Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts. The electrical power delivered to the loudspeaker, together with its sensitivity, determines the sound power level generated (with the rest being converted to heat).
Amplifiers are limited in the electrical energy they can amplify, while loudspeakers are limited in the electrical energy they can convert to sound energy without distorting the audio signal or damaging themselves. These power ratings are important to consumers finding compatible products and comparing competitors.

Famous quotes containing the word power:
“People ask me: Why do you write about food, and eating, and drinking? Why dont you write about the struggle for power and security, and about love, the way the others do?... The easiest answer is to say that, like most other humans, I am hungry.”
—M.F.K. Fisher (19081992)
