Visaton TIW 300 8 OHM

Visaton TIW 300 bass driver 8 OHM

30 cm (12") high-end woofer with black cellulose cone, very large magnet system and massive aluminium diecast basket. Multiple ventilation of the voice coil (pole core drilling, holes in the pole plate, openings in the aluminium diecast basket for rear ventilation of the centring) minimises losses and flow noise. The capton voice coil former and the large 65 mm diameter voice coil allow extremely high loads.
