Re: help me tune again
Wow. I'm glad you found this. Since loudspeakers101.com went down I was looking for it. This calculator is accurate...a lot better than WinISD. I have done calculations that have the same outcome as this one. The only thing you need to remember when using it is that you need to do it twice. Once using the internal box volume (- sub displacement) and when you get your port length, find the port displacement, subtract that from your box volume number that you used the first time, and then do it again using the new box volume to find you final port length. It also accounts for port correction as well.

Lv = [(14630000 x R^2) / (Fb^2 x Vb)] - 1.463R
*Vb = vol. in cu"
**R = sq.rt. A / Pi (for square/slot port)
