MW Audio MW-7000: 7″ Polk Audio Copy Woofer

This woofer is a great replacement for many Polk Audio woofers.

Here is the list of woofer models and what cabinet models they go into:

4 ohm woofer models are:
– MW7000 : Goes into S4, S6 and more
– MW7008 : Goes into AWM5, AB805 and more
– MW7009 : Goes into RT5, RT8, RT20 and more

8 ohm woofer models are:
– MW7010 : Goes into RT12 and more
– MW7100 : Goes into LS50, LS90 and more
– MW7101 : Goes into several models.

These are new current production stock. The unique size 7″ Polk woofers have been discontinued, so we had these custom made for us designed from the Polk Audio woofers. 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 7″ 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, 1.5″ dust cap and a standard ferrite non-shielded magnet. Some Polk models like the MW7009 have a shielded magnet, but a shielded magnet only matters if it is near an old tube style TV or monitor.
