I've put this up on other forums, thought I'd share it here as well. This calculator can do some neat stuff, it's by no means perfect nor perfectly laid out, but the calculations are certainly accurate. It runs in Microsoft Excel and OpenOffice's CALC program which is free if you don't have MS Office. I've built the box in my van, along with six others for other folks locally by it with no issues at all and the box tuning was right on the money each time. The handiest feature IMHO is that you only need to enter two of your known dimensions and it will calculate everything out for your entered box volume, tuning and port dimensions to give you the third dimension. It also has handy cut sheets available as well so you know what each panel needs cut to for building the enclosure. Here's the LINK. Enjoy it.

Note, I'm working on a much revised, easier to use version but it's taking quite a bit of time.

 

Quick update, have a little newer version of the calculator available that I forgot I had uploaded in both Excel and OpenOffice formats.

Microsoft Excel format

OpenOffice format

 

Several of you have downloaded it, any questions or comments?

 

Nothing? Not even a "How the hell does this work?"?????

 

Alton, thats awesome. thanks for the calculator. it takes some getting used to but isn't super hard to use

 

Well I tried to install open office but either it didn't install correctly or I'm just retarded and couldn't figure out how to open it correctly (probably the latter) but I couldn't figure it out.

 

Glad I could help there topper.

What is the message it's giving you Thogert?

 

It's not a message, the shortcut it made just opened up a folder with some file folders, a jZip archive file, a windows installer (which opens up the same install thing I did in the first place), a setup application, and a configuration sett...

 

hmm.... that's odd.... you downloaded openoffice from OpenOffice.org? I don't know if it's the right program if it didn't come from that site.

Here's the link for the download site if you want to try it again.

 

Ok, sorry it took me so long to get back to you.

I re-reinstalled it and it works now.
I am impressed on the ammount of work it probably took to create that calculator. It is very handy indeed.
One question though, is the round enclosure part not finished or what?
