Bill, is it in one speaker or both? If Wayne's offering to test them, send 'em to him! If there was a violin in the room, your tester would skedaddle (even tho most all strings are now synthetic)! It would seem strange if both speakers got the same little "issue" at the same time. Good luck! I'm in the middle of soldering some xover's for a set of these for a good friend. He liked mine so much he made himself some cabs and I'm doing the electronics for him. The cabs are something!
