VISATON AL 170 8 OHM

17 cm (6.5") High-End low midrange driver with stiff, anodized aluminium cone, solid aluminium die-cast basket and elastic rubber surround. Extremely low electrical and mechanical losses due to vented pole plate, vented damper and capton voice-coil. Extremely long cone displacement due to long stroke voice coil.
Suitable as low-midrange driver for 2-, 3- and 4-way high-end applications up to 2500 Hz.
