Klipsch driver help needed please


I was wondering if you might be able
to give me some suggestions on Klipsch drivers.
I have a midrange (squawker) that is sort of buzzing/distorted during some but not all passages.

Does it sound like a blown driver/squawker?? Can they be
blown??

These are 1989 La Scalas (midrange) (K 55-M model #)

Anyway, if anyone has any suggestions, they would
be greatly appreciated.

BTW...I have been looking for some contact info
for Bob Crites.
Do you happen to know it?
Firstly I agree its probably the diapraghm which can be replaced. If you are going to get a new crossover I have great things about the ALK to replace the AA. One thing you can't do at a reasonable price is get a new driver from Klipsch they still make the La scalas and have them but when I asked them for tweeter for my heresies (I have La Scalas as well) they wanted $275 for the pair so I got a whole pair on ebay. See my classifieds here on Agon if anyone wants the the tweeter was O.K.- You can get K55 drivers on ebay as well individually they actually have a category under consumer electronics for drivers also look under speakers and vintage speakers which has a lot of cool drivers. Now would somebody look at me JBLC36 question?
