All the jaw-dropping performance and innovative engineering pioneered for the critically acclaimed LS50 studio monitor, and then some. REFERENCE 1 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.


The standard by which others are judged, and to which they aspire. The perfect reproduction of recorded sound is what KEF's legendary THE 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.

SoundStage! Network - Reviewers' Choice

"With the Reference 1, KEF has raised the bar for stand-mounted loudspeakers in several ways. In a flash, my wife picked up on the speaker's high-tech appearance and attractive styling. The high level of technology applied -- most notably, the current generation of KEF's Uni-Q coincident driver -- seems nothing short of an engineering marvel. But most important is the Reference 1's quality of sound -- within its bandwidth, it's as accurate as it is musically engaging...KEF's Reference 1 is the best stand-mounted speaker I've ever heard."
