To borrow spiffnme's phrase from a recent post, I had a moment of clarity and thought I'd share my insights.

Right, Peter. The crossover circuitry for the woofer and tweeter is always separate; bi-wiring has nothing to do with it. The wires carry the full frequency signals until they've been through the speaker crossover and it doesn't matter whether the wires get split at the amp output terminal or just before entering the woofer and tweeter sections of the crossover.

As for bi-amping, have a gander at this article.

Is it me or does everyone hear that echo in here?

Is it me or does everyone...

Oh. Sorry....

how about coiling large lengths of speaker wires to the fronts placed in front of the sub for reveberation effects. imagine the wire vibrating and really exciting the signals to the speakers...or maybe too much coffee already this morning
