Humming capacitor?

  1. Hi, what can cause a capacitor to hum?
    My active speakers are producing a lot of hiss (tweeter) / low humming (bass speaker) and the cause seems to be a capacitor as it vibrates a little and makes some noise doing it. Is it because of ageing?
    Thanks.

  3. what you are hearing is 60 hz hum probably due to bad capacitors in your amp.
    proof: put your speakers on another system and see if it goes away. double check by putting proven speakers on your system.
