I can't remember what the exact problem was with the 15's that some people had go bad. Some have said the 12 didn't have that weak point, whatever it was. It makes it all too confusing when it's just labeled defective.
Is there a weak point in the sub? Or maybe it's power handling is rated too high? I love the looks of those subs and would maybe consider buying one, but wouldn't try to with a story that still doesn't seem to have an obvious conclusion. And I'm not asking for a pissing contest or any finger pointing or any blame, just info about that sub and that is all.
