Impedance matching of array speaker system: 

when the impedance does not match, may cause change for the damping coefficient of the amplifier. The damping coefficient of the power amplifier is the ratio of the power load resistance value (mainly the speaker impedance value) to the power amplifier output internal resistance. When the impedance value of the speaker changes, the damping coefficient of the power amplifier can change. If the damping coefficient becomes too small, the low frequency characteristics of the speaker, the output sound pressure frequency characteristics, the high harmonic distortion characteristics will become bad, the output audio (especially low audio) bloated and cloudy, accompanied by innocence. If the damping coefficient is too large, it will weaken the low frequency sense, dry sound, not rich, but this situation is rare, and the actual replay effect is not affected.
