I have a pair of ElectroVoice Interface C 's with Equalizer which I purchased new . These speakers have been used very little over the last 15 years and for the most part have been stored in a closet. (Why is another story) I have been trying to determine if they have any value. I have found very positive reviews on Interface D's. But the one set of C's I have seen reviewed here look nothing like mine. Mine have the same warning about hearing damage as the D's and the equalizer is a C/D model. Anybody know anything about these speakers?
