How long is speakers' life span

　　The large items such as speakers also have to go through the assessment of service life. Generally, a set of sounds can be used for about 15 years, and the livelihood of love will be lengthened.

　　Daily maintenance method of speakers:

　　1. Dust -proof is the first place

　　Dust has always been a natural enemy of the amplifier and speakers. The dust that falls into the speaker horn will have a subtle effect on sound quality. Clean up the speakers at least once a week, try to keep the speaker from being disturbed by dust.

　　2. Do a good job of moisture -proof

　　Wet is a speaker horn invisible killer. The humid speaker will cause the horn's diaphragm to physical deterioration during the vibration process, thereby accelerating the aging of the horn film, which directly leads to a decline in sound quality.

　　The passive speaker is basically equipped with an external amplifier. The amplifier is the most afraid of instant current impact, and the current is easy to cause the power to be burned. Before turning on the sound source device, the speaker sound should be adjusted to the minimum, and the volume will be adjusted after the sound source equipment starts.
