Testimonials

 

““Whoa! Those speakers look cool!”  How many hi-fi components earn that sort of remark from an audiophile’s spouse? But that’s what my wife said when she walked in, glanced at the newly arrived review samples of KEF’s Reference 1 loudspeaker — and did a double take…

“Surprisingly, the Reference 1s’ ability to play crazy loud while remaining completely in control was also valuable with simpler, sparer music, such as Adam Cohen’s We Go Home (16/44.1 FLAC, Rezolute Music)… I ended up playing the entire album through the Reference 1s, and at higher overall volumes in my room than Cohen himself used when I saw him in concert in a small theater last November. Who says you can’t get lifelike levels at home? Most important, even at these extreme levels — louder than any sane person would regularly play this music at home — the sound wasn’t brash or aggressive, as it is with most speakers; instead, it was very clean, and never short of entirely composed

KEF’s Reference 1 is the best stand-mounted speaker I’ve ever heard.

Overview

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.

All the jaw-dropping performance and innovative engineering pioneered for the critically acclaimed LS50 studio monitor, and then some. KEF Reference 1 speakers pairs KEF’s latest 125mm (5 inch) MF/HF Uni-Q driver array with the sensational new 165mm (6.5 inch) alloy cone bass driver to create a compellingly realistic sound stage out of all proportion to its size. Mounted on shelves or stands, Uni-Q’s inherently wide, even dispersion also makes it the perfect rear channel speaker in a home theatre system that effortlessly reveals all the subtleties encoded in modern soundtracks.

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.
