I fail to see how speakers which are connected to the floor "drive the room", whereas those which are isolated from the floor do not.
Guess the clue is in the word 'isolated' ?

How is the room "driven"? Through a set of spikes, or by the speakers' sound-emitting drivers?Guess the clue is in the word 'isolated' ?
I had a gawdawful room in my previous house, which I built from new - and so could specify exactly how things are. The one major flaw was the suspended wooden (carpeted) floor, which was completely porous to the mid-bass spectrum. It took me a while to work out why there was a 18dB suckout sharply centred on 80Hz. So, while there was plenty of low bass, mid bass and therefore gravitas, was completely missing from my replay. The bass had been going into the room below.I think both solid concrete and suspended wood floors can both work perfectly well. They have their pros and cons and you just have to work with the room you have to get the best out of it. Ultimately, a very solid room is easier to deal with as it's easier to tame a bright room than it is to lift a dull one.

I've become a flooring expert having just installed about 100 sqm of concrete floor. The layers were:
6 inches of compacted ballast
Damp membrane
4 inches of insulation board
Cabling and pipes
5 inches of screed (a form of rather dry concrete)
5mm flexible adhesive
Ditra mat
13 mm more flexible adhesive
6mm porcelain tiles (1m sq each)
If you can work out the acoustic properties of that lot, good luck.
My audio system is in the only room with a suspended floor, 1 inch of solid French oak. The room is acoustically treated and the floor has little impact, due to a large rug.
Most speakers probably get designed and tested in buildings with solid or poured concrete floors
Upside is that the ratios are good at 7 x 10 x 2 to 4.
