Isolating speakers is something that seems counterintuitive to me. You want the cones (or membrane) - especially bass cones, to be able to reverberate very quickly. This means the cones have to change their direction of travel very quickly. The best way to do that is for the cones to be connected to a rigid cabinet that in turn is solidly anchored to the floor. Hence most speaker companies provide spiked feet for carpet use. I know speaker cabinets are rigid more for avoiding resonance than anything else, but the need for spikes tells me speaker companies have found their products to perform better if they do not move with respect to the floor in any way. Isolation by definition needs to provide the means to blunt the initial impulse of the sound wave either impinging on (or being launched from) your audio component.

In thinking it through with the concepts I'm familiar with, perhaps Stillpoints and other isolation accessories improve the higher frequency tones and retract ever so slightly from the bass tones when used with speakers. The reason I think that is because higher frequency drivers move much faster by definition than lower frequency drivers. Given the relative weights of these drivers with respect to the cabinets in which they're mounted, the isolation of the cabinet from the floor may lessen cabinet resonances for the higher frequency drivers. The bass drivers on the other hand may experience subtle doppler effects that detract from their ability to provide as defined of a tone compared to a cabinet that does not move from the floor - however slight this movement and affect is.

That said, this is all conjecture on my part. I know my fellow audiophiles here have good ears and I believe in the sonic benefits being reported. So that leaves me no choice but to acquire some and hear for myself with my own speakers!
Interesting thoughts; FWIW, my most expensive speakers did not even come with spikes, SF Aida's and TAD R1's
