Default IB gurus: Tempest vs. BPD 1503 for organs and explosions

Assuming four drivers mounted facing into 2200 ft3 HT with 1200 ft3 room behind, ignoring all room effects for the moment, assuming 500w/driver, no EQ, the drivers all equidistant from and aimed at a listening position 12 ft away, how would you expect the spl curves from 16-40 hz to compare at that position?
Would the BPDs start to roll off significantly higher? In both cases, where would you expect to be -10db vs level at 25 hz?
If the four BPDs were reduced to two with 1000w/driver, how would the answers change?
If the two BPD 1503s were replaced with 1803s?
How would addition of BFD-type EQ change the above?

thanks in advance for any and all answers.
V.

Default Thanks ThomasW.

Since I really wanted to hit all the IB gurus and could not be sure they all read each forum, I imposed on the collective bandwidth; mea culpa.
