Visaton TIW 400 DS 2 x 4 Ω
40 cm (15") High-End woofer with black cellulose cone, large magnet and heavy aluminium die-cast basket. Extremely high power handling due to 60 mm voice-coil, capton voice coil carrier and magnet vent. Univesal connection possibilities due to the double voice-coil (2 x 4 ohms) allowing the unit to be conncted up for 2 ohm ore 8 ohm use.
