Just got mine today, and when playing music/youtube e.t.c on just half of the max sound, the whole device is shaking so much it uncomfortable to hold, really a downer.
Have you tried setting the Equalizer to Flat? Or Any setting that reduces Bass. The iMac delivers so much bass, it would shake as well, if it wasn't soo damn heavy.

Played with 3 Airs at the Mall and all three had the sound cranked up to Max, and it was not loud as I would have liked them, and no shaking at all. Wish Apple would place the speakers facing the user next time but doubt it.
