Box dimension help

[ja81]

First time box builder here. I'm building a ported box for an AQ SD8. I want the box volume around 1.0 cuft and tuned to around 40 Hz. The measurements I came up with are:

Internal measurements: 11H x 14W x 12D

External measurements: 12.5H x 15.5W x 13.5D

Slot port measurements: 11H x 1.5W x 16D (10.5 + 4.75D for L port)

Do these dimensions seem correct?
