Stone slabs under speakers? (1 Viewer)

[JamesCB]

I just posted this in another well-known forum. Figured I'd get some responses (experienced) from here.

I firmly beleive all loudspeakers should be spiked or otherwise stabilized to prevent any movement of the cabinet while operating. I have heard of many (audiophiles mostly) who put a stone slab under their speakers (usually floorstanding). And usually with the spikes on top of the stone. What confuses me is when this is done on a carpeted floor it seems as though you would get a rocking effect. A flat stone would have to be VERY heavy to completely compress the carpet. Could someone please explain the concept of the stone slab? I am open to discussion and willing to give it a try if it seems worth while.

By the way, I'm just talking about the front L & R.

If the stone base is properly shimed it will not rock. The whole idea of a stone base is to isolate speaker vibration from wooden floors. I think most bookshelves do not produce enough energy to travel through well built, sand/shot filled speaker stands, but floor standers may benifit greatly.

This is very strange as I have been thinking about this for the past few days myself! I am going to look at a place down the road tomorrow that sells all kinds of stone. Hopefully they will have some black granite.
