[QUOTE="squeak9798, post: 1302697, member: 555320"] Port length Lv = Av*1.84*10^8/[Vb*1728*(Fb/0.159)^2] - 0.823*sqrt(Av) Av is the cross-sectional area of the port (in square inches), Lv is the length of the port (in inches) and Vb is the enlcosure's net volume (in cubic inches). Square area of a circle = Pi*r^2 Square area of a rectangle = H * W Guess the rest depends on what you mean by "junk like that". [/QUOTE]
