Some people like to use spikes. Their goal is to firmly "attach" the loudspeaker to the floor, using the weight of the cabinet to "nail" it to the floor by having such a small contact point. The idea is to make the cabinet as steady and immovable as possible.
Another approach goes exactly the opposite, isolating the speakers from the floor. Most use carpeting as you describe, or rubber feet. I prefer this method and always put rubber feet under my loudspeaker cabinets between them and any stands and place the stands on rubber mats or on carpets.
