Mort, I think you are wasting your time asking for a response of any value. You will just get the same old meaningless words typed onto the page.
I forwarded AndyG's measurements to my brother who owns the ADM 9.1's and he was a bit disappointed but not really surprised as about 8 years ago we owned a Mackie FR1400 PA amp which was rated at 250w RMS into 8ohms and was a hefty old thing. The ADM's barely weigh anymore than most good quality passive speakers of the same size (if at all) and they are claiming a total of 325w per channel so he didn't really believe there could be the same kind of amplification inside them as the Mackie had. Now we know and I am really pleased that someone finally made proper measurements as I really was baffled as to how they could be so much more powerful than all the competition but always worried about those very brief specs on the AVI website.
I guess their designer either used software to calculated the max power or just ran a number of individual tests to get some big numbers and then combined them all to get a massive 'car hi-fi' type output figure!!! Andy's tests clearly show this is not anywhere close to realistic in the real world.
