Know the T/S specs of your woofer? Download WinISD and plug 'em in. On the "box" tab, you can hold down the mouse button and move up-down, left-right, and see the results change visually, on the graph. It'll also give you box and port dimensions. A cube, roughly 20" per side would be about 4.5 ft3.
