I finally got my 240Tis up and running tonight after about 2 years of parts collecting and waiting for funds. Everything plays, nothing vibrates or rattles, but one tweeter is obviously quieter than the other. I replaced the switches in the crossovers and both networks measure the same, as does the DCR on the tweeters. I've read that there is some foam inside the tweeter that can fail over time. Could this cause my problem? Could someone point me to a walk through on how to repair it?

These are ebay tweeters and pulled-from-a-barn crossovers, so I've never played any of this stuff before tonight. I do like the one speaker that appears to be working correctly.
