Need a good online subwoofer calculator

[white trash wagon]

NE1 know of a good online subwoofer box volume calculator? Hopefully one with sealed & ported systems. I found a few, but they don't have options for total system Q or optional tuning frequencies

I used to have all of those formulas back when I was building a lot of ported enclosures. I found them on the web. Maybe try google?!

Yeh, I looked at that one, it really just explains the different enclosure types & simple math of measuring box volumes.
