Jeff, by suppressing the transmission of 'noise', you are also suppressing the transfer of vibration and resonance. Therefore, any air-borne vibration or resonance inside your components, rack, and/or speakers have no exit path.
I'm relatively new to this, but even though you may still be using cones, you appear to still be applying damping and isolation techniques to the sharp part of the cone.
In essense, it appears that you are trying to combine the two major philosophies of handling vibration and resonance when in fact these two philosophies are almost diametrically opposed and one should be considered an oxymoron to the other. Like mixing light with darkness.
In essence you are still putting a cork in the vibration's only exit path and thus trapping those vibrations inside the unit. That component quickly reaches the point where the vibrations become congested like the 405 freeway in Los Angeles during rush hour traffice (at a standstill and getting worse).
But I believe a more accurate analogy would be the 405 freeway at rush hour completely congested with traffic at a standstill with every car having 4 passengers per car. And with every car at a standstill, every passenger of every car is running around the car doing the (foreign) fire drill. And in your application, if it can't exit from the cone, the resonance stays in cone and in the component resting on the cone.
The passengers are the microscopic vibrations running around like crazy but with nowhere to go. And that is what reaks havoc on the sonics at the micro- and even macro-dynamic levels.
To the best of my knowledge, one cannot suppress or dampen vibrations of this kind. One can only alter them or transfer them.
Have you ever been at a stop at a traffic light and some guy about 4 cars has his subwoofer blasting? You feel it in your chest and your inside rearview mirror is vibrating like crazy. You roll up the windows and it helps but just a little.
Yet your car is resting on what should be some fantastic suppressors or dampeners known as radial tires and air. So is the jerk's car blasting the subwoofer.
If only we could drive our cars around on Star Sound's Audio Points(TM). :)
I'm no expert, but this is what I've come to believe through my research and experience.
