Hey 'soon to have bass':heehee:
As far as that answer- I can't tell you, but two 12"s will likely have more displacement in the form of cone area and travel combined. Will you go ported or sealed-huge difference in size, and two 12"s will need quite a bit of room ported; so if you don't have any size issues, have placement flexibility, desire greater output spl, and for music only I'd recommend the 12"s in nice sized ported boxes...with plenty of power, of course!
Another option is to wait on some HTS'ers that are working on a 'crazy' exodus shiva bass horn behemoth .
