Power Handling
Power handling is the electrical input power a passive transducer is rated to tolerate under specified test conditions.
Continuous, programme and peak ratings describe different conditions and must retain their qualifiers. The rating is separate from recommended amplifier power and from mains consumption.
Power Handling — Loudspeaker
For a passive loudspeaker, power handling describes an input limit under the stated method, not the acoustic power it produces. The signal’s frequency content and duration affect stress on its drivers.
Compare the same rating type and test basis rather than a peak figure against continuous power. An active speaker’s built-in amplifier output is a different specification. The number is not an unconditional guarantee against damage from every waveform or operating condition.
Power Handling — Super Tweeter
For a super tweeter, power handling applies with the required high-pass filtering and other stated conditions. The high-frequency driver is not intended to receive the same unrestricted signal as a full-range loudspeaker.
Compare the filter frequency and slope attached to the rating, along with whether the figure is continuous or peak. Do not apply a filtered power rating to an unfiltered connection. Keep a recommended system-amplifier size separate from the driver’s own input-power rating.
Power Handling — Headphone
For headphones, maximum input power describes an electrical rating for the transducer, often in milliwatts. It does not state the power required for ordinary listening or a suitable listening level.
Compare continuous and peak conditions and use the correct units. Headphone sensitivity is a separate specification, so equal power ratings do not imply equal acoustic output. The amplifier’s available power should not be mistaken for power constantly delivered to the headphones.
