Here is the recomendation form parts express :
"The volume I would recommend for this driver is 0.2 cubic feet with a 1.5" diameter, 1.5" long port for a tuning frequency of 91 Hz and an F3 of 71 Hz.
but this is for each speaker into a 0.2cf."
So ,if both drivers see the entire volume in the case of no divider , can I just add 2 ports and it will be the recomended ported 0.2cf version?
