No, you're not looking at a shrine to d12 dice. This wacky dodecahedral speaker (meaning it has twelve faces) is actually a tool used in the Kettering University acoustics lab in Michigan. So what's it do?
It's used to test the acoustics of large rooms because it produces omnidirectional sound.
But before you write the idea off as silly and unpractical, you might want to know the advantages of a "round" sound. Clearly the omnidirectional sound will give you a richer and just all around sexier sound than a traditional speaker system. But there's another advantage to having pairs of opposing speakers on the same axis: dodecahedral speaker systems have very low vibration, making them ideal for apartments with paper-thin walls and floors.
But dodecahedral speakers are priiii-cey. Expect to shell out more than $3000 for a pair.
