couple or de-couple

Decouple so that the speaker cabinet resonance does not get transferred to the floor / structure and muddy up the sound.

I can't think of even one reason to couple your speakers to the floor. However, to de-couple them would offer multiple benefits since you're not transferring any energy or resonances.

IOW, it's a concrete floor with particle board sub-floor below the carpet? You still want to decouple the speakers.

If it's these speakers, I really don't think there are any gains to be had by adding some material between their base and the carpet.

Dense foam like these. They're not cheap but there is a cheaper method which is what I did. I went to a sporting goods store and bought a bag of these, then layered them to about 1.5 to 2" thick with contact cement. Then I cut them with utility knife to the size I want.

The rubber feet (assuming that's what I see in the pic) would decouple the speaker from the floor. If they have spikes, then replace them w/ rubber feet and you'll be golden.

I like to use the firm rubber mats, like yago mats or those temporary work mats shaped like jigzaw puzzle pieces they sell at construction supply stores (Home Depot, etc)

I took some pieces of those pads designed for furniture moving and put them under mine. These are the exact ones I used...there's a bijillion different designs for these things but only one I've found with a type of rubberized polymer backing (I think) instead of plastic.

My Monitor Audios have a similar base. I didn't use the spikes, nor did I screw in the rubber feet, I just set the flat plastic base directly on the carpeting.
My studio monitors (Tannoys) I've set on "woven" rubber mats that are sold as shelf lining, very cheep and about 3/32" thick.

one good question is does the floor have any movement. I was at a dance studio and the spring loaded floor for dance or gymnastics would not be very good because coupling the speaker to that floor would add a resonance to the speakers output. Good thing the speakers we placed on the Dance floor were 150 pounds and did not move very much. Yours might be a different story.

If the speakers were decoupled from the floor, the floor's stability wouldn't matter.
