It works, too - http://campustechnology.com/articles/2013/12/19/cornell-researchers-develop-3d-printed-loudspeaker.aspx

Wonder what it sounds like?

Rubbish I should think...but impressive to produce something that works at all.

The materials used in loudspeakers have particular properties. A chassis might need to be rigid and inert. A cone may need to be stiff, light and have particular behaviour as it approaches the limits of its performance. Magnets again have properties that can be set by the heat treatment they receive. I do wonder whether it will ever be possible to incorporate these quite specific attributes in 'printed' items.
