The speaker system should re release various music programs with high quality. According to the properties of the music signal, its peak factor is about 10-15dB. From the perspective of ensuring sound quality, the power amplifier should have no restrictions within this dynamic range, that is, the Z-output power of the power amplifier should be 5-8 times the rated power of the speaker. Although this power configuration has good sound quality, it requires a significant investment, so the power ratio is generally set at 1-2 times the rated power of the speaker unit. The range of 1-2 times may be vague, so we can provide you with a more specific experience.
1．In some low demand and limited investment engineering power amplifiers, the power should be at least equivalent to the rated power of the speaker, but great attention should be paid to maintaining sound distortion. A power configuration that is too small may not damage the speaker unit, but this is not the case. Too low power can easily lead to overload, reduce waves, generate a large number of harmonics, and burn out the high-frequency unit.
2．For ordinary engineering, it is recommended that the power of the power amplifier be 1.5 times, and the power of the low-frequency part Z be 1.5 times or more, in order to obtain sufficient power sense.
3．Require extremely high sound, such as studio surveillance, concert halls, etc. ， Z ideal is twice the power of the speaker. (This is consistent with one of the recommended values in the connection standards developed by the International Electrotechnical Commission (IEC).) The design of power amplifiers does not have rigid standards and is entirely dependent on investment budgets and sound quality requirements.
