It makes sense to couple speakers to a solid slab, and isolate them from a resonate floor. Every situation is a bit different.
Spikes through the carpet to a concrete floor made a pretty notable improvement with several different speakers in my old room. Now that I have a carpeted plywood floor with joists under it, I’m hearing more floor resonance, and need to experiment with isolation or even shoring up the joists underneath.
