I thought that might be it. Most audio work is music, or voice. Both of
which don't have any real infrasound content. So, as a result infrasound
is considered something to eliminate. However, in natural settings
infrasound is part of the ambiance. Eliminating or ignoring it is part
of what keeps our recordings from sounding as natural as they could. Or
that's my theory.
I have a book around here somewhere I read a while back. On the history
of sound. Really the history of sound reproduction. It gets into the
business of how our sound production and recording technology growth has
determined how we record. If the technology had of come in a different
order, we might have quite different ideas as to what's a good recording...

I was afraid of that. That's also my criticism of subwoofers in general.

I might play with one, see if I can get anything useful. IF it's cheap
enough.
