AL 200 DV 2x8 OHM

20 cm (8") High-End woofer with double voice-coil, stiff aluminium cone, solid aluminium die-cast basket and elastic rubber surround. Extremely low mechanical and electrical losses due to vented pole plate, vented damper and capton voice coil carrier. Fast pulse response due to light weight aluminium cone. Suitable for subwoofers, which should be connected in stereo mode.
