magnetically shielded

There used to warnings that the speakers should be placed like 30 cm away from the monitor or such. Some speaker are advertised as magnetically shielded. I have Edifier 1000db. I don't know if these are magnetically shielded or not. There isn't much room on my computer setup table. Is it fine...

So for the last couple years I've been using Cyber Acoustic 2.1 speakers and they pick up radio signals. Normally its not an issue since I can't hear it at all when I have the volume at normal levels. I did look into a bit here and there and standard searches always said to use shielded cables...
