I let someone borrow my klipsch speakers and when they were returned they had a slight buzzing noise. They do this freestanding not connected to anything. does anyone know what the problem is?

You mean to say that just sitting there with nothing attached to them they buzz? Electrically, that's not possible.

Check for hornets or bees inside.
