Experienced people have such experiences, and the same pair of KTV speakers will have different performances in different environments. (Change and decoration status of area size)

① Usually method: The balance on the power amplifier to modify (enhanced or weakened the high and low voices) disadvantages is that the frequency point of the disadvantage caused by the sound of the sound is difficult to consistent with the frequency point of the power amplifier equilibrium. The auditory hearing seems to be more balanced, but the frequency response characteristics are not smooth enough, making the layers worse, and the self -feelings are dissatisfied when singing.

② Good sound can be reduced as much as possible. Internal quality is improved, and multiple reflections in the box are reduced to make the sound pure.

③ Blocking different holes will have different sound effects. When the speaker is not too far from the back wall, roof, and corner of the corner (within 1 meter), its sound effects are more different.
