Yea ..... But .....
Here's my (tentative) plan:
Use a widerange driver to get down to say 100Hz.
So a 100Hz driver with a Q of 1 will give a flat
response (Q=~.7) on a 100Hz baffle.
Then add a 'helper woofer' to extend down an octave.
(rolled off on the high end with a 12db/octave passive
network)
(a driver with a Q of 2 @ 50Hz on a 100Hz baffle is
flat down to 50Hz)
Thus the need for a fairly good definition of baffle
cutoff since the baffle is used as a crossover element.
