I was just vacuuming my carpet, and the thought came across me that it might harm my speakers for some reason due to its magnetism. When I vacuum near my tv or computer, the picture stards to get grainy, 'snowy' and filled with static. Does this damage these components? Because just today, I was vacuuming within a few feets of my Paradigm Titans and CC170, and within inches of my PDR10. SO, can this cause any permanent damage? My CC170 says that it's magnetically shielded, but what about all my other components?
