Where does this come from? I've never though cable geometry matters much
at all, unless your pumping so much power through a cable over such a
long distance that you have to worry about ohmic heating and the like.

my gut feeling had always been that in the presence of HF cues, you
can get away with sloppy LF cues (as in, drive all your subs in mono
for maximum ooomph, but the kick sound of the kick drum will make sure
it's localised properly). maybe i was wrong.

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.

I'll use less than 10 meters of cabling to drive 10W max in each tiny 6
ohms speaker. So I'm not worried at all. Gauge 14 or 16 should be fine:

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
If you do not do something tricky with the amplifier--
and no commercial consumer audio amplifier intended for
universal use does this trickiness, or none I am aware of--
then the cable impedance operates as part of the amplifier
output impedance. This means that the amplifier
will not be flat in
