I don't have a inductance meter, I suspect these 2 things are
inductive, because a pair of capacitive ( 60 +ve & 60 -ve
wires are interwoven ) speaker cable ( made by UK's
Monitor Audio in 1983 ) can produce less distortion from
the same m-c spkrs & amplifier than straight ( not inter
woven ) spkr cables can, such that FM broadcasts sounds
more like CD`s.
I presume this is because this cable's capacitance reduce m-c
spkr & crossover networks' inductance, so power factor (
between amplifier & spkrs ) is nearer to 1.
Does any1 here know better ?
I suggest that you refer that question to audiophile groups, where art
reigns over science.
The effect of increasing speaker cable capacitance from a few tens of pF
to a few hundreds, with an extremely low source and load impedance, is
going to be infinitessimal.
Hence the need to go to audio groups where you will find people willing
to pay a hundred quid for a speaker cable, because they believe it works
better than a ten quid one..
Your problem isn't to do with induction, but intuition..

A speaker will have the equivalent of leakage reactance. Ideally, the air
driven by the voice cone will generate an acoustic wave who's load shows up
as resistance on the voice coil terminals. But speakers are not ideal.
For the crossover networks, it probably depends upon how implemented. Again,
an ideal crossover will look resistive.

1983? Your cables are dangerously worn, even if you have been
interchanging them left-to-right channel every three years and reversing
direction at least every 6 months, as I'm sure your manufacturer will
tell you. You must replace them at once, else you might as well be
listening to wax cylinders cranked by an arthritic monkey. .
Well, sure in a grossly simplified analysis, but if you are planning on
listening to anything higher quality than an earpone plugged into a
radio shaped like a fuzzy dog, you'll obviously need to consider Bessel
functions of the Poitier reactance (an absolutely key concept to
understanding the fundamental principles of audiophilia). .
When you ordered your cables, did you include the recommended sketch of
the layout in your listening room, so that the cables can be properly
compensated for the Hall effect on the electron transit time? Careless
installers have been known to neglect the effect of the Earth's magnetic
field; installing a properly compensated pair of East-West cables
instead of the North-South variety will reveal new lucidity of the
midrange and an appealing truculence of the base, as well as new
confidence of the higher range.
But of course you knew all that.
