Having the woofer closer to the floor changes the floor bounce cancellation effect in the lower midrange/upper bass. Nearly all stand mounted or tall floorstanding speakers suffer from this problem. It thins out this musically important area which some people interpret as increased clarity/resolution. The Mapleshade stands don't eliminate the effect, but only changes it. Depending upon your speakers, your room, your musical tastes, etc. you may or may not like the changes.

I've read all the hype on these stands and even tried a low cost diy version and I have to say there is something going on with what Pierre has to say. Not to say he is right, but there is definitley a different sound with his low on the floor concept. Anyone actually using his stands and what are your thoughts? Thanks!
