Abstract
This work aims to provide designers with a method to develop a requirements specication for power supplies
and ampliers 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 ltering,
driver characteristics as well as a perceived maximum loudness/volume level. The results from analysing
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 specication.
