So I got a crappy beat up box from a friend of a friend that I was going to scrap for parts. The rest of the stuff that was going to be used ended up being broken. The only thing that is going to be used is the four aero ports from the box. Now I'm having problems figuring out how to get the tuning right. The new box is going to be about 3 cubic ft. The ports are 4.25 inches in length, and 2.375 inches in diameter. I figured out that with one port that I would b tuned to 31htz.  Now I want to be at about 33 or 34. So I was wondering if it changes the tuning if I add more of the ports. Thanks for the help in advance. I'll post some pictures of the ports when I can</p></blockquote><p></p>
