Anyone know modeling software that has the Ethos included?
There won't be any software with the Ethos already in the database. You'll have to manually enter it into any program you use. Here's a guide on winISD, and in the first post it describes how to enter driver parameters. It's important to enter them in a specific order and let the program auto-calculate some of the other parameters or you'll get an error (this happens when the auto calculations don't match your manual input).

For subwoofer enclosures, there's only a few parameters that are really important: fs, vas, qts, and sd (surface area). The rest are optional for the most part.
