Resumen del manual
A four inch copper wire voice coil with very high thermal capability and a ventilated magnet assembly allows a low power compression. A very low distortion figure is obtained using a double spider design and dual demodulation rings in the magnetic path. Proprietary water-proof cone treatment for safe use in adverse climatic conditions. £ 0 w o a co Specifications Nominal Diameter 460 mm (18 in) Nominal Impedance 8 Q Minumum Impedance 6.1 Q Power Handling (40 -400 Hz) Nominal1 1000 W Continuous Program2 2000 W Sensitivity (1W/1m)3 97 dB Frequency Range 30-1500 Hz Voice Coil Diameter 100 mm (4 in) Winding Material Copper Former Material Glass Fibre Winding Depth 25 mm (1 in) Magnetic Gap Depth 12 mm (.47 in) Flux Density 1.1 T Also available in 4 Q, data upon request Thiele & Small Parameters4 Fs 34 Hz Re 5.2 Q Qes 0.33 Qms 5.3 Qts 0.31 Vas 227 dm3 (8.0 ft3) Sd 1210 cm2 (187.6 in2) no 2.5 % X max ± 9 mm X Var ± 11 mm Mms 201 g Bl 25.8 Tm Le 2.0 mH Mounting and Shipping Information Overall Diameter 460 mm (18 in) Bolt Circle Diameter 440 mm (17.3 in) Baffle Cutout Diameter 422 mm (16.6 in) Depth 188 mm (7.4 in) Flange and Gasket Thickness 16 mm (5/8 in) Net weight 13 kg (28.6 lb) Shipping Weight 14.8 kg (32.6 lb) Shipping Box 520x520x240 mm (20.5x20.5x9.4 in) 1 2 hours test made with continuous pink noise signal (6 dB crest factor) within the specified range. Power calculated on rated minimum impedance. Loudspeaker in free air. 2 Power on Continuous Program is defined as 3 dB greater than the Nominal rating. 3 Applied RMS Voltage is set to 2.83V for 8 ohms Nominal Impedance. Average SPL from 200 to 1200Hz. 4 Thiele-Small parameters are measured after a high level 20 Hz sine wave preconditioning test. ©...
