@c13g2000cwb.googlegroups.com:
Every year or two CU tests popular speakers, and while most speakers
claim to be 8 ohms, CU finds most to measure 4 ohms. Although CU's
opinions should to be taken with a grain of salt, measurements are
measurments, and not opinions.
The good thing about speaker impedance is that you can quote almost any
figure you like, and be able to back it up with measurements. Unfortunately
the frequency at which that figure applies is never quoted.
CU are probably right if they are talking about minimum impedance, however
the only *useful* measurement is an impedance Vs frequency graph, then you
can decide for yourself what is relevant.
