But anyway, as to the current problem, I just don't think there is any magic answer. Sure, the resistors may be a partial solution, but maybe Axioms are just not the best speaker for jbsengineer. Good luck.
Out of the 140 or so (thus far) very helpful replies to this persons obvious speaker troubles this is probably the single best result for him/her at the moment. Every probable solution has been exhausted by numerous knowledgeable members, including the removal of tweeters, adding resistors and so forth?
Maybe it's time to raise the white flag.
