ARSkemp 10+ year member FI-AQ-PA-AB-Profile-MB-RD 659 0 Salas/Chico, CA Jan 19, 2009 #17 yeah i can do math no prob, and volume sure....not bout how to calculate the port tho for tuning and how it relates to the volume....is there a link? Click to expand... I used RE enclosure calculator to get a general idea, and then go from there and redo the calculations by hand (i've found that re enclosure isn't completely accurate) Everything is simple geometry calculations except for this: Fb = .159*sqrt((Av(1.84*10^8))/(Vb(1728)(Lv+.823*sqrt(Av)))) (i think i typed that out right) Fb = frequency Av = area of port (in^2) Lv = Length (in) Vb = box vol (ft^3)

Click to expand... yeah I'm a little confused by the equation, but I think I just need to look at it a lil more That would be much appreciated if you could send the excel document to me. If you want you can email at darinschafer@hotmail.com
