Does anyone use wood for vibration control?

Hi Geoff i just had a great listening and tuning session just now while commenting what i expreicned to Michael on what i did. 
Just to share what I did just now, I tuned the side walls and my floor by applying few pieces of wood beside the speaker stand and that brought out amazing image and better layering of my stage. I tensioned one of the bolts of my  front wall and that brought out the stage more forward towards my listening spot. 

Now since you are a man of science and seems to be an amazing physicist would you care to comment on what is happening to my setup and tuning ?

When you get to the place in your hobby that you start to realize the audio signal’s interacting with every thing around it a new hobby begins from that point on. Most people I see going down this new path usually go the dampening route for a while because the changes are so obvious. After a while though they start finding that they can’t play as many recordings as they once did. The system will sound very detailed and musical on some recordings but far less forgiving on others.

This is the exact observation I had during my early days in this hobby. Lucky me your methodes brought my system to another level and now implementing that same vibes to your speaker has brought me to very happy place indeed.
