How such a sweet sound this is holy moly. 

Please remind me which Class´e amps replaced which Adcom amps.

So you can over damp virtually anything. The bearings are available in many od's the ones I use are 7 million per pound or just slightly less than a million per pound. Application dependent. The finished product is stiff..I dont bi wire. You can use Bondo type fiberglass to fill any hole which is stronger than the typical wooden box Tom

The bearings should not be to small because that will limit air space as well as limit motion. 
Motion is needed to dissapate resonant energy in the cable jacket or maybe in the wooden box you describe...there is such a thing as to much mass. We need to find a balance between mass damping and resonance control. Sand sucks and lead sucks the life and air away no matter where they are used. My material choices start with a table listing velocity of shear. Being a member of the Starsound panel we select brass and have those parts machined to our geometric designs snd applications. Geometry can be used to gather, steer and direct resonant energy out of a speaker and component. The larger and heavier the component is..the greater the energy level stored.
