Port area for a square/rectangular port = W x H

Port area for a circular port = Pi*r^2

For port area, you basically just take the L x W x H of the entire port that's in the enclosure. This includes the walls that make up the port.

and divide by 1728 right? 14.5x2x26.5/1728 = .44 ????

Yep, but I believe squeak was saying to count the port wood. So if your port is 2" wide it would be 14.5*2.75(assuming its 3/4" wood)*26.5. If it is only 1.25" wide the first formula would be correct.
