Thanks Brad. I've spoken with several people and they gave the same info. you provided to me. A 16 ohm speaker would NOT have a resistance reading of 6.9
Impedance = Resistance + Reactance. Resistance of the wire, whichis then wound in a coil having mostly inductive reactance.
Except it's not plain addition, but vector algebra; Resistance2
Gerald Weber suggested there was a fixed ratio of d.c. resistance for a given speaker impedance, but that's just wrong. There is
a typical range, but it really depends on how the speaker manufacturer designed and constructed their speaker.
