Benchmark Technology

KEF has never been a me too. We create. And we never stop learning. The list of KEF patents and innovations is unequalled. Although the Uni-Q point source driver array is our most famous breakthrough, its just one of many. Theres the unique tangerine segmented waveguide. Cleverly stiffened and optimised aluminium domes. Sophisticated vented tweeters. The ingenious use of new materials to boost motor performance and power handling. Constrained layer damping. Acoustic Compliance Enhancement. The brilliant Z-flex surround - these and many others are what account for the reputation of KEFs multi-award winning drivers. No other manufacturer has done more to advance the state of the art - and no other range personifies KEFs passion for perfection more than The Reference.

A Class Apart

With six models - two elegant three-way floorstanders, a formidable three-way bookshelf speaker, two three-way centre channels and an awesome 1000-watt sub - The Reference range combines benchmark high fidelity with complete multichannel versatility. And as youd expect, they all exude the sense of sheer quality that comes from being hand built by KEFs master technicians in Maidstone, Kent.

Uni-Q driver array

At the heart of The Reference is a stunning new iteration of KEFs landmark innovation: the Uni-Q point source MF/HF driver array. With a state-of-the-art 25mm (1in.) vented aluminium dome tweeter at the exact acoustic centre of a highly sophisticated 125mm (5in.) midrange driver, both act as a single source that floods the listening space evenly with a flawless natural soundfield, no matter where you sit. Capturing all the nuances of the human voice, whether whispered, spoken or sung, it sounds as if the person were right there with you in the room.

Bass drivers

Clean, rich and articulate bass grounds your enjoyment of stereo or multi-channel sound, and like everything else about The Reference, KEFs new 165mm (6.5 inch) LF driver is in a class apart. With a massive vented magnet assembly and a large aluminium wire voice coil driving an exceptionally light, stiff and strong alloy cone, the dynamics and power handling are superb. Played loud or soft, in delicate passages or for full-on bass effects, the combination of advanced materials and clever engineering delivers deeply rewarding lows that blend seamlessly with Uni-Qs immaculate midrange and treble response.

Composite front baffle

The Reference drivers are set in a smooth, strikingly distinctive front baffle engineered to eliminate response anomalies caused by diffraction. Made from an exceptionally strong laminated aluminium/resin composite and secured via high-loss pads and high tensile bolts, it adds tremendous rigidity to the inert cabinet.

Flexible port technology

The Reference has innovative adjustable ports for fine-tuning the bass output to your personal taste and the room characteristics. The flexible port technology pioneered for the multi-award winning LS50 is used to reduce midrange port resonance, with the flare and profile of each port calculated by computational fluid dynamics to avoid turbulent air noise that might colour the sound.

Crossover design

KEF engineers computer-modelled the ideal crossover networks before exhaustively auditioning every high grade component, individually and together, to select those with the lowest distortion and the smoothest response. Perfectionism takes time, but the difference is plain to hear. Nothing is overlooked - Reference crossovers are even mounted on separate boards and decoupled from the cabinet walls to minimise vibration and crosstalk.

Cabinet design

Finished by hand in pair-matched wood veneers to complement the composite front baffle, the shape and bracing geometry of the cabinets are computer-optimised to minimise secondary radiation from the cabinet walls and distortion from standing waves. With constrained layer damping to absorb residual vibrations, theyre engineered to eliminate any panel resonance, stray reflections or box colouration effects that would compromise the purity of the sound. 

Plinths and stands

The Reference 3 and 5 are solidly grounded on a plinth and spike set developed with characteristic KEF attention to detail, with a spirit level built into the plinth and spike sets easily adjusted by neatly concealed screws. The bespoke stands for the Reference 1 have a discreet cable management channel to keep the cabling neatly out of sight. Provision is also made for bolting the speaker to the stand for maximum rigidity, and the upright has a vertical compartment which you can fill with your choice of inert material for greater stability and acoustic damping. The stands are finished in Satin Black.

Kent Engineering and Foundry Editions

When Raymond Cooke set out to perfect the reproduction of recorded sound in 1961, he set up his first research lab on the banks of the river Medway in the Garden of England in a wartime Nissen hut formerly occupied by Kent Engineering and Foundry. Hence the name: KEF. To celebrate KEFs unrivalled heritage of continuous innovation in the half century since, and the part that the legendary Reference Series has played over the last 40 years in consolidating KEFs reputation among serious audiophiles, weve commissioned two bespoke editions of the latest range. With two striking special finishes - Blue Ice White, hinting at the blue of the original KEF logo, and Copper Black Aluminium - the Kent Engineering & Foundry editions combine the latest Reference technology with an aesthetic that subtly evokes this rich pedigree.
