Pedrillo,
My previous listening room was over a garage, so the floor was suspended. Spiking the speakers to the floor increased the energy coupling and made it easier to drive the floor into its reasonant frequency (bad).
The solution was to put a piece of slate between the spikes and the carpet thus providing some decoupling. It improved the low end frequency response and reduced the noise levels in the garage (good).
This is a simple and easy thing to try, even if you substitute a piece of wood for the slate to hear for yourself what happens.
