There is a Bi-amp function in my A/V Receiver.

Greetings all,
I just discovered that my Pioneer Elite Receiver has a biamp set-up feature using its own unused back channel speaker terminals. It still puts out a full range signal though, so the high and low taps on my speaks will still get the same signal. Is there any merit to doing this. Or could it be harmful to send a full range signal to the tweeter section of my Klipsch Epic CF3's. Or does the crossover still cut out any part of the signal that could be harmful.
My Onkyo 876 also allows this. I can also "bridge" the two channels for greater power (alas, the speaker must be 8 ohms -sorry Thiels).
Your speaker's crossover will pass only the frequencies the tweeter can handle (assuming your speaker came with the bi-wire terminals connected (some kind of metal strap or jumper wires?).
Don't forget to remove the jumper if you try this. Otherwise Dweller is entirely correct. All it will cost is another set of speaker wire and there is a good possibility of better sound
Bi amping is not so great on a two way system. If you had a three way, the woofers could use a separate amp section from the mids and tweets. Sensible.
Using a separate section to run just tweeters is a waste of time IMO.
I have never had to disagree with Elizabeth, but here goes: Bi-wiring produces different results with any speaker. It seems to have more to do with the crossover than anything else. I have bi-wired several brands of two ways that showed a tremendous improvement.
Thanks for the replys. They are now biamped and it does add to the sound. I have had them bi-amped before to good effect, but then, only the lows and highs were going to each set of taps. It was the full range signal going to each that made me pause.
