Got a ported box for free, can someone tell me how its tuned?

[DarrenE46 10+ year member]

Neighbor gave me what looks like a prefab box. Condition and quality were decent so I accepted. He didn't know what it was tuned to, I tried figuring it on my own but didn't really get any where. BTW: It is a wedge shaped box.

L: 39"

W: (front slope) 13.25"

H: 12.75"

D1 (top): 4"

D2 (bottom): 7.75"

Wood thickness: .5"

Rectangle Port Measurements:

L: 26.5"

W: 11"

H: 1.5"

Thanks for your help!

It is about 0.8 cubes with port displacement accounted for tuned to around 42hz.

What say you? One person says 37hz, another says 42hz. Any other opinions? What would the characteristics of this box be?

its gunna be pretty high. With such a small box you would need ridiculous port area to get low

Any more guesses? One says 37, one says 42, and another just says pretty high. I appreciate all the help so far!
