The mid speakers can be the exact same size between the Sedan and the Coupe if BSW really wanted them to be...
OK what I'm saying is;
1. You're right that the stock sedan & coupe mid are the same. Both are VERY shallow.
2. The stock mid in the sedan is replaceable with a deeper speaker. The mid in the coupe is not. There just isn't any extra depth available in a coupe door cavity.
3. From what I see on the BSW mid, it would need to be roughly 3/4" more shallow to fit in a coupe due to depth to window mechanism restrictions.
Unless you don't want your windows to roll down all the way
