Three principles of matching speakers and amplifiers summarized by audiophiles:

 

First, pay attention to the power matching problem. In theory, the rated power of the speaker must be equal to the rated output power of the amplifier so that the equipment can work properly. It is recommended to prefer a small horse instead of a small horse. When conditions permit, you can choose high-power amplifiers, never choose low-power. Under normal circumstances, at least the rated output power of the amplifier must be more than twice the power of the speaker. Although the big horse-drawn car will cause unnecessary waste of power, the situation of the small horse-drawn car prevents the speaker from getting enough driving power, and the entire sound system cannot play the best sound effect.

 

The second is impedance matching. The output of the amplifier and the input impedance of the speaker should also be the same. Although there are some slight deviations between the two, it will not have a significant impact on the sound quality, but will only have an effect on the output power of the amplifier. In severe cases, the amplifier will be damaged. Therefore, it is better to choose the same as much as possible.

 

Finally, talk about the damping coefficient matching. The so-called damping is a measure of the internal resistance of the amplifier output stage to the speaker damping. If the damping coefficient is too high, the sound coming out of the speaker will be dry and not round; if it is low, the sound will tend to stick together. Therefore, when you configure the power amplifier, you should pay attention to the damping coefficient of the stone machine is controlled between 30 and 40, because the internal resistance of the amplifier is high, it must not exceed 10.
