Will a 15 inch and 10 inch subwoofer sound good back to back in a single box?

I have a 15 inch jl audio in a good sized square box and I want to put a 10 inch sub in the same box. I only have room to put a 10 in the back if the ox and the 15 is in the front. I have paddin on th inside. I just want to know if the 10 and 15 back to back will sound good. P.S. I have a 1200 watt amp so im not worried abut power!
