Similar concept to Genelec's isolation platform (effectively, a rubber pad on which Genelec's active speakers sit). The key thing is to remove as much vibration and isolate the speaker as is possible. Have a look at sthe Steve Hoffman forum and search for Barry Diament's (legendary mastering engineer from Atlantic) thoughts and tips on how to do this too - then see if you've any spare bicycle tyre tubes kicking around. 😉
Neat looking proposition though.
EDIT: Welcome to the forum by the way!
