I guess the usual scenario is the spikes are for carpeted floors, to let them anchor to something solid, and the rubber feet for all harder materials. I use the rubber feet on a carpeted floor, mostly for stability reasons. I find the spikes make the speakers a little less stable and I have kids in the room alot.
