      Visaton Speaker Driver - GF 200 - 2 x 4 Ohm High End Dual Coil Woofer
      Art. No. 1330

      Visaton GF200 - 2 x 4 ohm High End Dual Coil Woofer.
      Visaton GF200 - 2 x 4 Ohm High End Dual Coil Woofer

       

      Characteristics and Sound Properties
      20 cm (8") High-End dual coil woofer with black glass fibre cone, solid aluminium die-cast basket and elastic rubber surround. Designed for multi-purpose applications due to 2 x 4 ohms double voice-coil, with excellent properties as 8 ohms drivers in series configuration. The long stroke voice-coil in conjunction with the extended rear pole plate, the vented damper, the vented magnet and the capton voice-coil carrier guarantees long strokes and highest power handling.

      Possible connections:-
      - (1) one voice coil not connected = 4 Ohm
      - (2) both voice coils in series = 8 Ohm
      - (3) both voice coils in parallel = 2 Ohm
