Ok I figured out that Alpines spec on the box which is the 1ft^3 with the 3x12 port gives a box that is tuned to about 36.5hz.

To make things simpler for me (I am so damn confused right now lol) Do I take a 1ft^3 box, figure out the tuning frequency for that, add the port volume and the port wall volume and the sub displacements to initial volume and build a box that size?

So if I have a 1ft^3 box + .05ft^3 port giving me 36hz + .05ft^5 subdisplacement + .05ft^3port wall, I build a box that is 1.15 internal volume. Once all the displacements of everything else are brought into effect, I will have a box that is 1ft^3 and tuned to my desired frequency?

BTW all those numbers I used it that example mean nothing and were just for example. The only thing that stands is I want a 1ft^3 box tuned to 36hz
