That's a good observation that Jadem made about the horizontal displacement of energy in an air bladder type device.
As to bearing type devices, i think that they act as kind of a vertical coupler with a horizontal damping valve built in. That is, due to the mass forced down on the bearing, it pretty much will act as if the device is coupled to the support underneath it, at least in the vertical plane. If there is enough energy involved to displace the bearing, this energy would cause horizontal motion rather than vertical motion due to the mass loading effect.
In effect, the horizontal displacement would only come into play during severe situations, acting as kind of a "pressure relief valve". Obviously, i'm just babbling here as i've never studied this type of device or the principles that they are based on, so i could be completely off in left field on this one.
As to the comments about bubble wrap, i remember reading your first posts about this. I also remember Ric from EVS discussing using bubble wrap underneath his Millennium DAC's several years ago, so there has to be some validity to Jadem's results.
As to Greg's original question, see my response discussing combining mass loading / coupling / absorption in a random fashion in the other thread that discusses rack building, etc... For optimum results, you really need to do the math and look at the system as a whole. Without the math and everything taken into account, you're back into the "chaos theory" of system tweaks with anything being possible. Sean
