If the frequency of middle and high frequency band is too weak, the timbre becomes dim and hazy; If the frequency of middle and high band is too strong, the sound will become dull. If the frequency of the middle and low frequency band is too weak, the sound will become empty, weak, soft; If the frequency of the middle and low band is too strong, the sound will become stiff and lose vitality. If the low frequency is too weak, the tone will become thin and pale; If the low frequency band is too strong, the sound will become muddy. The timbre characteristics of the four frequency bands are shown in the attached table.
