Haut-parleur subwoofer Visaton TIW300-8OHM
[TIW 300-8] Avis/Critiques
30 cm (12") high-end woofer with a black cellulose diaphragm, large-format magnet arrangement and a massive aluminium diecast basket. 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 spider from behind) losses and flow noise are minimised.
The combination of the voice coil carrier made of capton and the large 65 mm voice coil allow extremely high volume levels.
