ADAM Audio was founded in March 1999 in Berlin. Since then the company has been developing, manufacturing and distributing loudspeakers in the field of Professional Audio. The development of the X-ART (eXtended Accelerating Ribbon Technology) tweeter based on the 1960’s invention of the Air Motion Transformer by Oskar Heil was largely responsible for the company’s founding. Producing sound not with a piston-like diaphragm as is done in most of the loudspeakers that are on the market, but using a pleated diaphragm that is capable of moving the air 4 times faster than the folds themselves are moving was the appealing idea behind it all. The achieved results were intriguing and gave ample reason for moving forward.
