[QUOTE="tommyk90, post: 5449443, member: 545293"] Here is the way I do it if i'm using a pencil and paper. 1)Find out what net volume you want (dimensions you can work in as well) 2)Find out how much port area you need 3)Knowing the net volume desired, find out how long the port has to be 4)Calculate the port displacement. In the case of a slot port: height x (width+.75) x (length-.75). Add .75 to the width for the port wall, subtract .75 from the length because the port goes through one of the sides 5)Port displacement + sub displacement (and any bracing) + net volume=gross volume 6) Draw up a box that has the gross volume desired. For instance, you want your box to be 12 cubes net. Say the port for that size enclosure will displace 1.5 cubes. Sub displacement is .5 So 12+1.5+.5=14 cubes. So you want to draw up a box that is 14 cubes gross. [/QUOTE]
