Adding a Base to Floorstanding Speakers


I use floor standing speakers on spikes on carpetted wooden floor.

I am thinking of adding a heavy concrete slab as a base for each speaker to reduce the floor vibration. Would this excercise be of any benefit to the overall speaker performence? Should the speakers still be on spikes if they are placed on concrete slabs? Any advice would be greatly appreciated.

I have slender floorstanders (Ruark Prologue Ones) that are prone to knockovers (with two big dogs and a toddler running around the house). I had Sound Anchors make me some custom spiked platforms that replaced the largely ineffective plinths that came with the speakers. They are mass-loaded, and triple the footprint size of the speakers. Knocking them over would now require a very deliberate effort on someone's part. The best part is the way they have decoupled the speakers from the sprung hardwood floors in my pier-and-beam house. They are very nice-looking (they look like the bases you see on the Aerial floorstanders on the soundanchors.com website) and cost me about $250, with a 6-week turnaround.
