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.

Well, I have a thoery that works for me. How you implement it is up to you.

1. Minimize surface area contact with floor, furniture, etc.
2. Minimize opportunity for speaker to move, often by adding mass.

The reactive force of the woofer motor can cause enough motion to distort the sound, or vibrate against the floor, Minimize that by any means necessary.
