What has the resistance of the voice coil got to do with this? It is a

of the reactive component that is of interest here.



** The topic is measuring *power dissipation* so resistance is everything.

The power dissipation in a loudspeaker is approximately 85% in
the voice coil with the remaining 15% in the suspension, eddy
currents and radiated sound.


This is starting to get quite surreal.



** FFS sake Don, you are making an utter ASS of yourself.

Hee - haw.....


The current that flows depends
on the impedance, not the resistance. At some frequencies the
impedance is higher, resulting in less current. At others it is lower,
making more current. At the resonant peaks the resistance (not
reactance) of an 8 ohm speaker can approach 50m ohms. Between
resonances at is probably down around 4 ohms.


** The current flow is as read on true RMSs, wide band, current meter.


Take a look at one of my measurements of a speaker - a Mission 774.
There are two plots. One is scalar impedance, and the other is the
full picture on the complex plane. If you can tell me what resistance
I am supposed to multiply the current by on a broadband signal I will
give up.


** I have described just that, in detail, here, several times.

Don has NOT answered any of my points, he ignores them and posts drivel just to keep to argument going.

A old and very worn debating cheat from a congenital cheat.

FYI to all readers:

There is no fool like an old fool and Don is a DAMN FOOL.



OK, you aren't prepared to deal with reality. You reach your limit of
electronics ability at DC measurements, and beyond that, into real and
imaginary axis impedance you can't function. I'm not bothering to
explain any further because you won't get it. And of course now your
standard ad hominem has started we know what comes next. What is in
store for me? Is it cancer, or should I just FOAD because I am
autistic, ASD?
