Hello buck, i have a question that i cant seem to get answered. Recently built a box for a 12" shocker sig, 2.9 cubes with a slot port coming out the side using the rear wall.I used the 12volt calculator and ended up with 38.5 Hz, which is what i wanted. right around 3.125x15x 24.5 long
Guy i know has a meter and testing the new box he discovered that it was tuned to or peaked at 35Hz. he said that the port on the rear wall of the box was making the length seem longer.
maybe i cant get an answer cause the way im wording it
Thanks for any help or even trying to figure out wtf im asking.
