“They create a soundstage effortlessly disengaged from the boxes that are producing it… On vocal tracks especially, the KEF REFERENCE 5s seemed to get out of the way completely and let the singer’s performance become as intimate and heartrending as you could wish… This is clearly an outstanding product.”
– Hi-Fi News & Record Review – Outstanding Product

“…its above‐average sensitivity, excellent bass extension and handsome appearance earns the KEF Reference 5 EISA’s High‐End Audio accolade.”



For over 40 years KEF’s flagship range has been distinguished by the name ‘Reference’ – an exercise in high quality engineering brought bang up-to-date for 2014 with the launch of five new Reference class loudspeakers. Available in Piano Black, Satin American Walnut and Luxury Gloss Rosewood finishes, the 1.35m tall KEF Reference 5 stands proud as the flagship of the range. The combination of four newly-designed 6.5-inch bass drivers, with gently contoured aluminum cones designed to complement the Uni-Q point source array, deliver a deeply impressive and realistic sound.

KEF-Reference 5-2

Magnificent is the only word. KEF’s passion for perfection embodied in a tall three-way floorstander that aligns four powerful, extremely linear 165mm (6.5 inch) bass drivers – two above and two below KEF’s latest 125mm (5 inch) MF/HF Uni-Q array, with the sensational new 25mm (1 inch) vented aluminium dome tweeter at the acoustic centre. Lows are reproduced with consummate agility and control, fluidly integrating with the Uni-Q output to create an all-enveloping soundfield of spine-tingling accuracy and depth. The KEF Reference 5’s distinctive front baffle is made from laminated aluminium and resin composite which is formed in extreme temperature and pressure to add rigidity to the cabinet structure and providing acoustic damping.

For music or film, the KEF Reference 5 reveals subtleties you’d never noticed while gripping your emotions with the full power of the performance.

About KEF

The company was founded in 1961 by Raymond Cooke OBE (1925–1995) and was initially headquartered in a Nissen Hut on the premises of Kent Engineering & Foundry (from where the name KEF is derived) – a metal-working company on the banks of the River Medway, near Maidstone in Kent. KEF’s ethos has always been based on the continuing quest to find new and better ways of reproducing sound. Since the company’s establishment, KEF has maintained a flair for unusual and controversial speaker engineering, design and material use. KEF has always driven innovation in sound with examples including its iconic ‘egg’, Muon and Blade speakers. KEF is a member of Gold Peak Group and its products are available in more than 60 countries. In 2011, KEF celebrated its 50th anniversary and now the company continues its commitment to building on its strong heritage.
