Hello. I don't know if you are the person who moderates this forum or if you are actually the person behind these Pi speakers.

Please forgive my not knowing. In any event I think you may be able to answer my question.

I do not see the Impedances listed in the areas where you give the specs of the individual speakers. Have I missed something here? Are they all the same?

I suspect I just can't find the right place to tell me. It is an important factor to me and I suspect many others.

If you could help me out here I would appreciate it. Thank you.

Eight ohms is the advertised impedance of all motors used in π Speakers. Advertised impedance is listed on the specifications sheet for each motor on the π Speakers website. But advertised impedance is not a terribly good indicator of the actual impedance of a motor. So impedance at resonance or "Zmax" is also shown, which is a critical determiner of performance on amplifiers having low damping factor like SET amps without negative feedback often have.

Thanks for responding Mr. Parham. I think you answered my questions, but I have one more.

What is a piezoelectric? Actually I don't need to know much about it, just how does it effect the Inpedence of the speaker as a whole? Does it have any resistance on it's own?

A piezoelectric device is one that uses a quartz crystal as a motor/generator. You can get exact specifications, including the impedance curve, at www.PiSpeakers.com/KSN1041.htm.
