It's the magnet in the subwoofer pulling the guns in the CRTs off track. 
  I don't think there's anything you can do about it except to move the 
subwoofer away from the monitors.  If the monitors' color doesn't then 
return to normal, try waving something a wand degausser across the 
screen.  I'm not sure where you can buy them anymore.  When I was a kid 
and I screwed up our TV by putting a magnet-mount CB antenna on top of 
it, I fixed it with a wand degausser from Radio Shack, but they don't 
seem to sell them anymore.  Dan's Data covers the subject in the letter 
"Painting with magnets!":

It's only a problem for CRTs.  If/when you upgrade to LCD monitors 
you'll be able to put your subwoofer back between them with no ill effects.

Good luck!
