  • So i could write an entire book here about this topic as ive spent most of my life around audio.

    But the simple part is, even if its a 2 prong, you may still have a chassis ground on the metal casing you need to hook to an outlet plate screw or other ground.

    The other issue could just be your house wiring. Some houses are not wired correctly and may not have proper grounding so you are picking up noise there.

    The other issue is, cheapo pots (like volume controls) sometimes make noise when they are all the way off due to imperfect contacts being used in their build.

    Speaker wire is always unshielded.

    If you have a bunch of wires running parallel to 120v you’ll get noise. If you have lot of cables coiled up you’ll create an antenna and possibly pick up a radio station.

    What make and model are these speakers? Its very possible they have a crossover in them with bad capacitors.
