It depends.

How much port area is recommended?

The smaller the area, the shorter the length of the port will be. And obviously, the bigger the area, the longer the port will be.

Typically, you get less port noise with a bigger area, but there shouldn't be a major difference if built right.

3" port is more likely to have port noise than a 4" so it really needs more of a flare. Also more port area allows you to use more power //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

It really helps to know what subs the ports would be coupled with.

 

If it was an 8 or 10" sub, then doing it 3" will probally be just fine. Anything bigger could create noises and big group delays in box performance.
