Ok, according to the two latest replies my 14" is the same. I just started to wonder, because if you measure the actual cone diameter with foam ring, it's not more than a 12" woofer. But if you measure across the frames edges on the widest part, is 14".
I don't really like that kind of tricky way to boost a woofers size. You can if you like then have a 4" cone with a 3" wide mounting frame, and call i a 10" speaker....
