Hi Don,
Your gear is nicer than mine, but I thought I'd share what I did with my Celestion S300's (floorstanders). My goal was to reduce "boominess", so I guess you could say I was after "decouplng". My speakers resonated too much when sitting on the floor.
First I cut a piece of plywood the size of the bottom of each speaker, and set the spikes on that. Didn't do anything for me.
Then I did the penny thing. I used a drill to make a little divot in the center of each penny to keep the spike centered. The coupling between the floor and the coin didn't seem to be a problem -- these speakers are heavy, and they come down hard on those sharp points! This gave me a noticeable improvement in sound.
What I have now is (don't laugh) 2 long pieces of stick-on felt on the bottom of each speaker. Sounds better than having the speakers on the floor, but not quite as good as the pennies. The big advantage is that I can slide the speakers around on the floor without scratching it. This is a big plus, when I really want to listen, I slide the speakers way out into the room. Also I get to tweak toe-in and separation. I could never leave them this way, too much traffic in the house. I gain more from the good speaker positioning than I lose.
Best of luck, I'm curious to hear what you find.
