i have a enclosure that has 3.22 cubft after sub displacement. i wanted to do a kerfed port tuned to 47hz with about 96 square inches of port . can someone help me out on the length. i was thinking about doing the port 18" long by 5.25" wide.
i got the 18" because that is the size of the box from one side to the other ( inside walls ). the 5.25" is what it takes to make it 94.5 sq inches.
i figured it out but then when i add the port displacement the box volume goes down and the port length gets longer. then if i make the port longer it adds more to the port displacement. what do i have to do ?
am i missing something here. i have done it before but i just cant figure this out .... i think i am getting stupid.
i appriciate all your help. THANKS
