I would like to know the exact specs of the floor.
It's easy to say that a floor is not a problem but I would like to see calculations. I would even suggest a test; I have seen industrial floors of concrete designed to suspend the weight of forklifttrucks resonate like a pitchfork at somewhere around 1 kHz when high power tweeters where in endurance test.
If you have a space under the floor the effect of dampening by sand (which by itself might be overvalued) is not there, making things worse.

And you have to understand isolation is a matter of balances; weak spots define your total isolation.
