Hi Ralph,Most loudspeaker manufacturers specify efficiency expressed as number of db 1 watt/1 meter rather than as a percentage.
Actually most speaker manufacturers don't specify efficiency whatsoever.
Sensitivity, is generally voltage, as in 2.83. Efficiency on the rare occasion, is usually expressed as percentage.
And to remain "nice", I best refrain from comment on your impedance/amplifier "brightness" "theory".
cheers,
AJ
