That one is basically an unrealistically high powered subwofer with side speakers.

The pushing thing is possible though. My brother and i made a bass cannon. It has enough force to knock a person off their feet, and break glass. Not out of frequency, but sheer pressure. The one in his trumpet is just way to small to do that though. The one we have is almost a foot and a half in diameter.
