Visaton AL 170 8 OHM

Visaton AL 170 8 OHM

17 cm (6.5") high-end mid/bass driver with stiff, anodised aluminium cone, stable aluminium die-cast basket and elastic rubber surround. Lowest mechanical and electrical losses due to pole core ventilation, ventilated centring, capton voice coil former. Very large linear travel due to long voice coil. Especially suitable as bass-midrange driver in high-quality 2-, 3- and 4-way high-end combinations up to approx. 2500 Hz.
