    Hey all! As I posted before, I'm building a coffee table sub. To do that, I'm modifying the Adire design and trying to come up with dimensions that add up to 142l.

    To that end, I wrote an Excel spreadsheet that takes everything into account. Internal bracing, holes in the bracing, etc etc. This allows you to just play with the numbers until you get a volume you like. It's not very complicated, but it's saving me a TON of time, and I thought I'd share with everyone here.

    I can't post it on my server, but I'd be happy to email anyone a copy. Shoot me an email at [email protected] if you're interested.

    Thanks Joe, I'm sure it'll save others some valuable time also. BTW, I've always used 3.1417 for Pi. Have I been wrong all these years?[​IMG]

    Maybe just a little [​IMG] From a math text:

    "The value of pi correct to seven decimal places is: 3.1415926."

    if you type =pi() into excel it will give you the value out to some decimel place.... just a handy dandy tip from a spreadsheet nerd!

    Sweet, did not know that. I'm far from an Excel expert...If there's interest in it, I'll build a Windows program to do this - that's my real strength.

    Just thought I'd share my project with you folks. This is the reference design for the Adire Shiva. 85l vented design, Adire alignment. It was originally 19x19x20. I squished it using my spreadsheet, and now the box is about 76l, because I'm going to stuff it.
