[QUOTE="Bill T., post: 398777, member: 552106"] Actually, bcae1.com doesnt explain the tuning frequency in relation to the port length and surface area. And the calculator they do have to calculate tuning freq doesnt work right. It always gives lengths under 5"... unless its user error. If you could find that equation, that would be great. I have a few plans for my next box, including a SS box. smullen - port area is always measured in square/inches and its almost always at the exit point (correct me if Im wrong) Bill T. [/QUOTE]
