Probably an extremely stupid question but do tweeters go off? I'm probably a stupid old audiofool but I'm looking at ways to improve my IMF super compact II's I've replaced the midrange driver to great effects but I have read stories of the ?ELAC tweeters failing after a while. Falcon do a replacement and I wonder if it might be worthwhile and investment in a pair of new tweeters? Take the piss if you like Gentlemen, all replies and suggestions greatly accepted. :)
