W 100 X - 2 x 4 Ohm

Art. No. 9049

10 cm (4”) woofer with low resonant frequency and compact size. The wide and elastic rubber
surround allows for a large excursion. A 2x4 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: (1) one voice coil not connected (2) both voice coils in series (3) both voice coils in parallel
