coupling monitors to a stand

As above, Blu-tak or similar, available at most office supply stores. It will hold the speakers very securely, no worries about them getting knocked off, is an excellent coupler and damper, and is removable and reusable with no permanent damage to speaker or stands.

They're making an interesting news product for
this application.

You might want to try some "servo tape" , a thin rubbery double sided tape that holds well and is easily removed if needed. It can be found at any hobby shop that sells radio controlled planes or cars. I use it to keep my center channel from moving around on top of my TV and to keep my rear speakers on their stands.

NO RUBBER! You do not want to absorb anything. Transference is the deal. Getting you guys to think along this new science of resonance transference is going to take some work. Audiopoints will deliver. Now if you're into something a bit more costly, but amazing, talk to Robert about their new speaker support systems. I have owned mine for a week and, still, cannot believe the difference it's making in my system. I cannot overstate the importance of a good speaker stand. It is as important a component as the others. I'm going to do a little review about these stands, soon. Nix the blue tak. ( I know everyone uses this stuff. Another resonance absorber-) Anything that absorbs sound is a negative. Your stands are probably filled with sand or some dampening stuff. Right? Again, no good. I know everyone and their mother does it, but you want those resonances to go to the floor. That's where they belong.
