The speaker needs to reproduce various music programs with high quality, so according to the properties of the music signal, its crest factor is about 10-15dB. From the perspective of ensuring sound quality, the power amplifier should not have any limiting in this dynamic range, that is, the power amplifier The larger output power of the speaker should be 5-8 times the rated power of the speaker. Although the sound quality of this power configuration is very good, its investment will be large. Therefore, the power ratio is generally set at 1—2 times the speaker unit rated power. The range of 1—2 times may be out of space. I can give you a more specific experience.
