This work aims to provide designers with a method to develop a requirements specification for power supplies and amplifiers in active loudspeakers. The motivation is to avoid over-sizing and unnecessary cost. A realistic estimation of the power supplied during playback of audio in a given loudspeaker is obtained by considering a wide range of audio source material, loudness normalization of the source material, crossover filtering, driver characteristics as well as a perceived maximum loudness/volume level. The results from analyzing a sub-woofer and a woofer reveals the peak power, peak voltage, peak current, and apparent power—thus providing a solid foundation for a requirement specification.
