View Full Version : help confirming L ported box specs

Is there a program or website I can input the internal dimensions and port lengths of my box to confirm tuning and volume?

and how do you measure the L port length?

I'm not aware of any software that backward calculates tuning but it's pretty easy to do. Just get your internal volume and port length and then start plugging tuning frequencies into a port calculator. When you find a tuning frequency that calls for a port the same length as yours, there you are.

And port length is measured through the center of the port, regardless of how the port is shaped.
