Well basicly, the deeper the port length the lower the freq. And in order to know what freq. your box is at youll need a mic.

Did you make the port to RF specifications or did you use a program to redesign for a larger port tuned to the same port frequency?

If you want to know or at least get an idea of what you tuned the port to, click on the link below, there's a port calculator at this site that should help.
