There's a guy on the forum, here that can probably help with the tweeters.
He posted in a thread called something like "most embarrassing audiophile moments". He worked in an audio shop and there were a pair of demo speakers that had the tweeter(s) pushed in. He decided he would fix it by gently... sucking on it to get it back in position. He looked around to make sure no one was nearby said just as he got on his knees and put his mouth on it... (I can barely type because I'm laughing so hard)… that this really hot chick walked in and saw him!!! Dude, that was classic! It sounds like something that would happen to me.
Sorry, I know my post doesn't really help, but if it makes anyone laugh like I did, it was worth it.
