Sorbathane under granite slabs for speaker bases?

Dill, so I should use something under the granite?

Thanks ghost,

Are you using spikes as well? I think I'm going to roll with just the granite slabs directly on the tile shelf w/spikes under the KEFs.

Thank so again for the replies everyone,

Does anyone know what Herbie’s soft fat and thin dots are made of? It seems there is a lot of advice here to avoid sorbathane but use his products. Wouldn’t they have a similar effect? I don’t mind supporting him at all I just want to make sure I take the best path. My KEFs did come with the spikes and the brass gold feet. I’ll try both the spikes and just the gold feet on granite to see what works best. I’m still wondering what/if anything I put between the granite and tile. I wish I didn’t have to hollow tile shelf but at this time I have to work with it.
