Ok. After some searching I'm settling on .75 cu ft @ 33 hz. But I've run into a snag. I know this shouldn't bother me, but it does. What part of an L-shaped box adds to the net volume? I can't for the life of me get my pen and paper work to match with torres box calculator or RE audio's.
This is my example box, not for the SA-8's just for example. The red is the port, blue is the internal volume. I've calculated the blue area to be 1521.75 cubic inches or .88 cubic feet. But the Torres calculator says it's .93 cubic feet. Am I doing something wrong?
