Efficiency

In a general sense, efficiency is the ratio of energy output to the total energy input, expressed as a percentage. In speaker systems, efficiency refers to the ratio of total acoustic watts radiated to total electrical watts input. Home speaker systems of 1% to 3% efficiency are typical, while larger horn-loaded sound reinforcement speakers sometimes reach 10% efficiency or more. Efficiency should not be confused with sensitivity, which measures onl y the on-axis sound pressure level in relation to electrical input power.
