I have Q-Form type 2 I got online . came with no directions. I am using a Infinity Kappa Perfect 10.1 DVQ with the removable pole piece for the Q adjustment.

I am not sure what I should cut the length of the port to be.

1 cuft. box , 3 inch port diameter .

I can give the sub specs if needed

I would make the port around 14 inches which will give you a tuning of around 34hz. Check out the below site, you can use the calculators to figure things out.
