I like my M80s better when I run my sub with them, the low end has more feeling to it, not that it sounds bad with the M80s alone, the 80's produce alot of bass for a floorstander, just a personal preference.

I would suggest looking at buying a new sub over repairing the old one. As Mark said, new subs, IMO, are much better, they reach much lower and I think they play tighter and not as boomy as was the case 10-15 years ago.
