Many years ago I believe I heard of a means to connect stereo speakers
to an amplifier/tuner by use of home electrical wiring as the speaker
wire. As I recall, there was some kind of interface device that
connected a wall outlet to the amplifier and another that connected
the speakers to wall outlets which allowed for easy placement/movement
of speakers without the need for specialized wires for connecting
them.
I have searched and searched and find nothing that refers to such a
means of connecting speakers.
Was this an idea that just didn't work, or am I not using the correct
search terminology?
Thanks for your advice. Lee

Similar probably to the 'FM wirelss' intercom systems that use/used
the house wiring. Not widely adopted AFIK.
Tried one once and found that if the intercom remote terminals were on
the same or adjacent circuits it worked OK.
But if the remotes were each on different outlet circuits and or
different sub circuit breaker panels performance was poor and noisy.
With so much noise (and possibly digital signals) floating around on
the electrical supply today it might be very tricky.
Just an opinion though.
Speakers (unless you are handling an eardrum shattering 1000 watts or
something) can work on almost any kind of wire. So pretty easy to
snake some suitably light coloured 18 or 20 AWG (Bell or speaker wire)
anywhere also relatively cheap.
What is the application?
