OK lets say im using a scrap piece of 3/4" MDF that is 10" H and 2" W so it would be 10 x .75 x 2 = 15 cubic inches. Is That right?

You did the calculation right by adding all three dimensions

Take that cubic inches and convert it into cubic feet, assuming you used cubic feet for your enclosure.

15/1728 = 0.008680555555555555555555555555555555555555555555 56

50 decimal places for extra precision.

The reason you use 1728 is because there are 1728 cubic inches in one cubic foot

12^3=1728 btw if you didn't know.

Sorry to jack your thread, but it loos like you question was answered. So... How much area should you leave open for air to pass through? Is it the equvilent to the cone surface area?
