Okay, Bob, I'm going to add a DC component, but I'm not going to
tell you that this DC component is really a millihertz-frequency sine
wave. How will you know the difference? Just what IS the difference
over a time period of one second?

Enough. :-)

Woah, wait a second, you're hand-waving your way out of this one
without actually addressing it.

Please explain how, exactly, a DC component changes the "source" of
the signal, but when there's an infinitesimally small frequency, so
small that one can't detect it, but that technically is not DC, the
"source" of the signal suddenly "snaps back" to be the center, or zero
excursion point, of the driver?
