To experience the full impact of dramatic on-screen effects, bass definition and control are as important as extension. For power with accuracy, the Reference sub boasts two 500W Class D amps, each driving a 228mm (9 inch) long-throw, ultra-low distortion driver, connected back-to-back in the heavily braced, acoustically inert cabinet. Only a truly great subwoofer could do justice to Reference standards of home theatre, and it does.
Clean, rich and articulate bass grounds your enjoyment of stereo or multi-channel sound, and like everything else about The Reference, KEF’s new 165mm (6.5 inch) LF driver is in a class apart. With a massive vented magnet assembly and a large aluminium wire voice coil driving an exceptionally light, stiff and strong alloy cone, the dynamics and power handling are superb. Played loud or soft, in delicate passages or for full-on bass effects, the combination of advanced materials and clever engineering delivers deeply rewarding lows that blend seamlessly with Uni-Q’s immaculate midrange and treble response.
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 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.
“A description was needed to convey the idea that every loudspeaker is subject to scrutiny at all stages of assembly, culminating in a final test comparison with a laboratory-maintained reference standard. So the method became the name: Reference.”
- Laurie Fincham, Engineering Director 1968-1991
KEF has never been a 'me too'. We create. And we never stop learning.
The list of KEF patents and innovations is unequalled. Although the Uni-Q point source driver array is our most famous breakthrough, it's just one of many. There's the unique 'tangerine' segmented waveguide. Cleverly stiffened and optimised aluminium domes. Sophisticated vented tweeters. The ingenious use of new materials to boost motor performance and power handling. Constrained layer damping. Acoustic Compliance Enhancement. The brilliant Z-flex surround - these and many others are what account for the reputation of KEF's multi-award winning drivers.
No other manufacturer has done more to advance the state of the art - and no other model personifies KEF's passion for perfection more than The Reference.
