hello i have designed a sub box for my 12" exile S12. the problem is im not sure where to cut a port hole or how big it should be can anyone help me out? the box is 28.25 in wide, 16 in high, bottom depth 13.5 in , and top depth is 10.75 in. i used 3/4 in MDF. im pretty sure the inside volume is 2.273

do you wanna do an aeroport or slot port? you cant just cut a hole in your enclosure and call it a 'port'

 

With a slanted face, it's going to make porting tricky. I'd maybe go aero to the side???
