Bose audio maintenance precautions:

1. Avoid use in harsh environments: various parts of the speaker such as wood veneer and paper cones , treble silk membrane, suspension, centering bracket, adhesive, voice coil, etc. are mostly sensitive to changes in temperature and humidity. If the temperature is too low or too high, it will affect the stability of the component. If the temperature is too low and less than 5 degrees Celsius, the overhang will easily become brittle and cause the overhang to break. If the temperature is greater than 40 degrees Celsius, the voice coil will overheat, which will cause sound deterioration.

2. Problems with the place of use: Any sound that is turned up to the loudest will have cracking and other phenomena, so the volume can be turned up to 8. The original power of this sound is 40W. If the average household It is more than enough for use in a space of 100 square meters. If you put it in a square or use it in a large classroom, its power will inevitably be unbearable.

3. First time use of newly purchased speakers: Some people advocate using loud volume to play loudly, but this is wrong. Only by slowly running in can the mechanical part (the vibration part is equivalent to the mechanical part) get the best performance. After a good running-in, crazy burning will not do any good to the sound. If the burning is not good, the voice coil may be deformed. Therefore, the flavor can only be obtained by simmering it slowly, otherwise it will easily cause problems such as sharp, hoarse, cracked, uneven sound, etc.
