We had a topic about this a while ago. I decided to use my meter and check the EMFs around my new computer set-up. I was surprised how much one speaker gave off even when they were turned off so I decided to replace them. I had 2 older sets in the garage (no separate bass either, just 2 speakers).
One set gave off very little EMFs from the speakers themselves but the power module gave off a ton and decided it would be too close to my lower body. The other set gave off just as much from the transformer and also from one speaker.
So, my question is is there any computer speaker set out there that is relatively safe to use? The sound out of my Mac Mini is not something I can live with long term. I don't need or like bass just want a small 2 speaker set.
