You are being very kind and patient, HOWEVER, you need to recognize that it is hard to have two faulty tweeters go bad in shipping. The guy is lying to you. What could possibly have caused both to stop working? An thermonuclear electromagnetic pulse. I predict that 6 or 7 months of effort to get a pair of tweeters will result in the discovery that isnt your problem. Then you are going to need crossovers. Another 6 or 7 months go by and then you might have a pair of working speakers. Its your deal though, best.
