** So this is what all the Doppler Distortion fuss is about ????

A tiny bit of phase jitter, which at 5 kHz rarely amounts to more
than a few degrees ??

It's not a lot. The most important thing is that its swamped by all
the AM distortion.


** Which, unlike the puny phase jitter, is veeerrrryy audible.

Agreed. With a bullet!

But net it out -we're saying pretty
much the same thing, Phil. The Doppler distortion is there but its
small.

** I found with my test that much of it goes away if you put the
woofer cone at right angles to the mic.

Again, per theory.

I think the guy who brought up Doppler as some kind of a serious
problem did so a few weeks ago. He used Doppler distortion as a
justification for not liking long-excursion woofers. In the end he
admitted that he used 2-way monitors with either 6.5 or 8" woofers,
and no subwoofer. Ironic enough?

** Must just love all that IM.

He even bragged about all of the cone motion, when this little tyke was
driven with LF, I believe he even specifically mentioned 30 Hz.
