Peak / Maximum Power Output
Peak power output is a stated short-term power capability under the specified conditions.
Peak, dynamic, music and burst labels can use different methods. They should not be treated as interchangeable with a continuous per-channel rating.
Peak / Maximum Power Output — Power Amp
For a power amplifier, a peak rating can describe output available during a brief test or signal demand. The load, number of channels and duration are essential to interpreting it.
Compare only equivalent methods and keep the maker’s label attached. A large peak or marketing maximum should not replace the continuous rating used for amplifier-to-speaker matching. Missing duration or test conditions limit direct comparisons.
Peak / Maximum Power Output — Subwoofer
For an active subwoofer, peak amplifier power describes a short-term electrical rating of its built-in amplifier. It does not directly state maximum acoustic output.
Compare the same rating method and distinguish it from continuous amplifier power or mains consumption. Driver, enclosure and limiting behaviour also affect output, so a larger peak-power figure alone does not establish deeper or louder bass.
