a distinguished
pedigree

11

KEF has always been the purist’s brand. 

Founder, Raymond Cooke, was an ex-BBC engineer whose
innovative first designs earned the respect of broadcast
professionals all over the world for their accuracy and
neutral balance. 

In 1961, he founded KEF to pursue a simple but elusive
ideal: to reproduce recordings so perfectly that they sound
indistinguishable from live performance. This same
perfectionism is what drives today’s engineers at KEF’s
research laboratories in the UK.

In any technology-driven organisation, perfectionism
means constant innovation.  From computer modelling
and the use of aerospace technologies to the development
of new cone materials, KEF has done more than any other
manufacturer to advance the state of the art. That’s why
the latest incarnation of the aptly named Reference Series
is as much of a benchmark today as the original was 30
years ago.  Just as the groundbreaking new Muon concept
sets unprecedented standards of audio fidelity. Created in
collaboration with Ross Lovegrove, these aluminium
sculptures exemplify KEF’s ambition to achieve perfect
acoustic transparency through radical design thinking,
obsessive attention to detail and engineering excellence.

This new Q Series is the latest expression of the KEF
ethos, and provides a source of lasting pleasure and pride
for the makers and owners alike.

Founder, Raymond Cooke, MBE.
