Speaker Repair Place

I'm looking for a good speaker repair place here in Houston. I have obtained my parents' old Bose 601s (1977), but I haven't listened to them yet. I know that while we lived in Norway, the sound got really bad on them. Then when we moved here, they were good. But I'm not sure -- I'm gonna try them out tomorrow and see, but if I need to replace the foam or anything else, I'd like to know of a good speaker repair store where I could get them checked out.
