Have you tried to replace the spikes under your speakers, and replace them by footers ? I find a better unity in the music from my speakers, and beefy sound, and more natural music.
mikedeu, see the comment from edstrelow, try with sorbotan or other damping thing to make tests, yes there are many different type of speakers and floor. You have to try and make tests, it is not great expenses
