I have searched and searched and surprisingly can't actually find anything on this. How much port would be the recommended as the minimum to avoid port noise and recommended for optimum performance? I don't really know a lot about these low cone area high power woofers. Lets say for example the box is 0.5 to 0.6cu.ft, and tuning between 30 to 35Hz, what are my options for port?

I usually stick to around 13-14 sq.in. of port per cu.ft. of box, but that leaves us with a very small port?

10-12 square inches TOTAL should be good. I know I have 12 in^3 for mine in a .56 cube box, and it works good. It is a long port though.

It depends also on the tuning. But say if you were to use a conventional 33-35Hz, you will want a minimum area of 21.5in^2 by my calculations. This is for the beginning/entrance of any type or port you use, or if reverse tapered, the opening/ending of the port.
