Every year or two CU tests popular speakers, and while most speakers

opinions should to be taken with a grain of salt, measurements are
measurments, and not opinions.



CU may be measuring the DC resistance of the speaker, and that will not be
the
same as Impedance, which is AC resistance and changes all over the place
with
frequency.

Just accept the manufacturers rating and don't worry about it


I have measured many loudspeaker systems en still do. My advice: Don't ever
trust the manufacturers ratings.
