AL 130 M - 8 Ohm

Art. No. 1305

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.
