Professional stage sound and power amplifier impedance matching: 

The rated output impedance of the power amplifier shall be consistent with the rated impedance of the speaker box. At this time, the power amplifier is in the best design load line state, so the maximum non-distortion power can be given. If the rated impedance of the speaker is greater than the rated output impedance of the power amplifier, the actual output power of the power amplifier will be less than the rated output power, which will lead to insufficient sound and low volume. If the rated impedance of the speaker is less than the rated output impedance of the power amplifier, the actual power will increase, but the volume may be distorted due to the impedance mismatch. The sound system can work, but the power amplifier has the danger of overload, so the power amplifier requires perfect overcurrent protection measures to solve, and the impedance matching requirements for the electronic tube power amplifier are more strict. Power amplifier and speaker to fit, impedance match is the most important. The speaker is the main load body of the power amplifier, and the nominal (or rated) impedance of the speaker should be equal or similar to the rated output impedance of the power amplifier.
