cute, but imho
1.) their "push-push/pull-pull" (which I'll assume means in phase) system won't reduce vibrations given the way these are oriented
2.) I don't see a legit justification based on their description of the radiation pattern for how this is different from a small monopole bass enclosure with the same (or different) wide-ranger on top. It may, however, help in terms of putting the speaker closer to a rear wall, assuming that's an issue to begin with.
