I have owned several sets o Magnepans..3 with the ribbons and the only concern was mine. I made the mistake of using
the vac on the grills....and damaged the ribbon with the
vac suction! Most people that have continual problems with
tweeters, I believe, have some kind of high freq. info going
through the tweeters that is frying them.....remember at best we hear up to 20k...but the ribbion can go to 40k+..
...and if your cd player or any other component is passing
high freq. noise above 20k....you can be having concerns..and it not be anything you yourself can hear.
