Wayne,
I appreciate your clarifications... I am also against use of different subs simultaneously. I don't know if you are aware of the HSU new mid bass module, which has a freq. response ranging from 40 and up...And everybody's beginning to follow a new fashion of adding a MBM module in the nearfield to have additional headrooms and punch in th mid bass region. I even saw people add an MBM to an SVS Pb12+/2
(the SVS is already very dynamic in the midbass and stronger than freq. below 20).... Pls see these threads:

I wonder what happens at high listening levels where one would have ample headroom in the midbass and being near compression at lower frequencies... sound will get muddy IMO
am I nuts?????
