How to solve the problem of noisy high pitched speakers in the audio system

When there is a sizzling noise from the high pitched speaker, it can be tested by replacing the high pitched speaker unit to see if it is a problem with the speaker itself, as some high pitched speakers may age over time. There is a problem with the tweeter itself, simply replace the horn. If not, check the audio cable for interference. If the audio cable is intertwined with other wires, it is easy to cause electromagnetic interference and thus generate noise. 

After checking all the previous ones, if there is still noise, it is necessary to replace the amplifier for testing. Sometimes, noise may occur due to the small capacity or poor quality of the power filter capacitor of the amplifier. At this point, the noise problem of the tweeter has basically been resolved.
