Audiopipe

I'm trying to design a 4th order bandpass box for two audiopipe 15s but don't know which air space to use the subs I have call for 3cube ft each in a sealed box and 3.5 cubic ft each in a ported box. I have heard people say 2:1 ratio but is it off of total of 13 cubic ft or the seals or ported . I guess what I am asking is what cubic ft should I use for each sub sealed and what total cubic ft for the ported section and what size should the port be for say 32hz please help!!!
