B&C 6MBX44 6.5-Inch Speaker Driver - 200W RMS, 8 Ohm

The B&C 6MBX44 6.5-Inch Speaker Driver offers 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 lightweight neodymium motors, inside/outside wound copper clad aluminum wire voice coils, weatherproof impregnated paper cones, and a symmetrical inductance profile. The MBX Series is especially well suited for two-way loudspeaker enclosures.
