Generally speaking, human voice is sensitive to low and medium frequency sound below 800Hz, and the sensitivity will decrease with the increase of acoustic frequency. In order to control the frequency division distortion in the human ear is not easy to detect and the power is generally very small on the frequency band, so the high frequency division point is usually set at about 2.5KHz.
In other words, a 2.0 speaker can focus more on the mid-range, which is where the human voice is most abundant, which is why the playback of the human voice on a 2.0 speaker is relatively more pleasant.
In addition, if want to enhance the sound quality of sound box, it is ok to improve the quality of medium frequency unit with concentrated strength, also reduced the difficulty that manufacturer raises sound box quality .
