. . . From 25hz and up things are only going to favor the XS30, same goes for anything below 15hz.
This is pretty much exactly what Tom V. told me when I was trying to decide between the XV15 and the XS30. I went with the XS30 for the extra output below 15hz, and also because I'd never had a sealed sub before and wanted to try it.
