I wonder if IsoAcoustics footers would work even better, or perhaps those footers on granite would be ideal. I would think just using a granite plate would compensate for a bouncy floor, but at the same time easily reflect vibrations back into the speaker, which you would not want.
Granite Bases for Vandersteen speakers
I had granite bases made made for my Quatros on Richards recommendation they weigh 120 lbs
The bases tightened up the bass mover it down even lower ,focused the midrange and add more depth to the soundstage you can check out the picture in virtual systems
Enjoy the Music
