Measuring impedance with multimeter

Thanks for the reply. A internet search indicates the measurement should be in the ballpark ( ie 15 to 20%off). 

Would different or more complex speaker designs give widely variable levels of accuracy?

As I stated, the little elac debut reads exactly  6 ohms .... as advertised;-)

Even if the frequency- impedance graph indicates the lowest impedance as 12 to 14 ohms?

Thanks for all of the explanations and links.

For non EE types, what sort of equipment would be needed then to get a reasonably accurate measurement?

This?

Thanks in advance

Bsmg, as I stated in the prior post, the graph provided by the maker of the speaker never dips below 12 ohms over the entire frequency spectrum. And I never mentioned anything about what taps I have.

So is there no instrument that can be acquired without breaking the bank for nonEE to broadly measure impedance, or in this hobby where snake oils are rampant does everyone blindly except vendor claims?

Speakers are expensive and impedance matters ;-)
