There are different ways to skin a cat. You certainty need a low FS. There are two approaches you can take. You can use a low QTS with a lot of Xmax and use EQ to compensate for the quick roll off. Or you can use a driver with a High QTS (.7+) to get a response well down near the FS of the driver.
The latter generally limits your selection to drivers with a small xmax. My advice is if you are set on going IB with 12 inch drivers, do the install and try it. If you got a lot of excursion to work with (and obviously a lot of cone area), you should get plenty of output. If they don't work for that particular alignment, sell them and try something else
