Hi A simple question. I have been using my floorstanders with RDC cone cups under each carpet spike. The floor is carpeted and the speakers are level but wobble front to back and side to side if touched. They feel solid but I am wondering whether this wobble is actually not such a good idea. I think I read somewhere that it is not good for speakers to move at volume as this can mess with the sound. I am not using the RDC cups to stop damage to the carpet so will get rid if the general feeling is that the speakers should have as good an anchor to the floor as possible. Thanks for any thoughts.
