Re: taking consideration for mdf width in box volume calc
To convert from cubic inches to cubic feet.

Most people prefer to see the box volume in cubic feet.
If it is a single sub enclosure (no divider), then subtract 1.5" from every dimension (assuming your using 3/4" mdf). So you would get [(H-1.5")*(W-1.5")*(D-1.5")]/1728

Wedge boxes are tricky to get the volume of . First you get the internal volume of the box not including the wedges. This volume is [(H-1.5")*(W-1.5")*(TopD)]/1728.
Then find the volume of the wedge (right triangle) parts of the box. The internal volume of a wedge is 0.5*(W-0.75")*(H-1.5")*(wedgeD-1.5")/1728 (again assuming 0.75" mdf).
