I'm reading a bunch of stuff in these posts that doesn't make sense. The reason bi-wiring works is due to the finite but definite level of resistance a wire has. If you send a current to the tweeter and woofer and the crossover splits it and then the signal returns via the "ground" speaker wire. That return post from the crossover will develop a voltage. Because the current is flowing through the wire that has a resistance. Bi-wiring improves the sound because the tweeter return path is on it's own wire and therefore the voltage at the crossover is due only to the tweeter current and you will not get intermodulation with the current flowing through the bass wire (the voltages sum when using one wire for both). The net result is that the larger currents that flow through the bass network do not affect the amplitude of the tweeter signal.

Jkorten, since you opened the can of worms, here is something else for you to read that talks about more than just the intermodulation issue. Bi-wire, not only an advantage If you like bi-wire, great, I'm happy for you. In reference to the OP, I prefer single wire with jumpers of the same wire. |
IMO bi-wiring is one of the few contentious issues in audio that there is no point in analyzing or debating theoretically. There are many subtle technical effects that can come into play to a small degree, a lot of them having been mentioned above and in the links that were provided, and their net result will, as I see it, undoubtedly be system and listener dependent. Regards, -- Al P.S: Kijanki, don't forget the 2pi factor for inductive reactance (which your post 4 years ago correctly reflected). 35 milliohms should be 220 milliohms, and Z = 222 milliohms. |
