anyone ever used this box calculator before? box calculator

im having trouble figuring out the port as on my cut sheet it says on a 30x17x9.5 box= 2.05 cubes. tuned to 32.34 hz that my top/bottom port is a 2"x 1.65" cut? i just dont understand this, as this number seems way too small to be an actual port. it is a 3 common wall port as well. any help would be greatly appreciated!

Take a screen shot and post it. Will be easier to see all the dimensions.
