29 KEF was founded in 1961 by an electrical engineer named Ra ymond Cooke in a Nissen Hut on the premises of a metal working operation called K ent Engineering & Foundry (hence KEF), on the banks of the River Medwa y , near Maidstone in K ent.
31 30 By 1973 the company was de veloping the concept of computer assisted ‘T otal System’ design, at a time when the world’ s v er y first 4-bit micropr ocessor was still in its infancy .
33 KEF’ s acclaimed Reference Series Under new ownership in 1992 KEF Audio f ound itself equipped with new ideas, ne w personalities and new pr oducts. But the same philosophies of solid engineering and innovation to pr ovide the finest quality product a vailable at its particular price-point remained firml y at the bed-rock.
35 The millennium ushered in a ne w era of groundbr eaking audio innovation. Among the most important was the launch of a new Refer ence Series - the forerunner of toda y’ s design - in 2002. This redefined the benchmark for high-end loudspeak ers by incorporating signature KEF technologies such as Uni-Q and the ‘pod’ concept.
