@malatu - I agree with others- about using 4 cones, but as stated you may need to "shim" one of them
However, should you want to try 3 cones there are a couple of approaches you can use but it depends on the weight distribution of your speakers.
"Generally" if the majority of the weight is at the front of the enclosure
- the single cone would be at the rear of the enclosure
- the two cones would be at the front, spaced as wide as you can get them
However, placing the two cones along one side of the speaker and the third cone in the center on the opposite side may provide sufficient stability.
If oyu would like to try the 3 cone method above I would recommend low profile cones and the surface on which the speaker stands should be hard.
I have three cones on my components and their position is very much dependent on where the bulk of the weight lies. Each component sits on a granite plinth
Something to try perhaps? :-)
