If you have 15 cubes, why not just use 4 15"s at 30-40hz.?

no if the box is tuned to 30hz it dosent matter if u drop 3 15s or 12 10s in it still 30hz. there is only the matter of the displacement of the sub in the box but what is that in a 5cf box .1-.18,lol.

the thing you should be looking at though is that isnt much sq" of port for the cf of the enclosure. say if you wanted to put in 2 entry level 15s you would be fine. if yo want to put in 2 high end 15s ur gonna hear port noise with the amount of air that is going to be moving...
