REFERENCE 1

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 REFERENCE

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.
