Book of Music has released some very uniquely styled speakers termed the Teti Extreme Loudspeakers. These speakers don't come with your conventional enclosure system- the two towers are built on open frameworks allowing the drivers to work freely.
Truthfully, they show a striking resemblance to that revolving skyscraper built within the city of Dubai. Whether they revolve or not we haven't a clue. Designed in Italy, these speakers are up for only $20,000 on the manufacturers website.
