When you folks are talking about "impedance" in relation to speaker
(and other sound-system) cables...are you talking about the impedance
of the cables as a transmission line? If so, does the frequency of
the tramsmitted signal get involved at all? As well, does this mean
that the impedances of both the output of the signal source and the
input of whatever is being fed would have to be matched to the
cables' characteristic impedance? I used to use 72-ohm transmission
line to feed a half-wave dipole, with a pi-network output feeding
my transmitter signal to the "house end" of the twin-lead (or 300-
ohm line to feed a "folded dipole")...But is the upshot of this
the possibility of having "standing waves" on speaker cables?
