The dodecahedra speaker is being developed at the University of Sao Paulo in Brazil. The speaker has 12 sides, each covering 360 degrees of sound space in the room. The listener can move around the room and hear sound coming from any direction and any angle. One speaker might be able to replace a set of speakers for front, back and rear setups, effectively saving on total costs, according to the commentary at Coolest Gadgets.
The speakers are an interesting concept, but I wonder how and where you would mount them? Wouldn’t placing them on a table or a wall effectively cover up some of the sides? And how would you suspend it in the middle of a room without bumping into it?
