tetrahedral setup for the subs (for example: front left floor, front
right ceiling, rear left ceiling, rear right floor). this setup is known
to be unstable for full-range use, but could work great for bass,
depending on how far your subs have to reach up. then again, i'm not
sure if the rigging hassle is worth the z information in the bass.

hmm, i think i would rely on the internal electronics of the tops for
the HPF and feed them a full-range signal of all components, and then
maybe measure one and design a suitable roll-off for the bass
speakers... but i have never had the luxury to do that, i always set the
LPF by ear.

sending high-passed WXYZ and full-range higher orders to the tops won't
work well, i guess. if you want to take care of the band-splitting in
your mixer, your best bet would be ganged high/low-pass filters for all
the orders. if you have the time, gear, and expendable ph.d. student
labor at hand, it would be fun to try three- or four-way systems with an
increasing number of speakers as the frequency goes up.
but since the most expensive part for massive ambi systems is the
amping, that's probably an economic dead-end, at least for now.

best,

jörn
