Nope. Didn't understand a word of that.



** Really ??

So " I squared R " has no meaning in your world ?

The resistive losses that increase a speaker's mid band,
resistive impedance beyond the DC ohms value are also mysterious
to you ?

A multiplying power meter, using analogue multiplier ICs,
is also a mystery ?

Where have you been hiding Don.

Under a rock?



I squared R has plenty of meaning. Unfortunately a speaker is not an
R. It's an X.


** However, the copper voice coil IS a simple resistance hence I squared R applies. You did not read my post.


Your measurement method, applied to a pure capacitor, would
apparently yield a power level.



** Not at all, an ideal capacitor has a resistance of zero.

Try reading my post, it is very clear.
