They have letters from men, they are engineers. I know not if they are
"registered" what ever that means. Not much emphasis seems to be placed upon
analogue these days in the schools, or at least that is what they tell me.

" No, you misunderstand the basics here, as the *impedance* of the load
will vary dramatically in the bass region, thereby affecting how much
power is required for a given SPL. It is therefore a moot point
whether the load will require more amps or more volts at any
particular frequency."

Someone sure is misunderstanding someone here... If you claim that an IC
gives you more bass, sure you can compare the current in the 2 ICs, but the
only way to know would be to filter out the low frequencies where it is said
they are hearing more bass, and see if there is in fact more current flow
there.

Voltage is determined by the amp, though the load can cause a drop in the

amp,
but the load, if the speakers want more current to move a lower

due to further excursion of the driver, then it will demand more current,
though not more voltage as it cannot demand voltage, from the source.

I work
with a LOT of EE types, it does not mean they understand electronics, the
ones I work with know PLC's, 4-20 loops PID loops, etc, but not
electronics.
That is why I often find myself correcting them on this very issue. It is
not that they are stupid, it is just that this is not their area of
expertise.

Excuse me, but if they are registered professional *engineers*, they
certainly *should* know electronics. You seem to be describing C&I
technicians, which is a different matter entirely.

For there to be "more current flow" with one cable, there has to be more
voltage measured across the load. Why is this difficult to see?

Are you saying that there can be more current flowing into the load with
the *same* measured voltage across the load? Does "impedance" mean
anything to you?

You realize that we are not comparing speakers. We are talking about
differences in bass response between two cables.

Drugs in my younger days, I have the flue, I really do, had a flue shot, but
that was a waste. I was thinking about a music signal into a full range
speaker.

I have already addressed this in another post, there is no need to argue it
in 2 posts.

Actually I was thinking of IC's between components more than speaker cables,
once you get into a good cable, I have not tried 12 gage wire so I cannot
comment, but once you get into a Goertz, Kimber, Monster, et. al. I cannot
hear a difference, but I have heard differences in IC's.

In my recent e-mail, which part of 'just use a low-frequency sine
wave' did you fail to understand? This ain't rocket science! If there
really were any differences, they would be *easily* measurable. The
truth is, there aren't - *especially* in the bass region.
