Industrial alarm compression driver AL 130 M

neodymium

13 cm (5") High End midrange driver with stiff, anodized aluminium cone, solid aluminium die-cast basket and elastic rubber surround. Extremely low mechanical and electrical losses due to vented pole plate and vented damper. Capton voice-coil and impedance control ring. Due to the short voice-coil, the efficiency, compared to the AL 130 - 8 Ohm, has been increased by 2-3 dB above 500 Hz. Suitable as midrange driver in 3-way High End applications for a frequency range up to 5000 Hz. Rated power - 60 W Maximum power - 90 W Nominal impedance Z - 8 Ohm Frequency response - fu–8000 Hz (fu: Lower cut-off frequency depending on cabinet) - . Mean sound pressure level - 90 dB (1 W/1 m) Opening angle (-6 dB) - 94°/4000 Hz Excursion limit - +/−5.5 mm Resonance frequency fs - 57 Hz Magnetic induction - 0.95 T Magnetic flux - 450 µWb Height of front pole-plate - 6 mm Voice coil diameter - 25 mm Height of winding - 12 mm Cutout diameter - 115 mm Net weight - 1 kg D.C. resistance Rdc - 5.4 Ohm Mechanical Q factor Qms - 4.39 Electrical Q factor Qes - 0.52 Total Q factor Qts - 0.46 Equivalent volume Vas - 9.1 l Effective piston area Sd - 79 cm² Dynamically moved mass Mms - 7.4 g Force factor Bxl - 5.6 Tm Inductance of the voice coil L - 0.8 mH
