Enclosure Volume Calculators

**Sonnie** · **11-22-08, 02:40 AM**

Thanks to avaserfi and NEO Dan, we have created several enclosure volume calculators for your use in helping you build your subwoofer enclosures. Accurate calculation of enclosure volume is essential in designing a properly functioning subwoofer. These calculators will calculate the volume for square, rectangular, triangular, trapezoidal and cylinder tube subwoofer enclosures, sealed or ported, including driver volume, bracing volume and port volume displacement. I have always found these handy and used them at various other sites... I am glad we have our very own now, customized for us.

We will happy to entertain improvements... please let us know what we can do. Within reason, we will certainly try.

Thanks for the tool. This is very useful.

this is great! I could have used the brace calculator in my last build lol

Sonnie, is there a link missing leading to a port tuning calculator?
(given enclosure volume, given port diameter and length - solve for tuning frequency?)

I have asked about this previously... as to why we do not have it. I can't remember now what I was told, but I see no reason we cannot fix one up. I know it can be calculated in WinISD, but we should able to provide a simple calculator for convenience sake.

They look great, but how about metric data input also? Most of the world uses SI units.

We got Liters in there...

I do not have a problem offering a full metric page if we can find someone to develop it for us.

You still have to input data in inches; litres are only a result.

But we still got it...

I'm not great at Javascript, but am prepared to donate my Visual basic routines to convert from metric to imperial and back again (as used in boxnotes) if they would be of any help

I will be happy to add any code to the page that will help... but that is about the extent of what I can do.

I guess we would have the first and only calculator that does metric, since all of the others I have seen do not include it.
