SOUND

REFERENCE 8b

For power with accuracy the Reference 8b sub has two 500W Class D amplifiers, each driving a 228mm (9 inch) long-throw, ultra-low distortion driver. These are connected back-to-back in a heavily braced, acoustically inert cabinet. The result is low distortion bass with effortless body and weight.

design story

THE REFERENCE

Simply power up and pair using Bluetooth 4.0 with aptX® for sensational cable-free audio. Or, if you want to unlock the potential of your computer based audio or TV sound, including hi-res, choose the micro-USB or optical inputs.

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.
