Tony knocks them dead at the CES show, note the US sell price of the 1800 Reference!

Stereophile Robert Deutsch

A ribbon hybrid loudspeaker boasting an extremely high efficiency specification of 95dB. This is achieved while only using 25% of the power used to create the same volume as our standard models. These high efficiency levels are achieved with the use of special "rare earth" magnets, which help form the main part of the engine that produces the sound. These magnets are so powerful, they have to be freighted by sea as the magnetism interferes with delicate airline instruments. Tony has shown us that if you put them on a fridge one cannot actually remove them.
