Making an enclosure for an idmax12 v.3

ok u want one dat'll be around 16inches tall. so u'll want to minus off 0.75 from each side cus of da mdf thickness and this will end u up wid 14.5inches tall. now like i said u'll want to divide 12 by 14.5 which gives you 0.8inches thickness. so the internal dimensions of the front of ur port will be 14.5 by 0.8 inches. i've got summit better, now remember this was in terms of a 4 inch diameter port so if we up da diameter to 5inches and pie this we'll get 15.7.

now 15.7 divided by the height which is 14.5 comes to 1.08 inches. the length of the port has also become enlarged so the new dimensions are 14.5inches tall, 1.08 inches wide and 15inches deep.

now we have hit a slight problem, ur box is only 13inches deep and we require 15 inches. so from this we carry the port on to the end of the box. remember this ur port will be 1.08 inches wide, so beofre ur port reaches a dead end at the end of ur 13inch deep box we need to make a bend(the side of the port needs to be a a parallel distance from the side of the box which in this case is 1.08 inches). now after this bend u will add the extra two inches on. i will post a diagram
