seas H 382 Response curve recorded in an anechoic chamber (Free-field, 4 pi radiation) with 0.5m microphone distance. The loudspeaker is mounted in a 0.6m by 0.8m baffle. OF NORWAY TWEETER 25TA/G Cumulative spectral decay 25mm High Fidelity dome tweeter with glass fibre reinforced plastic chassis. The unit features high efficiency and smooth, extended response. Its aluminium diaphragm with critically designed shape and thickness behaves like a piston throughout the audible frequency range, resulting in good dispersion above 10 kHz. A fine mesh grid protects the diaphragm, and supports a phase plate which compensates for a slight axial roll off towards 20 kHz. A specially designed soft surround allows a low fundamental frequency and excellent mechanical linearity. 6 NOMINAL IMPEDANCE RECOMMENDED FREQUENCY RANGE Ohms 3000-25000 Hz VOICE COIL INDUCTANCE (EQUIVALENT) 160 W VOICE COIL DIAMETER 26 mm LONG TERM MAXIMUM POWER* 60 W VOICE COIL HEIGHT 1.5 mm CHARACTERISTIC SENSITIVITY (1W , 1m) 91 dB SPL MOVING MASS OPERATING POWER (96 dB SPL , 1 m) 3.2 W EFFECTIVE PISTON AREA 7.0 sq.cm LINEAR COIL TRAVEL ( p-p ) 0.5 mm AIR GAP HEIGHT 2.0 mm MAGNETIC GAP FLUX DENSITY 1.8 T FORCE FACTOR MAGNET WEIGHT TOTAL WEIGHT 0.33 g 1000 Hz FREE AIR RESONANCE 3.5 N/A 0.25 Kg 0.55 Kg * IEC 268-5, VIA HIGH PASS BUTTERWORTH FILTER: T25-101 0.05 mH SHORT TERM MAXIMUM POWER* NOTES APR.02 4.8 Ohms VOICE COIL RESISTANCE 4000 Hz 12 dB/oct.
