Probably right in the vacuum of science; in the field, that's the biggest load of crap I've heard in a while.
Here's the proof.
1) go to a concert
2) note the size of the PA speakers
3) laugh at the statement you made
OR, just listen for yourself. That's all I would encourage anyone to do; don't take my word for it and definitely don't put much stock in scientific theory. It's all about what it SOUNDS like, not what's popular, looks good or is endorsed by me or whomever.

Music is not science. Hearing is not science. Leave the mathematics alone, if it sounds great, it sounds great.
