so i'm going from the plans of the box that is 2.9cu ft at 33hz for 2 10L7's and am going to change the tuning to around 36 hz. the box dimensions are 40.5 wide x 13.5 tall x 16.5 deep. I WANT TO CHANGE THE PORT LENGTH TO 35 hz--- 12x2" port 25.5 " long for each side. is that correct?
the origional plans are here---->
