Description: GF 200 - 2 x 4 Ohm

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

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
