If you consider sensitivity to mean SPL as a function of >voltage, then the original theory is correct: the higher impedance >speaker would produce lower SPL at a given voltage. However, >sensitivity generally refers to SPL as a function of power. As John >Fields said, if the efficiency (dB @ 1W, 1m) You can't be god, because that is wrong. Efficiency relates power in and *power* out. SPL is not power. -- Regards, John Woodgate Tel. +44 (0)1268 747839 Fax +44 (0)1268 777124.
