JBL used that setup in their big classic studio monitors with huge success.

Yes, JBL it's great design.
Many times, when you are running the project and looking at your concept, if you need more SPL from the sub (see, SUB is supposed to go low and not as good in SPL) you then get two subs (15"). Most of the times 1x driver will be difficult without attenuating the 10". Have that in mind...

Talk it's easy.
All I know is that these JBL projects linked above were possible. It should ring you a bell. :D

Did any of these people offer an explanation as to Why they Think it isn't possible? If so, please tell us their explanation. I'm sure it'll be humorous.

well....
actually they didn't offer any explanation, they just told me mid and woofer should same size...
but creative use a large woofer with small mid, so i was confused...

What drivers are you using, besides their size, if that is of any importance for you. What alignment (recommended box system/type and size or interior volume) for the woofer are you using?
