Here are a few thoughts, for what there are worth.
IMHO the only vibrations which originate in a speaker that are 'necessary' to drain are those which by reason of construction and materiels creat a resonance at some particular frequency, if that resonance actually effects sound quality (some speakers are voiced to include resonances). In order to 'drain' the vibrations at any particular frequency (where the resonance occurs) wouldn't you have to have materiel which would be capable of passing vibrations in that frequency as opposed to having a similar resonance frequency which might then compound the problem? If that is correct how do you select the materiel used to connect the speaker and the floor?
What I think might actually be in play, which is not discussed much, is the benefit of isolating speakers from the floor. Again IMHO most of the vibrations which occur in the rooms and floors are the result of airborn loading from the speakers. When the speaker is fully coupled with the floor these vibrations are being fed back into the speaker which causes a change in perceived sound quality and may actually increase the degree of resonance of the speaker in its resonance frequency.
As I said, just some random thoughts..............
Just a few thoughts, I'm sure most of you have the answers and they are not revelant.
