How do you shield a Center speaker?


I have a center speaker that has no shielding. Any time I get too close to my 36" Analog TV it affects the color. I have to keep it at a distance. Can anyone recommend a way to shield it so that I can move it closer?

OK... Im real curious... what kind of jankey-assed center channel isnt shielded?

Man that sucks!

I have a thread out recently about shielding, you might want to check it out, somone gave me a trail on a company that sells stuff to shield the speaker.
You shield it by not letting it read trashy novels, by being careful about the music you play on it and by really limiting what it sees on TV.
I have seen those "bucking magnets" and I wonder how they affect the performance of the driver you put them on. I would prefer the shielding approach.
