Requirements Specication for Ampliers and Power Supplies in Active Loudspeakers
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.
