take note:The following table gives an approximate volume in cubic feet you need to plan your enclosure for based on the woofer size. The woofer is the single most important element in calculating your enclosure as it makes 80% of the air or more.

Woofer Size Enclosure Volume
4" .25 - .39 cubic feet
6" .35 - .54 cubic feet
8" .54 - .96 cubic feet
10" .96 - 1.8 cubic feet
12" 1.8 - 3.5 cubic feet
15" 3.5 - 8 cubic feet

How you distribute that volume is pretty much up to your needs, just don't make them square! Square enclosures will make awful bouncing frequencies. You might have noticed that many sound reinforcement speakers have the sides of the box tapered in toward the back, if you can do that, do it. that helps sound move out and not bounce like it does between parallel surfaces.

FORMULA >>
To figure your enclosure size in inches, multiply all the sides as follows height x width x depth, so if your box is 16" x 12" x 8", you have 1536 cubic inches. Take that figure and divide it by 12 three times, so 1536/12/12/12=.89, so, your enclosure is .89 cubic feet.
