Product Description:
The speaker sound absorbing cotton is installed in the speaker to absorb the standing wave from the low frequency lead of the box. The standing wave is often the tail of the bass in the speaker, that is, the bass has a smear after the drum is ejected. To make low-frequency noise. The general manufacturer produces the speaker at the cost. This sound-absorbing cotton is saved, or it is rarely used. After the sound-absorbing cotton is installed, the bass is clear and powerful, and the sound-absorbing cotton is installed in the box. It is to narrow the space, but the actual acoustic propagation is to make the space larger. The sound of a box of sound-absorbing cotton should be mainly based on debugging, that is, the bass should be loaded with more points when the bass is smeared, but the excessive amount of sound-absorbing cotton is also excessive. Will reduce the amount of low volume.
