RMS is an acronym for “root mean square.” In terms of audio reproduction, RMS indicates the average power output of a loudspeaker. A speaker’s RMS output is measured in watts and is typically listed both on the speaker’s packaging and within the speaker’s documentation. The higher the RMS wattage, the more powerful the speaker. If you aren’t sure of a speaker’s RMS wattage or want to verify a claim made by a manufacturer, you can determine RMS wattage yourself. Tips Writer Bio
