What methods are there to avoid damaging speakers?

A major reason for speaker treble damage is that the amplifier's power is too low, not too high. The signal sent by the amplifier is a clipped signal, which damages the speakers. Therefore, when equipping speakers, you must develop a proper understanding and apply the "big horse pulls small cart" principle to prevent the amplifier from sending clipped signals and damaging the midrange and treble speaker assemblies.

When designing a speaker system, you should adjust the amplifier and speaker performance according to the above criteria. In practice, you should use the equipment reasonably at each stage to protect the equipment and maximize the performance of the speaker system. When adjusting the volume, many users set the power amplifier attenuator to -6 dB, -10 dB, that is, 70% to 80% of the volume waveform, or even to the normal position, and rely on increasing the mixer input to achieve a suitable volume.

It's a mistake to think that the speakers are safe if the amplifier has a headroom. The amplifier's attenuation knob attenuates the input signal. If the amplifier's input is attenuated by 6 dB, this means the mixer or preamplifier must output 6 dB more to maintain the same volume. The voltage must be doubled, and the input headroom, commonly known as "headroom," is halved.

If a strong signal suddenly occurs at this moment, the mixer output will be overloaded 6 dB too early, resulting in a clipped wave. Although the amplifier isn't overloaded, the input is a clipped wave, and the treble is too heavy. Not only will the treble be distorted, but it may also cause the treble tone assembly to burn out.
