Visaton TIW 200 XS 8 Ω
20 cm (8") High-end woofer specially for use as a small subwoofer. The extra-wide elastic cone, the long voice coil and particularly large magnet arrangement give this speaker extremely long excursion. Thanks to the multiple venting of the voice coil (pole piece hole, holes in the pole piece plate, cutouts in the aluminium diecast cone to vent the centring unit from behind) losses and flow noise are minimised.
