Hey guys, I am going to be extending a port on my box that is tuned to 41.5hz, to 31.5 hz. The length is currently 18 inches and I need to get it to ~35.85 inches. For this, I am going to have to bend my port multiple times to fit in my trunk. This means I need to know about how bending affects a port, AND the math behind the relationship between port width, height, length, and hertz. I can't rely on a solid length and then change the port opening size to get a certain hz, becuase I need a different length!
So, if anyone has any information on this, especially the math formula, I was would pleased to hear from you.
