I guess it depends...
If the box of your sub isn't too good meaning it physically shakes, then its better to put something heavy on top of the sub then put the monitors on top of that, mass loading. If the sub is pretty sturdy then...
you don't have to worry too much about physical vibration but mechanical vibration might or might not be an issue. Some kind of conductive cone ought to be used in this case with the pointy side down.
Do both of physical and mechanical vibrations are an issue. I think you'd know if mechanical vibration is an issue of you don't actually see the monitor vibrating while it's on top of the sub yet the sound is not right. I would imagine the speakers would sound thin and unprecise if you have mechanical vibration problems.
If neither physical or mechanical vibration is an issue, just get the dots stuff that audiobugged is suggesting.
I read somewhere that cats are great decouplers.
