The speaker DC resistance (0 Hz) has very little to do with the speaker impedance from 20Hz to 20,000Hz. Measurement is fine but it won't lead you to the answer.
From the other thread, since you are thinking about running another set of speakers with the 901s.
If you use the 901 EQ you will NOT be able drive any other speakers with that power except Bose 901s because of the eq added to the signal to get the 18 midrange drivers to do bass and treble. That eq will blow up a pair of Klipsch. The Bose EQ is a very highly boosted 'smile' on an eq. Plus 20 dB in the treble and nearly the same on the bass end. Amp killing asking for all that power.
The EQ is best used in the signal processor input output on the SX-1980, that is what the sig proc is for on that unit, the Bose EQ or Pioneer EQ and those types of units.
If you get a second set of speakers you need a second set of power channels. Use the EQ with one of them and not with the other one (unless they are 901s), then you can put the eq between the preamp output and the power amp input. But for everyday use, one set of speakers, the 901s that is the wrong place for the eq, it is a noisier position to put it.
Why do you need to know the ohms of your receiver? What does that mean or what are you trying to ask?

I did just confirm the sx-1980 is wired parallel internally. When I'm running A (bose 901's) and turn on B(nothing hooked up to it) it doesn't kill my sound. Is there any real way to test the ohms of my receiver.
