magnetic shielding?? (1 Viewer)

[PeterK]

Is there a way to shield a speaker from the outside? You see My back left speaker will be placed on a shelf deely right above my computer monitor. I just put it there now, and noticed some serious discolouration in the monitor. so that is currently not going to work. I could put the speaker somewhere else but I'd rather not. So is there anything I can do to shield the monitor from the speaker? (Place a sheet of metal under the speaker, encase it in concrete, use some sort of forcefield etc.)

thanks

A sheet of galvanized steel should work. Drop by your local hardware store, they should have it. Ask them about force fields too, just for comparison. The amount of concrete you'd need might be just a bit too heavy...

That might slightly perturb the field but it won't block it. Move the speaker.

It depends on the speaker and how strong the field is. I read that in a home audio book, I haven't actually tried it, and I wouldn't expect it to block 100% of magnetic effect with a larger magnet. The best solutions would be to move the speaker, buy shielded speakers or get an LCD monitor.

Well try an experiment John. Take a piece of galvanized steel or just about any other metal for that matter. On one side place a sheet of white paper and some metal filings. On the other side, pass a magnet back and forth and observe what happens.

Ok, I moved both my rear speakers back even farther so now the left one doesn't affect the monitor. It still sounds perfectly fine to me. Just to let you all know, the lid of a filing cabinet does nothing to block the magnet from the monitor. (that was about the only sheet of metal I had in the house :b)
