I goofed on the first port volume. It should be .049ft^3. So if I made a port that was 10"x2"x4.25" it would give me a port volume of .0492ft^3, which is pretty damn close to the recommended.

So then it would be the woofer displacement (0.092ft^3) + the port volume (0.0492ft^3) + the port wall (.0015ft^3)

So if I aimed for a box that was 1.1427ft^3 I would end up with 1ft^3 after everything has been taken into account? And I would have the recommended port specs (even though its now a slot, same volume though)
