I know this may be a silly question, but here it is nonetheless.

IF you biwire, do both wires carry the same signal? Or does the wire somehow know not to carry the 'other' frequency range? If you have a connection to the HF part of the crossover, do only HF frequencies make it TO the crossover? Opposite for the lows.

OR,

As would seem reasonable to me, the crossover selects and ALL the frequencies are available to it at the speaker terminals.

Which is correct?

The full spectrum voltage signal will appear at both sets of speaker terminals but the currents in the two sets of wires with have different spectra (I expect*).

All the frequencies make it to the crossover but the impedance of the high pass filter, at low frequencies, is high so there will be little current at the low frequencies flowing through the wire and visa versa for the speaker wire feeding the low pass filter half of the crossover.

Thanks So Mucho.
NOW it makes sense. The question originally concerned biwire. Now it would theoretically make sense to optimize EACH 'way' for the frequency band intended......At least to the extent such a thing would be possible.

I expect you are correct!
Tre`, above, helped clear the mush fro what I HAD been hearing.

Thanks to Tre` and Duke.

Got this figured out now and can account for SOMETIMES biwire actually sounding better than single wire.
