Verify my box please

[TommyK]

Im building a box for a 12" sub. I used RE box calculator and came up with this:

Box width: 20"

Box Height 14"

Box depth: 12.5"

Bottom depth: 12.5"

Wood thickness: .75

Square port height: 12.5"

Square port width: 1.1"

Square port length 1: 10.65"

Square port length 2: 8"

Total port length: 21.05"

Its telling me the box will be at about 1.29 cubic feet and be tuned to about 34.41 Hz. Now ive heard people say that the Re box calculator can be wrong sometimes. Given these dimensions what will my box actually be at?

That's pretty close I'm coming up with about 33.9hz. But that port is too small, not for the size of the enclosure but port ratio. I would do 2x8 so that you wont have any port noise. But you should already know all this

Thank you! I was thinking about how the port might make port noise, but I figured it wont be heard because they port will be facing back in the trunk am I wrong? And I dont understand what you mean when you say the port ratio is too small, Im rather a noob.
