You know, Barry, I've always found the same to be true. I prefer isolation to coupling for loudspeakers.
Carpeted floors are what I'm most familiar with, since all of the houses I've ever lived it were carpeted. In that case, the carpeting and pad provide isolation. But I've also had a bunch of installations at customer sites - both home and commercial - on hardwood, tiled or concrete floors. In every case, I prefer to isolate the speaker with rubber or fabric (carpet) padding.
I know there are a ton of people that prefer "spikes" or other mechanisms to couple the speaker to the floor. But I've always had better success decoupling them, isolating the speaker cabinet from the floor.
