Visaton GF 200 2x4 OHM

Visaton GF200 bass driver 2x4 OHM

20 cm (8") high-end woofer with black glass fibre cone, solid aluminium diecast basket and elastic rubber surround. Very flexible application possibilities due to 2 x 4-Ohm double voice coil, whereby a high-quality 8-Ohm chassis is created by series connection. The long excursion rubber surround, together with the deep-drawn pole plate, the rear-ventilated centring, the capton voice coil former and the pole core ventilation, guarantee long excursion and absolute level stability.
