Fill the enclosure with styrofoam popcorn(peanuts). Then empty it into a cardboard box. Measure the width, height, and depth of the popcorn in that cardboard box. Then multiply those three measurements and divide the number by 1728.
Example: C-box is 12"x10" inside. It fills up about 9 inches deep.
12 x 10 x 9 = 1080
1080 / 1728 = .625 cu ft.
1728 represents 1 CUBIC foot (12" x 12" x 12")
Your subwoofer takes up maybe around .06 cu ft, so you would have a net of .565. This would be too small for smooth bass with good low end extension.
You want to be around .75-.85 optimally before accounting for the woofer.
