Product Description

THE REFERENCE: the standard by which others are judged, and to which they aspire.

The perfect reproduction of recorded sound is what KEF’s legendary Reference Series has always stood for. And after 40 years of continuous development, the Reference has earned its name as the yardstick of high-end acoustic engineering.

If you’re a perfectionist when it comes to enjoying movies or music, it’s the one name that towers above the rest.

The Reference. It speaks for itself.

Clean, rich and articulate bass grounds your enjoyment of stereo or multi-channel sound, and like everything else about The Reference, KEF’s 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-Q’s immaculate midrange and treble response.
Detailed OverviewThe 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.
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.
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. 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, they’re engineered to eliminate any panel resonance, stray reflections or box colouration effects that would compromise the purity of the sound.
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.

Same DNA, more modest dimensions – and the same uncanny ability to generate an intricate, totally natural-sounding 3D soundstage. The two 165mm (6.5 inch) bass drivers are positioned perfectly above and below KEF’s latest 125mm (5 inch) MF/HF Uni-Q driver array in a D’Appolito configuration. Fidelity across the midrange and treble is outstanding, and the transitions imperceptible. And with Uni-Q’s broad inclusive dispersion, everyone in the room can enjoy the same rich, spatially precise acoustic imagery without being restricted to a narrow sweet spot. As well as putting you right at the heart of the original performance, it gives you the soul.
