I bought a pair of used Energy C-1s on eBay. They sound great, but one of the tweeters is dented. I was hoping to use these without the grills, so I am trying to get into the speaker to push the tweeter back out. I unscrewed the faceplate, but it is still holding on tight...must be glued. I then went in from behind, moved the insulation out of the way, but saw that the tweeter is in its own self-enclosure. Therefore, I can't reach it from behind the speaker. Can any speaker experts out there help me? Thanks.
