The idea works. How well is just a question of mass. More mass, more damping, less ringing, less cabinet/frame movement.
Build listening room in basement. Dig out, fill in whole floor with new reinforced concrete screed. Raise speakers each on three metal spikes calibrated to bring them to correct listening height. Choose your own metal to taste.
There. Screed is intimate with the earth's mass so you have infinite mass loading. To all intents and purposes.
I have the same set up for my record player, raised from the concrete floor on large stone and marble slabs.
By the way, if you choose to go stone or marble, don't mess about with 2 or 3 inch thickness. No way that's enough mass unless you cut them much larger than the speaker footprint - say 5 foot square.
Mass is a wonderful thing. It allows all your kit to perform to max without external or interdependent vibrations.
