Speaker cabinet vibrations are complex and varied. Rick makes a good case for the cabinet vibrating like a balloon. As drivers pressurize the cabinet, air pressure causes the walls to flex outwards like a balloon or tire being filled with air. Then it rapidly depressurizes. These cycles cause the whole speaker, not just the baffle, not just the sides, but the whole thing to be expanding and contracting. This is in addition to the obvious forward and back motion caused by the drivers.
This may be one of the reasons cones and spikes work better than sitting directly on the floor. Cones and spikes go in corners, which are a lot more reinforced than the middle of the bottom, which is vibrating up and down, expanding and contracting.
None of this vibrating is anywhere near as simple as that. What we think of as back and forth, expanding/contracting or whatever, if we look closer there are waves riding upon waves. This is a lot of what Wilson and others are trying to address with their composite honeycombed unobtanium high tech materials.
Pods and Podiums simply allow all this complex motion to occur without exciting adjacent materials such as the floor. They work by allowing the speaker cabinet to dissipate its own energy without feeding into the floor, and equally important, without the floor energy feeding into the speaker.
However we explain it, the results speak for themselves.
