My theory. There are at least two issues to deal with. Draining vibration out of the speaker or isolating the speaker from the floor.
Each is helpful in it's own way. But which is better depends on everything in the system.
If a speaker is inert enough on it's own, then isolating the speaker is better. This is because there is a feedback loop that exists between the speaker and the rest of the system. Draining vibration into the floor will send more vibration into the equipment via the floor.
On the other hand eliminating cabinet vibration by draining it out may work better on a speaker that isn't very inert.
Both methods can and will make an improvement, but I've found that isolation nets a more musical presentation to the music.
Spikes drain away mostly low frequencies, so spikes on a suspended wooden floors may cause you to lose bass to the floor.
Cones and granite, especially BDR cones tend to reflect vibration back into the speaker. (I'm not saying the overall sound didn't improve with their use).
But the use of Aurios, Stillpoints, Darumas, Vibrapods, HAL Tenderfoots not only eliminated some cabinet vibration, but isolated the speaker from the floor.
The result was not only much more low level resolution, but the presentation and spacial cues sound more believable. BDR cones and other cones flatten the soundstage by comparison.
Putting Vibrapods on BDR "those things" or granite made the use of BDR and granite more musical.
(Caveat: I'm a Stillpoints & Daruma dealer, but utilize all the above mentioned products when appropriate)
