Came across these the other day.
Diatone is an OEM speaker manufacturer owned by Mitsubishi. They produced some very interesting and quite high end designs. Many of which never left the shores of Japan.

There is a pair of the D-80s in the London nightclub The Fridge. It is quite apt, as the cabinets are easily the size of most domestic fridge freezers. What they lack in subtlety, they more than make up with extreme presence.:eek::eek:
