SOUND
REFERENCE 1
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, large scale sound stage. Uni-Q’s inherently wide, even dispersion also makes it the perfect rear channel speaker in a serious home theatre system.

Awards & Reviews
DIAPASON D’OR 2017 AWARD
"Plus points: Magic and precise; outstanding low frequencies. Negative points: Nothing." - 2017
Hi-Fi Choice Yearbook 2016
"One of the finest-sounding standmount speakers we’ve ever heard." - 2016
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." - 2014
