Are there polystyrene beads in the Framework speakers?

Most laptop speakers are mediocre at best and many people seem to complain about the framework speakers.
I know part of it is because they are down firing.

In the smartphone industry the manufacturers are using polystyrene beads to make the speakers louder and sound deeper.

I am not sure how common that is in the laptop space.
Does anyone know if the Framework speakers are already using polystyrene beads in their speakers?
If not, that could be a possible solution for rev2 speakers?
I mean if you compare the size of the framework speakers to those of a smartphone, there should be massive potential.
