Ah I mean technically sorta right? But the difference between 12 and 14 mm really isn't going to have any significant negative impact. You will need to swap around some tuning parts possibly.
Most people that fuck up bings swap them around and have mismatch tuning parts, they run like crap, and they say things like putting a 14 on a 12 hurts the midrange when it's really just tuned wrong.
I have a perfectly tuned airsal with a 14 Bing at home, I have been meaning to pull it apart and see what's in it, next chance I get I'll try to remember to write it down for ya.
