Personal Amplification System

http://www.bose.com/musicians

Not directly related to tuning perhaps, but of real
interest to anyone playing amplified music.

These things are going to *change the world*. Yes,
they're really that good (we're testing them here at
work). Seeing a loudspeaker system that can be
carried by two people and set up in 2 minutes fill
a large parking lot with sound of uniform loudness
is something else!

Folks like me might actually be able to go to a rock
concert and enjoy it.

This paper explains it well...
