Does anyone use wood for vibration control?

In the last hour I have put slivers of wood, up to 1/4" thick on the tops and bottoms of the springs. Much more girth and impact to the notes. Drums and cymbals are taking on more 3d shapes and the tone of the mid highs are rolling across the cymbals then come to the end of the cymbal and rolls into the air.

So to recap the springs on their own didn't do it with the other materials in the components. Then springs with the added tone from the slivers moves things a lot closer to real instruments sounds.

A couple more hours and I will go LTR Tuning Blocks, but the springs and wood is very listenable. I can move the position of each spring to get a different tonal transfer.

Pretty fun couple of days going back through these procedures again. Makes it fun to have a stereo to play with and hear the interaction of the entire space.

I added a thin slice of rubber on the bottom of the slivers under the spring and the sound went instantly dark and rubbery. Tried it on top, same thing. Not something I am hunting for so the rubber again sits on the sidelines. I also briefly put back in one of the players I added Geoff's NDM to and it was disaster. I can best describe this as a stage filled with black holes. I quickly put back in the non-treated CDP and in about 3 to 4 minutes the stage came back nice and full. I think the NDM can sit off to the side for a while as well, not really sure I'm going to go back that direction for a couple of reasons, meaning a couple other types of material that I like better on the tray. However the experiment with the NDM was not a complete wash. That's for another topic perhaps but after some further experimenting is done.

Ok, some more listening and I'll be back.

"I gotta believe that springs are gonna vibrate like hell."

As a matter of fact the Springs do vibrate more than any of the other shapes I have used. I'm not saying that as necessarily a bad thing just a true thing.

All one has to do to see evidence of the ability of a well-designed spring system to provide true isolation is to watch on You Tube the videos Max Townshend (a real mechanical engineer, if you care about such matters ;-) has made to promote his Seismic Pod products. He attaches a surface mount accelerometer to the outside wall of the enclosure of a floor-standing loudspeaker, and assaults the speaker enclosure with various forms of vibration, both loudspeaker generated and floor borne, both with and without the Seismic Pods installed.

Having seen the demonstration, the listener may then decide for him/herself whether or not he/she wants to prevent floor borne vibrations from reaching the speaker enclosure, and if he or she wants to evacuate driver-generated vibrations from the enclosure onto which they are mounted.
