If i have a box already made and know all deminsions such as this:
Volume: 1.75 cu. ft.
Depth: 19"
Height: 13 1/2"
Width: 17 1/2"
Port Height: 12"
Port Width: 1 1/2"
Port Length: 25"

how do you calculate the tuning frequency? what is this box tuned to?

I get it tuned to ~33 Hz. That was by throwing some numbers into BBP6.

My volume came to be about 1.65 ft^3. I assumed those were external dimensions.

I got 31.17hz with exact dimensions given
