Now I would like to construct a higher-order sound system, ideally with
consumer-level (and consumer-priced) components. I don't need a big
dynamic range, high power, or the best sound fidelity possible, I just
need a working prototype. This is the part I have found very little
information on in my research�
My understanding is that 8 channels is the minimum needed for stable 3-D
Ambisonics (rather than planar surround).
There was a recent reminder, on this list, within the last month, that
one could use 6 channels (the mid points of the faces of a cube).
I've never heard anyone say they've done it, let alone say it was 'nice'.
(The engineering would, also, not be fun ... though you are not obliged
to place speakers mid-wall/ceiling/floor ... you can tilt the cube!)
So I'd stick to eight unless you are really adventurous.
We've used it in the dim and distant past and it's not to be recommended as it is right at the
limits of usability (very unstable image, incredibly tiny sweet spot and so on). I would compromise
on the quality of the speakers so that I could buy eight, rather than buy only six better ones
(ditto for the audio interface and amps)
