All sound is measured and delivered as a wave form. "Peak Power" refers to the amount of power used when reproducing the highest point (or peak) of each wave. This number will always be higher than the RMS power, which is the total amount of power delivered continuously. Many multimedia speaker manufacturers now heavily market and promote "Total Peak Power" specifications as the primary measure of speaker system power. However, comparing RMS power between systems (as required by the FTC) is the most meaningful way to compare system performance.
