#1 The specs mention Bi-Wire Capabilities. Can the speakers be setup in a Bi-Amp configuration? I have read about Bi-Wiring and it looks does not really make any audible difference, nor any additional control apart from maybe varying the ohms to the amp.
Bi-wiring allows two benefits. You can separate the load of mids and highs to one amplifier and lows to another. Or you can increase the output from a single amplifier by increasing the load by reducing the resistance (ohms). For example, bi-wiring a pair of 8 ohm speakers to a single amp will be as if you are running four 8 ohm speakers from that amp, making the resistance on the amp down to 4 ohms. Most amps provide about 50% more power when this is done, but it is more load (work) on the amp.
