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.
