Product Details

PRV Audio 12MB800 12" High Power PA Midbass Woofer 8 Ohm

PRV Audio's 12MB800 12" midbass woofer offers high output punch, a smooth midrange, and response up to 4,000 Hz. The 12MB800 is designed for use as a midbass or midrange driver in 3-way speakers. Alternatively, you can use this speaker in small ported cabinets as a woofer in floor and studio monitors.

A thick, light, and rigid paper cone is mated to a 3" aluminum voice coil former for superior heat dissipation and high power handling. A durable dual spider suspension, M-Roll woven cotton surround, and cast aluminum frame are combined for extreme durability. High output SPL car audio enthusiasts choose this driver for use in their systems when looking for a midrange or midbass that can sustain long hours of extreme operation and keep up with compression drivers and 1,000 watt, and up, subwoofers.
