Bi-wire: is it worth it?

There is an interaction between speakers by "Back EMF" generated voltage. Bi-wiring separates speakers by inductive reactance of the wires' and amp's output impedance divider. It works for some speakers more than for the others. I think it depends on xover design.

Nick_sr, I don't know - inductance is inductance in any configuration but there are different and often strange findings. I've heard, for instance, that shorting positive (red) of upper and lower speaker in biwired speaker changes the sound. I have tried it and it does, but the only explanation I can come up with is that it removes half of the inductance from divider. Change was very small and I don't remember if it was for the better or the worse. It must've been for the worse since I rejected idea.
