Thumbnail Filmstrip of W 100 X - 2x 4 Ohm Dual Coil Woofer Images
Visaton Speaker Driver - W 100 X - 2 x 4 Ohm
Art. No. 9049
Characteristics and Sound Properties
10 cm (4") woofer with low resonant frequency and compact size. The wide and elastic rubber surround allows for a large excursion. A 2x 4 Ohm dual voice coil allows 2, 4 and 8 Ohm operation, as well as stereo connection, for example via the rear channels of a car radio. The easy-to-install and visually appealing metal basket make the W 100 X a versatile subwoofer for hi-fi and industry.
Possible connections (see specs below):
- (1) one voice coil not connected
- (2) both voice coils in series
- (3) both voice coils in parallel
