21 or 2 15s?

Ain't gonna be much louder with 2 15's unless they are a lot more efficient. Surface area is pretty close. Actually might go to the 21 because it only has 1 surround.
The 21 will prolly need more volume than the 2 15's though. So make sure you have the space available. 21 should play lower louder as well. So....really in the end, it is up to your wallet and wants.

It'll be about the same as 2 ia 15's.

That's pretty simple, I'd like to see some kind of kerfed design or something.
