PROBLEM SOLVED temporarily: I am impatient, but actually very impressed by the very quick responses. I had tried the vacuum on my own without luck: too porous. However, thin pins bent into a reverse curve with hook at the working end penetrated easily and with out damage: one needs 2-3 pins at once to help keep the partially restored shape while working on other residual areas. Using two people also helps. Only minor creases persist, but these may allow the problem to return.
Is there a source for Klipsch repair parts?
I am in central IL. We are downsizing. I also have a pair of pristine Cornwall II's that I would be interested in selling, but due to the weight, e-bay seems to be a stretch. Meet Sophie: I apologize for the creepy original.
