Bi-Wiring Center as a left and right

If the speaker supports biwiring, it will send one input to the woofer and the other to the mid/tweeter.  If you wire each to a different channel, you will get lows from one and mid/highs from the other.  Not a good idea.

Cleeds, yes, biwiring sends the same signal to each input of the speaker, from the amp, but that’s not what Kal (kr4) was referring to. He was saying, correctly, that "it [the speaker] will send one input to the woofer and the other to the mid/tweeter." And his subsequent sentences were also correct.

To the OP, I’m not sure exactly what connection configuration you were envisioning between the amps and the four terminals on the speaker, but none will work correctly, and many will risk either blown fuses, self-protective shutdowns of the amps, or damaged amps.

Not a good idea, as Kal indicated. Regards,

No, you're thinking of biamping. Biwiring sends the same signal to each. They are two different things.

No.  From the speaker end, it is the same thing.

Bad idea.

If you want L-C-R or L-R to the center, get a quality passive soundbar such as one of the two GoldenEar SuperCinema 3D models (http://www.goldenear.com/products/supercinema3d) and connect the amplifier outputs to the appropriate soundbar inputs. I’ve heard it and it’s really good, esp. if you add a GoldenEar sub.

Doing it the way you propose will give you a very unsatisfactrory sound--low frequencies from one channel and high frequencies to the other sent to the center. Depending on the sound mix of the source, it may work OK on some shows but be unintelligible on others.
