What should be under my speakers?


I have Sonus Faber Grand Piano Home speakers in a 20' x 17' room with wood floors. The speakers have spike feet, and each one is sitting on a 1 inch thick, 12" x 12" slab of granite. Each piece of granite has a square piece of carpeting under it, as a further buffer. I know I probably could figure this out with a lot of experimentation, but what impact is the carpet likely having on sound quality? Would it be better (Subjective, I know) to have the granite slabs sitting directly on the wood floors? How would the sound change if I ditched BOTH the carpet and the granite? I would like to maximize bass impact, because these speakers are a bit thin in that regard. Thanks.

Time warp..Just a few years back the mere written word Audiopoint, Sistrum, coupled, resonance transfer, those words those terms were beaten up on these pages. So now with a little temperance from all involved, myself included those once riddled words are a now apparently a respectable thing. Cool! Tom

I can tell you without an audible doubt with my ears and two other pairs in audience that tighter coupling is more benefical than that provided by leveling. Unless you use additional added shim or shims of the same material you will loose coupling integrity with any leveling system I have encountered. The benefits of this maximum contact are better bass weight and midbass speed as well as greater image resolution. The last statement of vision would make you think my speaker was precisely level when in fact it was not, it was however precisely coupled to all surfaces. Tom
