Since I'm not a physicist, I consider this a semantics difference. What I meant by amplify is some device that increases volume of sound. I can do the same thing with my voice. Same energy on the vocal chords, but properly placed in the resonance, the volume and projection are increased. (which would mean a lower energy requirement to produce the same volume?) Jeff
