Ask pro-rabbit or ram designs on here. Both good box builders and they could figure that out for you.

Do you want the easy way or the other easy way?

The easy way would be to measure the interior dimensions to find the volume of the enclosure. Plug that into a box design software. Then, measure the dimensions of the port. Set your port area. Change your tuning until you get the length of your port.

The other easy way takes a little math. Solve for frequency and plug your variables.

Fh = Resonant Frequency

Lowercase Nu = Speed of Sound

A = port area

Vo = Static volume

L = port length
