I've been around for awhile, and I have a simple question. When you figure the length of the port, using the math formula, do you use the net internal volume of the box before the sub displacements etc. I'm asking because one of my friends always gets the volume of the box and puts that # in the formula to figure the port length. All of his boxes have sounded normal, and have great low end. He had two brahma mk I's and they pounded out the lows, so I was just curious if the tuning was correct in doing it this way.
