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?

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)

I also put the equation above into excel and made a port length and port frequency calc from it.

I can upload it somewhere if you want...

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
