Allright guys, I see a lot of worthless programs floating around and I want to build a new - very general - program to figure out some attributes of a common enclosure. I need to know all of the equations that are needed, Jmac, please help me out here as it would save a lot of time for you and others if I could get this working. I'm going to have a lot of time over thanksgiving break hopefully and we'll see what I can do.

Please, just post all the equations and what they calculate....if you're not 100% sure though, please do not post, this is going to be an accurate program I hope....I just pray I figure all the programming out behind it, the math will not be a problem.

What are you going to code the program in?

Av=port area(in^2)
Bv=box volume(ft^3)
F=frequency
(Av*1.84*10^8/Bv*1728(F/.159)^2)-.823*sqrt Av=port length
