Speaker system and power amplifier configuration

The speaker system needs to reproduce various music programs with high quality. According to the properties of the music signal, the peak 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 maximum output power of the power amplifier should be 5-8 times the rated power of the speaker. Although the sound quality of such a power configuration is very good, its investment will be very large, so this power ratio is generally set at 1-2 times the speaker unit. rated power. 1-2 times this range may be out of space, we can give you a more specific experience.

1. In some low-demand and limited-investment engineering amplifiers, the power is at least equivalent to the rated power of the speaker, but pay attention to keeping the sound undistorted. A power configuration that is too small does not seem to damage the speaker unit. In fact, it is easy to be too small Overload clipping occurs, generating a lot of harmonics and burning the tweeter.

2. General engineering recommends that the power of the power amplifier is 1.5 times, and the bass part is better than 1.5 times, so as to obtain a sufficient sense of power.

3. Highly demanding sound places, such as studio monitors, concert halls, etc., are ideally twice the power of the speakers, (this is consistent with one of the recommended values ​​of the mating standards established by the International Electrotechnical Commission IEC)

There is no hard standard for designing the power of the power amplifier, which depends entirely on the investment budget and the requirements on sound quality.
