First, pay special attention to whether there is resonance in the professional speaker cabinet. Generally, when the sound box with a thin box or a plastic shell is output at a large volume in the low frequency band below 200Hz, resonance will occur. The occurrence of cabinet resonance will seriously affect the sound quality of the output, so users should try to choose professional speakers with wooden shells when choosing professional speakers.
Second, pay attention to whether the chassis is anti-magnetic. Since the display is very sensitive to the surrounding magnetic field, if the magnetic field of the professional speaker box is large, the image on the screen will be affected, and even the life of the display will be reduced, so pay special attention when selecting.
Third, we must pay attention to the tightness of the professional speaker box. Because the better the sealing of professional speakers, the better the output sound quality. The airtightness check method is very simple. The user can put his hand outside the inverted hole of the speaker. If it feels that there is obvious air rushing out or sucking in, it means that the airtightness of the speaker is good.
Fourth, we must pay attention to whether the sound output of the professional speaker box is uniform. Since the sound source of multimedia music is mainly games and general music, the proportion of treble is large, and the proportion of bass is small.
Fifth, we must pay attention to the positioning ability of the sound field. The positioning ability of professional speakers is directly related to the live effect of users singing K.
Sixth, attention should be paid to the dynamic amplification limit of professional speakers in the frequency domain, that is, when the user turns up the volume and exceeds a certain limit, whether the speaker can still maintain a uniform and clear sound source signal amplification capability in the entire sound range.
