Am I right in thinking that the resistive component of the speaker's
impedance is effectively in series with its inductance? Say, 5 ohms
for an 8 ohm speaker? If so cable resistance is not so frightening
for domestic runs.
It's not so difficult to provide negative output impedance to counter
the wire+speaker resistance. This can significantly increase damping
and is sometimes used in powered 'active' speakers where all
parameters can be controlled.

Never thought otherwise. That's obviously never been what we do here. ;)
But resistance does matter, so a good cross section such as 2.5
mm^2 puts you on the safe side.
What I was trying to ask is, what's the real problem with
resistance, especially with regard to a passive speaker and a
modern, A/B class solid state end stage? I mean, I don't really see
cable resistance shifting their operating point much, even with
feedback, within the audible range.
What is it that I'm missing?
