I would like to build a ported box that is 1.8cuft tuned to 32hz. Sub is a Critical Mass UL12.

This is the picture of what I would like the side of the box to look like. As you can see Height = 24", Depth = 13" (typo in the picture, could use up to 14" if necessary), and Width is TBD. The depth at the top is variable, as well as the angle and length of the other side. The width can be up to 30" but I would like to keep it <24". All measurements should take into account that I will be using 1" MDF for the face (flat front area), and the woofer hole is approximately 11.68"

I can't find woofer displacement right now, I am still looking for it so if anyone has it, please chime in

Does it have to be 24" high, where is the port going, square or aero port(s)?

No it can be less than that, but not more. Square port, and on top of the box where the variable top depth and the variable angle meet, or on bottom where the 13" depth and the variable height meet; whichever is easier for design sake
