Tri-Chamber 4th Order Question

[robbierob02]

im about to design a box for 4 10's in the 4th order and thinking of doing separate ported chambers for each pair of subs. My sealed chamber will roughly be 4.8 cubed so if i do a 2:1 ratio then the way i see it is both ported chambers need to equal 9.6 together correct? so the box should be 4.8 sealed and each ported chamber needs to be 4.8 cubed also right? probably a dumb question but thought i'd verify this with you guys before setting myself up for failure

Ive never seen this done, what would be the gain or benefit in seperate ported sections?
