Jb/Gb, you really need to clarfy why and how you measured impedence. also i envy you guys for having the best install tools and test & measuring equipment. now im sure you have the AZ audio meter. thats drool worthy dude.

There is a slight difference of the negligible order. Thats why manufacturer state it as nominal impedance as the impedance of loudspeaker / driver variates according to the frequency. You are right impedance is frequency dependent, it is actually the resistance value offered at a particular frequency of AC sinewave. Yes we do have AZ Comp Audiometer.
We do it only in the case of very high end equipment by using test tones with speaker hooked to amplifier and DMM for measurement. For easier measurement one can use Impedance Bridge.

Wish we could

The component level stuff is available on special order of multiple pieces only. The Sonus caps and Inductors are expensive.
