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?
