KEF Reference 4 Meta Centre Speaker

KEF Reference 4 Meta Centre Speaker

Detail remastered. An icon redefined for tomorrow.

The essential for any audiophile. Hand built by the masters who set the standard for audio quality, The Reference has been the benchmark for loudspeakers and sound reproduction. The Reference is an embodiment of KEF’s philosophy and the relentless pursuit of perfection. Now with Metamaterial Absorption Technology (MAT™).

The benchmark of centre loudspeakers

For movie lovers looking for total immersion, Reference 4 Meta is the last word in absolute quality. Featuring four bass drivers and 12th generation Uni-Q® driver array with MAT™, this centre speaker (can be used as Left-Centre-Right speaker) is a revelation for clarity, detail and emotional depth.

The benchmark of benchmarks

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.

Always innovating

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.

Designed, engineered and handcrafted in UK

Since 1961, we have been creating remarkable award-winning loudspeakers at our UK home in Maidstone, Kent. As our flagship HiFi speakers, The Reference is still being designed, engineered, and handcrafted in Maidstone today.
