12 inch Mavin Drop in replacement for M&K 8 Ohm Dual Voice Coil Subs, V1B, V2B, Some V3B, Volkswoofer

This is a drop in replacement for the M&K 8 Ohm Volkswoofer Series of Sub Woofers, Mavin's Own 12" High Performance Driver. Works for the V1B, V2B, and some of the V3B Volkswoofers that used the dual voice coil driver.

Rated to 250 Watts RMS with a Minimum SPL of 90 dB
It has a Practical Frequency Range from 25 Hz to 5,250 Hz
Rubber Surround and Heavy Magnet Structure High End Quality at a Mid Level Price.

Simple process to replace any of the standard M&K 12" Woofers, just undo the screws pop out the old woofer, disconnect the wires and do the reverse to complete the install. Note to help seal and maintain an air tightish cabinet, I grab a bottle of Rubber Cement and coat the recess lightly. Easy clean up and does a really good job, once dry, you just rub it offf with your finger.

In 5 minutes you're done, still better, that dead sounding M&K Sub will spring back to life with performance like that of a New Sub.
