Since 1973, The Reference has continually set the benchmark for loudspeakers and sound reproduction. Pioneering the use of digital technologies to achieve the highest audio accuracy, every pair can be matched within 0.5dB to the laboratory-maintained reference standard.
Since the first Reference speaker, KEF engineers have continued to innovate using what is possible with The Reference. Ground-breaking in its first incarnation, each subsequent iteration of The Reference has added to the world’s knowledge of the science of acoustics.
