    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™).

    Total attention to detail

    Every speaker in The Reference range exudes the sense of sheer quality that comes from being hand-built by KEF’s master craftsmen in Maidstone, Kent, UK. They are designed to be acoustically exceptional, attractive to look at, and each speaker is meticulously built to KEF’s exceptional standards.

    Reference quality bass

    The Reference’s 165mm (6.5 inch) low frequency driver perfectly complements the new 12th generation Uni-Q® driver array. Smart engineering and meticulous attention to detail enables the bass to blend seamlessly with the immaculate midrange and treble.

    Engineered to be flexible

    The Reference speakers are welcomingly undemanding in terms of positioning and are easy to fine-tune for your listening area by using KEF’s innovative Flexible Port Technology.

    The smallest details, revealed

    Shadow Flare drastically reduces harmful cabinet diffraction, allowing Uni-Q® to work at its highest level. A precision-designed surface extends the waveguide effect of Uni-Q® for improved clarity, particularly when it comes to the subtle nuances of plucked strings and other percussive sounds.

    Computer-modelled cabinet

    The Reference’s cabinets are designed using finite element analysis to determine the ideal shape and bracing geometry to minimise secondary radiation. Constrained Layer Damping is then applied to turn what little vibration is left into heat.

    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, handcrafted in Maidstone, UK

    Since 1961, we have been creating remarkable award-winning loudspeakers at our UK home in Maidstone, Kent. As our high-end speakers, The Reference is still designed, engineered, and hand-built in Maidstone today.

    Finished to Perfection

    The expertly engineered cabinets are finished in a sumptuous high-gloss or richly detailed, pair-matched wood veneer to complement the strikingly distinctive front baffle. Five finishes are available, a combination of three cabinet finishes and five drive unit colours: Satin Walnut/Silver, High-Gloss Black/Copper, High-Gloss Black/Grey, High-Gloss White/Blue, and High-Gloss White/Champagne.
