MiniMarty dimensions please help

Hi, I am about to start cutting the wood to build 2 minimartys but I found 2 different blueprints and I need to know witch one is right before cutting. They have the same external dimension but different port size. 1 set show a port height of 3 inches and the other one show a port height of 2.5 inches. They also vary in length.
Port set #1: 3 x 47.5
PORT set #2: 2.5 x 44.75

Please advice in order to start the project. Thanks.

You probably want to decide the port dimensions based on the specific driver and amp you are have, using WinISD. You want to keep the first port resonance high enough that it doesn't reduce output from the sub, and you want the port cross section large enough so you don't hear audible chuffing at max power. Both can depend on the particulars, so you really want to model it.

Go with the revised cutlist (2.5 x 44.75).
