The German manufacturer ETON was founded in 1983 by Ulrich Ranke and since that time produces high grade loudspeakers for high-end manufacturers and private customers. The patented by him HEXACONE-diaphragms are best known throughout the world for their stiffness despite their low weight. This guarantees a unique and pure sound which has become a hallmark of the company ETON. Whoever intends to realise a true high-end-project has to take a closer look on the drivers from ETON. Ulrich Ranke sold Eton in 1991 to the German maker LPG and is now manufacturing with his sons Ceratec speakers in Germany.
