View Full Version : Figuring out dimensions for vented

06-19-2006, 08:31 PM
I want to build a vented enclosure for my 2 IDMAX 12s but dont know how to calculate or figure out dimensions for the slot port, I have taken measurements and I came up with the following specs; 17.5"T x 36"W x 19.5" will be 5.84 then subtracting the sub and port displacement should bring it to about 5.5 but I want it to be the best performance which is 2.55cu ft @28hz how can I accomplish this?
