Tech Talk RMS versus Peak Power: Peak power is measured by a brief musical burst (such as a crashing cymbal) and refers to the maximum amount of power that a device can produce from such a burst. However, a more reliable specification is RMS (root square mean) power, which measures the maximum continuous power that an audio device can produce. With a higher RMS figure, your music will sound cleaner as well as louder.
