Yes I am running Bi amp with my piezos. I have two melded arrays and two straight arrays. There are no passive components, except for a series resistor on each array. The four pole speakon connector is not wired funny except that i have paralleled a second connector so i can stack the cabs.
My main reason for Bi amping is so i can have more control over the high freq section. I just can't stand it when any system is too bright and EQ is not always the answer. Sure I could of added an LPAD, but I like the fact that I am tri amping my system. I think it gives me a lot of options to tweak the system and make it sound as good as i can.
As a side note I am using two Peavey CEX L4a's for active crossovers.
