Here's a doozie for some of ya'll...maybe I can get a straight answer from one of the knowledge gurus here.

I was thinking a while back about building a slot ported enclosure for my BM when I first got it. Problem is, in an Ext Cab truck, there are very few straight, square edges to use as 2-3 sides to the port. Which got me to thinking, is a port on a ported enclosure tied directly to length and surface area or volume total? Such as if the external opening were 9"x4" (36 square inches) and the internal opening was 7"x5 5/32" (36.09 square inches), port length would be calculated the same as if it were, say, a tube with a surface area of 36 square inches? Or would it be figured differently?

I ask because it still kinda bugs me. I'm not losing sleep over it but it still makes me wonder if I could've done a slot port instead of a tube port.
