Muon

The MUON Story

MUON is a truly remarkable feat of sound-engineering and cutting-edge design. Rarely does one find such a sublime marriage of form, function and manufacturing integrity in any field. Individually crafted and carefully measured in KEF’s highly accurate anechoic chambers, each loudspeaker comes with a certificate showing its unique frequency response curve, signed by the skilled craftsman who made it in KEF’s Maidstone workshop.
