PLEASE READ: The unique size 8″ Polk woofers have been discontinued, so we had these custom made for us designed from the Polk Audio woofers. These are new current production stock. The parameters were closely copied to ensure similar output level and sound. In comparison to the original, it is very close. Overall, it is a great reproduction for many of the Polk Audio 8″ woofers. It is a perfect drop in fit with no modification needed to the cabinet. The screw holes match up perfect. This unique aftermarket woofer has a steel basket, polypropylene injected cone, butyl rubber surround and a standard ferrite non-shielded magnet and a new foam gasket for a proper seal to the cabinet. Our woofer does not have a shielded magnet. Some Polk models like the MW8002, MW8003, MW8103 and MW8201 have a shielded magnet, but a shielded magnet only matters if it is near an old tube style TV or monitor. Also, some Polk woofers like the MW8003, MW8004 and MW8201 came out of subwoofers and these woofers have large 4.25″ poly dust caps. Please note our replacement woofers have the standard 1.5″ dust cap.
