A .75 cubic foot is recommended for sealed enclosure and 1.75 cubic foot for vented enclosure. For vented enclosure, you would tune the box to 33Hz by putting in a 4" diameter port that is 10" long. As for the shape of the box, it is impossible to give these dimensions as we don't know where you will be putting it. So the shape must be decided by you. Here's a way to calculate the sides of an enclosure. One cubic foot is 1728 cubic inches. Let's say you want to build a 6.5 cubic foot box. Convert 6.5 cubic feet to cubic inches by multiplying 6.5 times 1728, which equals 11232 cubic inches. The area of a rectangle can be calculated by the formula Length x Width x Height = Area. So, pick two sides that you would like to come close to. Lets say a height of 22 inches and a depth of 20 inches. I'll pick 24 inches as the width to start. 20 x 22 x 24 = 10560 - too small 20 x 22 x 26 = 11440 - too large 20 x 22 x 25.5 = 11220 - CLOSE ENOUGH So, your internal dimensions would be 22" High, 20" Deep and 25.5" long.

As long as the box is .75 cubic foot size, it will work great.
