The BLaH papers are available from http://www.ai.sri.com/ajh/ambisonics/ though currently there
seems to be problems streaming the actual papers from Scribd.

Thank you all for your insightful replies. I know I could spend years
trying to setup a scientifically accurate ambisonic setup. But
then I would probably never make any music!
Dave, are there a links to these papers by Eric, Richard and Aaron
that you speak of?

That might be the easiest thing to try first.
possibly. there is one thing on the homepage that strikes me as odd,
however:
"Ambi.decode~ decodes an ambisonic encoded sound field to a user-defined
speaker array of up to 16 channels (more can be added by using more than
one ambi.decode~ object). Messages control the speaker layout, global gain,
mono/spatialized balance, and decoding order weights."
i don't understand how one could just use two independent decoders and
still arrive at an optimum decoding result. it's not clear how the decoder
works, and i'm not sure it's really state-of-the-art... others may be able
to comment.
You'd certainly want to look at doing some manual optimisation with
multiple decoders, which might be as simple (and time consuming!) as just
tweaking things by ear or might involve a full scale optimisation using
something like Bruce Wiggins' heuristic approach.
check out the BLaH paper "is my decoder ambisonic?" for some of the
pitfalls and a list of known-good decoders.
But do be aware that the excellent work that has been done for these
papers by Eric, Richard and Aaron is (currently (that I'm aware of)) only
for first order decoders and domestic sized rigs.
Ideally I would like to have 8 (maybe more) speakers that I could
configure in various different ways.
for larger audiences than, say, 5-10 people, i would recommend a
third-order horizontal-only ring of eight if you are looking for proper
localisation. a cube in my experience is problematic for more than one
listener, unless all you want is envelopment.
Agreed.
