do i just split the normal box volume directly in half? or is there a formula i need to go by? probably doing a dual chamber, instead of mounting subs face to face. the air between the 2 subs doesn't matter much on space.....i don't think.

for 2 15's. probably some cheap MA audio's at first, then i'll buy better 15's after messing with this design some. ported chamber-2.5 cubes, tuned to 36 hz. sealed chamber is just under 1 cube. using cheap 15's at first to see how it works. if i get more efficient 15's, i can drop the ported chamber to around 2 cubes. noone has ever done any push pull isobaric setups?
