Thanks.
Are you sure you're not confusing the two terms? Bi-wiring is running two wires to the exact same post from the amp/receiver to the speaker. So two wires from the negative post on the amp/receiver to the SAME
negative post on the speaker. same thing for the positive posts. Bi-amping on the other hand, is running a single wire from the negative post from the amp/receiver to the first negative post on the speaker same for the positive post, then running a another set of wires from a different amp to the second set of posts on the same speaker. You MUST remove the shorting plates connecting the two set of posts on the speaker though.
Bi-wiring (running two cables to the same posts) is pointless. Just use the proper size cable to begin with and you'll be fine as another poster had mentioned.
Bi-amping has its benefits, but only if properly implemented. This means removing your speaker's internal passive crossovers, running an active crossover and using a separate amp channel per set of posts on the rear of the speaker. Separate amp channels on a receiver capable of bi-amping does not qualify as separate channels here as they are both sharing the same power supply and are not truly discreet channels. Not only that, but you'll be sending out the full frequency range out to both speaker posts which largely negates the benefits of bi-amping.
I say you may be confusing the two terms since you mention having extra "bi-wires" lying around. I'm assuming these are just four or more wires in the same jacket. Then you go on to mention high end speaker manufacturers making the option for "bi-wiring". Bi-wiring is not an option that needs to be made available by the manufacturer, but bi-amping does. You can bi-wire ANY speaker from the lowest cost to the most expensive. Heck, you can bi-wire a cheapo set of headphones. Bi-amping, on the other hand, requires the manufacturer include two sets of binding posts (two negative and two positive) for a total of four.
Sorry for the babbling, but I hope I was clear in my explanations.
