Ok so I'm about to go with 2 power acoustik Mofo-122X. Their round port recommendation is 4Dx12L... so i calculated 12.56 Port area (if im correct). they are made for 2cbft but I've got a roughly 3.6cbft box and I'm trying to figure out how I can just pull off 1 Square port tuned at around 35hz.
do i double the port area since i have 2 subs? do i keep the length the same? do i follow the 3:4 ratio rule (supposedly)? can anybody give me what the Length height and depth of the port should be?
