) 59 Hz - 13 kHz Sensitivity (@1m) 99 dB SPL (1w/1m) Nominal Impedance 8 ohms Recommended Amplifier Power 250 W to 500 W into 8 ohms Maximum SPL (1m) 129 dB Nominal Dispersion 90º x 50º Crossover Frequency 2.2 kHz Dimensions (H x W x D) 699 mm x 460 mm x 432 mm (27.5 in x 18.1 in x 17 in) Weight 27.4 kg (60.5 lb) HF Driver JBL 2414H-C , 1" exit compression driver mounted on Progressive Transition™ Waveguide LF Driver JBL M115-8A Inputs Neutrik® Speakon® NL-4 (x1); .25in TS phone jack (x1); parallel Enclosure MDF (Medium Density Fiberboard) covered in black carpet.
