Let me make it simple. Biwiring is nonsense. It is exactly as effective as the gauge of the combined cables. Nothing more. Biwiring sends the exact same signal down both sets of cables. Any field effects are equal in both cables. Single wired speakers split there feed to the crossovers at the rear speaker connector. Biwiring does it at the amplifier. All filtering of the input is done at the crossover.
If you want to make a genuine difference, pull the passive crossovers out, use line level electronic crossovers and biamp.
How does bi-wiring work?
To start, I do bi-wire my main speakers. However, I am somewhat confused about how bi-wiring works given that the speakers have internal crossovers and the signals received by them have the same full frequency range going to both sets of terminals.
I confess that I don't see any difference from single wiring in terms of the speaker's performance. What am I missing?
