If you watch carefully on the Hawaii videos you see them testing each amp one by one by connecting and disconnecting them while the tone is running. What you hear is the drivers associated with that amp broadcasting the tone when that particular amp is connected. Which verifies also what's being said in this thread about how dual tone works on Federal controllers.
Any idea why you can year the normal tone slightly in the background of this video?

If I'm not mistaken that's the transformers in the amps.

Ah, so the frequency of the tone is flowing through the transformers which makes the transformer hum at that tone instead of the normal 60hz? Wow that's pretty neat!

yeah. same can be seen for normal transformers which "hum" at 60 hz. if i put a magnet near my fire lite ms-2's power transformer it vibrates!
and yeah, if the same tone was broadcast out of the drivers it would make them heat up as if the sound reaching them is out of sync with the sound they are producing, that will technically make them work twice as hard.
