Do you have a damaged/worn out/rotted foam M&K 4ohm subwoofer? This is a great replacement! Why refoam or repair your existing driver when you can replace it with a new driver for only $20! This fits in exactly the same size hole, but has a slightly larger outside diameter (about 1/4") than some of the M&K drivers, so make sure it will fit properly before ordering. Overall diameter (width) is 12 1/4".
This is a very high quality MA Audio 12" 4 ohm subwoofer pn HB3X12RW, which has a single voice coil, stamped steel frame, huge magnet, and a vented pole piece. DCR 3.2ohm
