Chris, I wonder if this discussion from a while ago might relate usefully to your intended uses for LADSPA plugins in SoX...

http://sox.10957.n7.nabble.com/implementing-loudspeaker-crossovers-using-Sox-LADSPA-plugins-td5464.html

As for my own use, I did not pursue the discussed application further because of the problem of precisely synchronizing each individual stream.  I may at some point revisit the issues, but not for some months at least.
