Typhonics Sound-dampening SP Tiles

I realize that what you are seeing here is what looks like some serious kick-butt speakers, but they, in fact, sound dampeners.

You ever seen those acoustical tiles on the walls of recording studios? Is is essentially what these are, and I suppose they can be used in the home to keep one room less louder than the other.

You can attach it to your wall with some double-stick tape, and they run about $54.
