Get a good stand like Atlantis Reference (4 pillar), very heavy even unfilled, then fill them with silica sand and or shot. Use the spikes. Then go to your hardware store and buy stick tack, same stuff as Audio sells but for about $2. One package usually does it. Put a small ball of the stuff on each corner of the stand then place the speaker on top and gently push down. Short of bolding it down to the floor this would be your best defense.

I am soliciting advice ... opinions even ... on what to do with my rig. My stand mounted B&W CDM-1SEs were almost the victim of a knock down over the weekend ... by my wife of all people. This started the 'this is a living room not a media room' diatribe. Insult to injury is the fact that our first child is on the way. I beg you for suggestions ... ideas tto make the CDMs more stable or a really nice floor stander that I can get into in the $1,000 - $1,500 used range. All opinions are welcome and appreciated.
