Audio power
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 being damaged. These power ratings are important to consumers finding compatible products and comparing competitors.
