The speaker is indeed a kind of equipment that is not simple to show problems, as the saying goes, be prepared, if you can do daily protection and maintenance in the process of using the speaker, at least you can postpone the use of the speaker life, so that you can use it more smoothly. In the use of the speaker, many problems are often not caused by the speaker itself. Problems such as dust, moisture and positioning will form problems of the speaker, and these problems should be paid attention to in ordinary use. Dust has always been the natural enemy of power amplifier, many power amplifier in the process of long-term use, often neglect the huge lethality of dust, but sooner or later there is a disaster.
Many friends will ask the speaker is the choice of closed planning, how can the dust enter the box? I have to say that this is actually a kind of incomplete knowledge. Although the speakers have selected sealed planning, some brands with independent subwoofer speakers, the connection line between the satellite box and the subwoofer is stuck on the foot of the box.
If a lot of dust enters here, it will form a smooth connection between the speaker line and the speaker, directly affecting the sound quality of the broadcast, which is also the work that many friends have encountered. Although the speaker is a sealed structure, its interior is not completely will not enter the dust, when there is dust in the box, the most difficult to clean is the speaker unit, a little attention will let the speaker burst, finishing time is the appropriate need to pay attention to.
