They are not speakers in real life, its commercials that use speakers in them, like drawings or animations. But the speakers don't exurt forward and back. They just get bigger and small in daimeter. You must have seen this before, its everywhere. Theres a rogers commercial with a woofer, and your looking at it head on, and you can see the surround moving as if you were looking from the side. another one is a walmart commercial and its a concert(trying ot be hip) and speakers pop out of the ground, and get bigger and smaller in daimater, they don't exurt forward and backward.
