'''Audio power''' is the [[electrical power]] transferred from an [[audio amplifier]] to a [[loudspeaker]], measured in [[watt]]s.  The [[electrical power]] delivered to the loudspeaker, together with the speaker's [[Electrical efficiency|efficiency]], determines the [[sound power]] generated (with the rest of the electrical power being converted to heat).

Amplifiers are limited in the electrical power they can output, while loudspeakers are limited in the electrical power they can convert to sound power without being damaged or [[distorting]] the audio signal.  These limits, or [[power rating]]s, are important to consumers in finding compatible products and comparing competitors.<!--[[User:Kvng/RTH]]-->
