IMy listening room's in my basement and I bought a pair of usher be20dmd's. These speakers weigh 200 lbs ea and the iron plinths that screw into them with 10 3'' metal screws weigh 85 lbs each so 285 per speaker
The dude that sold em attached coasters to the plinths so they could be slid on carpet, they looked like 4'' vinyl tiles. I peeled the tiles off and put the supplied spikes on and bass improved tenfold, in fact I doubt he would have sold them had he listened with spikes attached. Did raising the speakers 1'' off the floor tighten up the bass or was it decoupling the speakers by installing the spikes? I know it wasn't the weight. Yes the ushers used 3 spikes per side, as does my hegel and meridians.
