Okay..so i got an idmax. Hurray! Now im tryin to build a slot port enclosure for it. The enclosure specs says, 2.55 gross cu. ft. tuned to 28hz with 4" i.d. by 15" long. After alot of researching and understanding how ported enclosures are made, i have came up with these calculations: 36" width, 15" height, and 11" depth(i might change around the depth and width a lil). The port slot will be 2" by 9.28" (prolly more like 9) by 10". What do ya guys think?
