The volumes I got from Kicker Technical and they already take the volume displacement of the drivers & ports out of the equation. So, I just need simple volumes from these chambers. But thanks for a great question.
Now, can anyone solve this? The hardest part is in the corners. Where it makes an angle (I think a 49 degree) then goes 11 inches, then angles again (41 degree I believe) so it equals out to 90 degrees. But during that 11 inches, the other two sides of the invisible 'triangle' it makes inside the box must be 8 1/4 & 7 1/4. But will the thickness of the wood take any of this away?
once we divide the internals up into triangles and cubes, then it becomes easier to reach a final volume.
if I am correct in thinking the inside of the 'triangles' will be 8 1/4 & 7 1/4 then this is how I'd come to the final volume:
A right triangle is merely half of a cube, but since we have two of them, no need to divide by two.
8.25 x 7.25 x 12.25 (height) = 732.703125 (triangle parts volume)
3.75 x 35 x 12.25 = 1607.8125 (rectangular cube underneath triangles)
8.25 x 20.5 x 12.25 = 2071.78125 (rectangular cube between triangles)
1.5 x 8.75 x 20.5 = 269.0625 (add-on box in the front)
total = 4681.359375 (cubic inches)/ 1728 = 2.70912 cubic feet
the sealed chambers are the easiest and are also identical.
17.125 x 10.75 x 12.25 = 2255.1484375 / 1728 = 1.305
If I did this right, and used the right numbers (you should be able to check the angles and make sure I did it right) then my box would be green lighted for building.
Thanks for all your help in advance!
