Loudspeaker efficiency versus sensitivity

The sensitivity of a loudspeaker is the sound pressure between 125 Hz (250 Hz) to 4 kHz (8 kHz) at a specific distance - when you have a constant voltage - measured in dB per watt and meter. Mostly it is the voltage of constant 2.83 volts, the distance is 1 meter, at 8 ohms nominal impedance. For instance the sensitivity of a good 8 ohms loudspeaker is .........
