Phil,

I am not stupid enough to understand your "engineering principles".

But I am stupid enough to understand transmission lines, so BITE ME!

There is absolutely no good reason to try and make your speaker wires
8 ohm transmission lines.



** There is - but you are too dumb to see it.


There are more than a few good reasons not to!
One is the capacitance per foot would likely cut your highs.

** What rot.


Another is the impedance of your speakers is only 8 ohms at dc.


** More rot.

And another is the impedance of your amp is only a small fraction of an

ohm.


** Huh ????????????



The reason transmission line matches are important at RF frequencies
is mostly to do with the voltage changes along the line caused by
"standing waves".



** True enough for FRO - but irrelevant for audio and most video lines.



These variations occur at 1/4 wavelength intervals
1/4 wavelength at audio frequencies is on the order of 30,000 meters/4.



** Do you understand the word "irrelevant" ???????


A really long distance. Long enough to be entirely insignificant.



** I am thoroughly sick of arguing with ******wit** ham radio jerk-offs
about transmission lines.

Read closely:

Standing waves are NOT the issue for audio or video, something
**else** is.

That something is capacitance and inductance.

For audio and video *signal* lines cable capacitance attenuates the
high frequencies.

For loud speaker lines cable inductance does the same.

A line impedance matched to its characteristic Z at the receiving
end does NOT lose highs.

Such a line is resistive as a load.

Capice ???????
