Anthony left a 12"x12" piece of silicone sheet here last week and said I could do with it as I saw fit. I cut it into strips, and now have my Ref 3.5 speakers each sitting on 2, 12"x1.5" strips. It really made a nice improvement in the sound. Remember, my 3.5s are more like a 3.4s, as the base is not the current 3.5 production base. The production 3.5 has the silicone bonded to the bottom of a phenolic base, and the base on my speakers is just the maple of the 3.1. Anyway, I could bring the strips with me on 3/17 if you're interested.
