proper voltage? When you connect speakers to an amplifier, do you
worry about what the source impedance is, so long as it's low enough
to not materially affect damping? If not, why would you worry about


I would not go there on the audio . The speakers do need to match the design
of the amp just as the load on a transmitter needs to match the design
impedance. Most power output devices are designed to produce maximum power
and /or minimum distortion into a specific load.


Just my point, Ralph... you should worry about your speakers being
within the range of LOAD impedances that the amplifier is designed
for, but you seldom would worry about the SOURCE impedance. You
should worry about the antenna-load you present to your transmitter or
amplifier being within the range of impedances for which the
transmitter or amplifier is designed, but why worry about the
transmitter or amplifier source impedance?

(Some folk worry about audio amp damping factor, but it tends to be
grossly overemphasized...see postings over the years by Dick Pierce in
the audio groups for the simple explanation why it doesn't matter all
that much.)
