Height x length x width divided by 1728 minus wood thickness and divided by number of subs

You also need to account for sub and port displacement.

If i had time id check but as the above poster said lxwxh, just make sure to subtract wood thickness (on both sides) before multiplying and dividing.

Edit:Just checked and they give you the inside dimensions, so go multiply the inside dimensions given without the port and divide by 1728.

Then Google around and find out what your sub displaces. What kind do you have?
