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.
