OK Glenn, maybe you can't be bothered (yeah, right) but I can. I've
done the work for you and simulated the two effects - biwire, or
parallel wire, joined at the far end - in PSpice. The results
vindicate my position completely.

No they don't.

You've only placed a "lossy" cable on one leg of the speaker cable. So
you've got effectively a 5 metre run of cable from the positive speaker
output, then a short (as close to zero ohms as possible) run back to the
ground point on the amplifier.

God almighty ! Don't you know that's the same as modelling with the resistance
equally distributed ?
