Facts, I have facts !
Did a few more experiments :
1. Moved the speaker so it was horizontal and a couple of inches below the bottom of the TV. No colour fringing but the sound seemed a bit less "clear" than with the M2 on top.
2. Tried putting the M2 vertically on each side of the TV to see if there was color fringing. No fringing on the left side, and a tiny bit when the speaker was on the right side, although moving it ~1/2" away from the TV was enough to make the fringing go away.
I think this is something to do with the arrangement of the phosphor dots on the CRT. I guess it might also have something to do with the fact that I was using a solid blue screen as a reference, hope I didn't miss something by only having one gun active. Will have to try some tests with different images.
I haven't tried listening with the speaker beside the TV yet but will also give that a try over the weekend.
