bass lover Posted October 24, 2008 Report Posted October 24, 2008 Ok I need to know the eqaution to find out how long to make a port. I've always used it on ROE but the site won't work for me right now. And I need to know it right now. I'm building the box tomarrow and need to have it designed by the end of the night.
