are you writing your own software to do this ?
mine still needs some minor fixes to handle this sort of setup.
how are the speakers connected to the channels ?
What I think would be possible as an experiment
though (without
involving a budget the size of the Pope or TU-Berlin), is to place a
large amount of uniform speakers in a circle and then feed them with the
same monophonic signal. If everything works as expected, it should then
appear like the sound emerges from the center of the circular array of
speakers.

Would that work?
It probably would, *if* you can get all speakers to be exactly in phase
over the entire frequency band. This will be difficult at HF, and having
part of the range not focused will destroy the effect and identify the
radios as the source of the sound.
You don't even need a full circle or sphere. I'm currently involved in
a project using an array of 228 speakers / 64 channels suspended as a 3m
diameter 'chandelier' from the ceiling. It will create sound sources moving
above and around the listener's head.
