I am building a couple of transmission line subs. They are based on Nelson Pass' El-Pipe-O. Does anyone know how to calculate the effect of a specific amount of stuffing per cubic foot on the volume.
If I have 6 foot long 12" dia. tubes, how much stuffing per cubic foot will increase the effective length by 6 inches. This is just an example. I'm hoping there is some kind of formula.
