Case B : Use a steady state 50 Hz signal and slowly pan it to new

Of course, as this involves the level from each speaker changing, the
speaker feeds will still have the higher frequency components. Indeed, I
presume they would appear even if you physically moved the speaker.
Panning an LF signal around at F revolutions per second in a 3rd
order AMB system would mean that the speaker signals have sidebands
at +/-1F, +/-2F, and +/-3F Hz. But no more.
Almost all of that would cancel at the listening position, where
you'd have a constant amplitude pressure and gradient.
Ciao,
The idea of listening for pleasure to bass sounds without overtones or
transients conjures up an image of a twitcher tracking down a rare,
three legged sparrow. The public just don't understand..
