bi wiring

Just as counterpoint, some of Theo's statements are simply not true. For example, "I beleive that the benefit of bi-wiring is that a seprate run from the amp output allows the frequencies to seperate according demand." Cables cannot do this without a crossover.

And, while I have yet to heard any advantage to biwiring (as long as the original wire is adequate), there is no significant disadvantage to it. Try it.

"Your statement is correct, but the 2 cables are indeed driving a crossover, inside the speaker. The frequencies divide in the cables based on the impedances each is driving, with all frequencies taking the path(s) of least resistance. The 'high' cable is driving impedance that rises as the frequencies decrease and hence passes a lower proportion of lower v. upper frequencies, while the 'low' cable drives higher impedances as the frequencies increase and passes a lower proportion of high frequencies. (This all works the same way in passive biAMPing.)" Hmm. Depends how you measure it. If you measure voltage, you won't see it. If you measure current, you will. So, it may be a semantic issue and the intermodulation red herring is debatable. As for passive biamping, the only effect MIGHT be in the output stage that sees the load but intermodulation is possible in all the other stages.

Overall, I have yet to see a reliable technical argument for any significant enhancement due to biwiring nor have I ever experience such an enhancement subjectively. OTOH, as I said above, since there's no downside but cost and bother, everyone should try it and trust his own ears.
