dave31132 0 Posted March 19, 2009 I'm trying to figure out the port diameter and length for a box I'm going to build, but every time I use a formula from the internet I get something that doesn't seem reasonable. The box is for a Fi SSD 15. I figured the dimensions are 25x15.5x17 which is 3.81 ft cubed. I'd like the port tuned to 33hz. If anyone could help me out it would be greatly appreciated. And if you could leave the formula for future reference that would also be appreciated....thanks 0 Share this post Link to post Share on other sites
