Oem,
I place mine on the teak wood floor,and lay a carpet in front of the speakers.
My fried has wall to wall carpet and use the cerabase directly on the carpet,and the results are just as astounding.
3 or 4? I use 4 under each speaker,using the speaker screws to thread in the cerabase ,but you could experiment.the important thing is to make sure the cerabases are in contact with the speakers body....
