Every vital component is made in KEF factories under stringent quality control. The units are fitted with large super-power magnet systems built to close mechanical tolerances and fabricated in KEF workshops.\u003cbr\u003e\nEvery speaker Is acoustically compared with a laboratory maintained system to ensure strict control of production, consistency, reliability and sound quality.\u003cbr\u003e\nKEF users include many great musicians, recording engineers, and highly critical audiophiles in all parts of the world.
