(Because cotton is a soft and elastic cotton shape, sometimes the pressure will be thin, but the expansion will appear to be too thick, it is inevitable that there will be some error, the size is only a reference, the actual is subject to);
Compared with the white sound-absorbing cotton, the black cotton has a much thicker bass effect, and the filling method is troublesome. It can be fixed by glue or mat on the wall of the box, and the middle of the box is left empty;

The above data is the best data for personal experience, so it is for reference only, the actual customer can also calculate by himself. In general, the filling volume of sound-absorbing cotton is 30-70% of the volume; how many problems can be debugged mainly, that is, when the bass is ambiguous and smeared It is necessary to install more points, but excessive excess of sound-absorbing cotton will also reduce the amount of bass.
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.
