It doesn’t work any different than non bi-wired. From an electrical engineering standpoint, the amplifier terminal and the two speaker terminals are the exact same node. The only advantage IMO of bi-wiring is that the sonic signature of a speaker can be customized by inserting resistors between the the high and low terminals. This adds additional nodes between the amp and the crossovers and changes the filter parameters (that is, it's designed that way -- you shouldn't do that yourself).
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?
