Sorbathane under granite slabs for speaker bases?


I’m getting two 12"x12" granite slabs to use as bases under my KEF Reference Model 2s via spikes. They will be sitting on a 5" high hollow tile shelf. Would using thin (.25") 70 duro sorbathane under the slabs help in isolating the speakers or will it possibly negatively impact the sound?

Thanks for any input.

At one time, I had a pair of floor standing speakers on a 1 inch thick slab of black granite.  It not only tightened up the bass, but removed a slight smear in the midrange.  I placed them directly on the carpet with the speakers with spikes installed on top.  I used the cups for the spikes to fit into.
