And how would that distant denser array (of virtual speakers) be
created ? By WFS ? That assumes that the WFS system actually works
(as WFS) at the frequency of interest. But the starting point is
that it doesn't. This is again trying to pull yourself up by your
bootstraps.

I'm pretty sure that S.E. does some clever things above the aliasing
frequency. I'm also pretty sure they can produce convincing distance
cues (for some material, probably carefully chosen for the demos).
But I don't believe that any of that is actually WFS.

There were some experiments (in the early 1950s IIRC) using just
three speakers on stage, playing a recording of an orchestra
*made on the same stage*. I'm too young to have been there, but
from what I've read it seems the reproduction was near to perfect.
That doesn't mean that three speakers on stage can do reproduce
whatever you want with the same result.
