8″ B&C Woofer FMB51 8Ω|16Ω
The FMB series mid-bass woofers from B&C Speakers offer acoustic designers a new range of high efficiency, wide bandwidth alternatives that are not currently available in the B&C range. These full-featured transducers incorporate lower cost ferrite motors, inside/outside wound copper clad aluminum wire voice coils, weatherproof impregnated paper cones, and a symmetrical inductance profile. The FMB Series is especially well suited for two-way loudspeaker enclosures.
