Hi rarebird, I'm also a home theater junkie.
You should be able to get your speaker fixed, I would be curious if the voice coil didn't also get damaged.
I need to find someone here in STL that can fix speakers, I have a pair of late 80's db+'s that need to be re-coned thanks to an ex-room mates' cats.
I have no idea how they test the frequency response of their speakers, like if you need to give them the bad speaker and a good one, so they can try to "match" the working one.
Keep us posted.
Scott
