Hey guys (and girls) I'm new here and I've looked for my answer by searching, etc. but there is so much information within all of the forums, I can't find exactly what I'm looking for. I was really into car audio a few years back, but until recently, I've been chasing the speed bug.
My question is: When you're building a box, do you count the port area as internal volume? Which of these boxes are correct? Thanks in advance!
Target internal volume: 2.43 Cubic Feet
Speaker Displacement: 0.48 Cubic Feet
Port Displacement (19" x 5"): 0.215 Cubic Feet
2.43 + .48 = 2.73 Cubic Feet
2.43 + .48 + .215 = 2.945 Cubic Feet
