Can humming ruin a sub or speaker?

[cameron paterson]

I was wondering if a sub or speaker can be ruined because of loud hum? I know you can't hear it when you turn the volume up but can it still hurt your sub or speaker?

As humming is the result of a underlaying problem it's not good and the problem needs to be found and addressed.

The most common cause is a grounding issue somewhere. Failing that you have a defective product somewhere.
