Now that multiple people have told the OP bi-wiring doesn't do anything for their setup, I'll kick in my $.02. With my speakers, I get a subtle but definite improvement. Less so with decent quality jumpers replacing the OEM plates, but still a slight improvement. Try it with your speakers and see if it does anything in your rig. All it costs is a little time. If you have to buy cables to do it, the difference, if any, probably isn't worth that much.
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?
