Ok. Box is 14 cubes, 8 x 20 port tuned to 28 hz. What port length do you get?

Trying to compare different programs for port length. I've gotten many different answers.

~28.75", winISD Pro and carstereo.com calcs agree.

Alright. I'm getting 28.27 with winisd. Bassbox pro gives me 31.13.

Even if you did do it that long, it would only drop the tuning to 27hz according to the other calcs.
