The 6MBX44 6" mid-bass woofer from B&C Speakers offers acoustic designers a high efficiency, wide bandwidth driver capable of surprising output levels. This full-featured transducer incorporates a lightweight neodymium motor, inside/outside wound copper clad aluminum wire voice coil, weatherproof hydrophobic paper cone, and a symmetrical inductance profile. Everything about this driver has been designed for reliable and consistent low distortion output even when driven to its limit. All MBX Series drivers are especially well suited for 2-way loudspeaker designs.
