no problem there. (I use some MDF boards to raise my 125 lb. Plasma above my center which just lays on the cabinet top.)
The center speaker does not have much bass content anyway, which is where most cabinet vibration would come from.
As for the weight, it is no problem.
(if you are using felt be sure it does not have a tendency to slade right off the smooth surface of the speaker!!! and trash your TV.
