You are pretty much completely right. The loudness setting is designed for
low volume levels but most people (like me) just keep it on the whole time
simply because it sounds better.
However, perhaps some speakers are not as sensitive to low/high
frequencies at low volume levels as well. So at low volumes the ear hears
even less low and high frequencies. (This is just a wild guess in my part,
I'm sure there are some people with some real knowledge on this list who
can give some input.)
