[QUOTE="Jeffdachef, post: 8355010, member: 650438"] You subtract 1.5 from each due to thickness of 3/4 mdf. Then you multiply. Got an easy box for you 23.5 height X 44 width and 33 depth. Two 10 inch sonotubes at 15 inch length will give you 33hz tuning, plenty of port area for a round port. 15 cubic feet net after sub and port displacement. Assuming you will brace the box with a lot of bracing. Its 15.25 cubes without bracing. [/QUOTE]
