Im looking for box desiging software or help from someone here (1 Viewer)

[Jason Garver]

I am looking to build a 11 cubic ft sonotube tuned to 16hz. I will be using an Ascendant Audio Atlas 15". I have no idea how to figure out the port size to get a tuning of 16hz. Also it has been a while since since I've had a math class so I forget the formula for determining the volume of a cylinder.

Any help that you can offer would be greatly appreciated. Thanks - Jason

I'm looking to do the same.

Here is a great sonosub link. http://www.quux.net/roo/diy/sonosub/

I used it to come up with the following tube sizes.

22" X 50" = 311.462 Liters
24" X 42" = 311.359 Liters
26" X 35.75" = 311.037 Liters

11 cubic feet = 311.52

I'm too stupid to figure out how to put the correct info for this driver into WinIsd.

I had a tube designed for a Shiva using their software, but I would much rather build the Atlas.

WinISD isn't all that great, you're better off using the Pro version .

Better still is Unibox ,which requires Excel 2000.
