If I build a slot port on one end of my enclosure, do the inner walls of the port need to be 3/4" material?
I asked, because when I run the calculations on a slot port with the same area as a 7.5" tube (8" O.D.), assuming 3/4" material for the inside walls of the slot port, the slot port reduces the internal volume of the enclosure enough that it looks like I am better off using the round port. Defeats the purpose of a "shorter" slot port when the enclosure volume is reduced making the port length longer. . . . If I could use 1/4" material on the inner slot port walls, it looks GREAT!!!
Is the pressure about the same on each side of the wall of a port? I know with a round tube the pressure is less of an issue, but what about a square port?
Thanks,
