I realized that my jbl-speakers I use additionally to my alesis are a little
light on the lower end. So I (mis-)used ambdec's crossover to give me one
matrix with the 100Hz and above for the whole setup and one matrix for below
100Hz that just contains and feeds the main alesis speakers. Works pretty well
as far as I am concerned...
Of course, each speakers signal is also feed through jconvolver with a drc-ir
to make it sound superb (as opposed to just the plain good sound of the
speakers).

I think that full-range in the sense of ambisonics just means (a) that its
more then the little rear--satellites you find in 5.1/7.1 and (b) that every
speaker is supposed to get (and reproduce) the whole spectrum according to its
abilities.

Have fun,

Arnold
