I had always thought that putting stand mounts on the floor was a bad idea. However, I know Pierre and he does some very good things so this fall I bought some ultra bedrocks on Audiogon. I was wrong, its not a bad idea, its a REALLY BAD idea, about 5 minutes was all I could stand of my Spendor speakers on them compared to Pierre's Quadrapier stands I usually use. Totally different sound balance, all bass, no treble. The good part was that I sold them to someone with large floor standers and they worked well for him. There may be some rooms in which this works but it didn't in mine.
