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.
