RF with speaker and light
In my shop I have some static in the speaker for my radio which the receiver is in another room. It only does it when I turn on the lights in the room with the speaker in it. I do have a fluorescent light (twin t8's)that is about 2ft away from the speaker, the light is about a year or two old. I removed the bulbs from this light and the static seems to go away. Moving the light is not really an option. I can move the speaker if I have to(there are other fluorescents around the room), but would rather put a device on the speaker to stop the rf if it exists.

Twisted pair or shielded (or both) can help eliminate the noise as well. A for sure method would be to put the wire in grounded metal conduit back to the receiver.
