Truly, I was waiting for this!

OK, AR did do this. On more than a very few occasions. Typically they
used a string quartet playing music typical of the species.
*Relatively* limited and of similar timbre, but not of frequency.

And a few more things:

a) They practiced the transitions very carefully to make them as
perceptibly seamless as possible.
b) They carefully chose the transitional passages to favor the
midrange of the speakers so that subsequent highs and lows would be of-
a-piece vs. in-the-middle-of.
c) They kept it to fairly small venues of very conventional design
with a very small central and surrounded stage. This favored the
directional nature of cone speakers.

And, with all that in mind, they most certainly did fool their
audiences to well within the margin of error for randomness. Further,
they did it with their standard available-for-sale-just-like-this
speaker line, and very late in the game even used their own AR
amplifier for the test. By todays standards a pretty crude beast -
although I like them very much and keep several of them (and their
receivers).

But, in a typical residential situation, even in a dedicated listening
room, the sort of artificial environment created by AR for their tests
simply does not happen. And it is *EXTREMELY* unlikely that if AR had
chosen even a very small chamber orchestra with say... a harpsichord
or kettle drums or similar that they would have brought it off as
well.

Now, I would posit that with my back turned and no context, based on
many sorts of signal, my Maggies might fool me into believing
something "live" was back there under some conditions. The ringing
phone, a cat meow or dog bark  (we have both), even a door opening or
closing - sounds without context. That is a good start anyway.
