Anyone try decoupling speakers from the room?

I wonder what Bobby P. would think of your setup. My guess is that he would be horrified.

I use Symposium Ultra platforms under my 3 way speakers (even though I have carpet over a concrete floor on grade). I prefer it to spikes. The bass is tighter and clearer and the midrange is more focused. Also worked better with my old Vandy 2CIs (with in this case Svelte platforms).

9rw,
The speakers are a product of a genius, I believe that by me trying a different approach is an attempt to make them more synergistic to my room and not any attempt at changing them. I use Bobby's bam and the speaker itself is not modified. It's too bad some are close-minded.

Concrete floor=spikes.
Suspended wood floor=decoupling.

A generalization, but probably true in most cases.

I have suspended wood floors under carpet and spiking sounds very bad vs. decoupling.

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.
