Well, they do reduce beamy treble, but they also reflect the signal back to the cone, causing distortion.
A 3" round piece of open pore foam glued to the grille cloth will absorb treble without reflections.
Another method is to use a larger piece of foam in front of the speaker with a 3" hole in the center. It will disperse the treble in a wide pattern.

I just tried the 3" foam, worked a peach! Its amazing how much difference it makes. The sound comes from all around the amp now.
Thank you for the tip. :D
