I just purchased an eden 210XLT (haven't had a chance to play it yet), and there appears to be a small wrinkle near the edge of the cone on both speakers. It doesn't go all of the way around, only about 20% of the way or so. Is this something I should worry about? Other than playing through the cabinet to listen for any problems, is there any way to test this for damage? Is this a normal thing, or a sign of problems to come? If this is an issue, is it something I need to send to Eden, or is there a better (more affordable or more reliable) speaker repair company to deal with?
