Twin 9 inches driver 'force-cancelling' subwoofer
Delivering exceptional bass precision and control with zero distortion, Reference 8b is a truly extraordinary subwoofer.
A CLASS APART The Reference is the physical embodiment of KEF's Total System Design philosophy. Every component is optimised both within itself and as part of the whole, while every drive unit is given the chance to perform to the best of its considerable ability. The result is a loudspeaker that performs far beyond the sum of its parts. SOUND 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. MADE IN MAIDSTONE Since 1973, Reference has been designed, engineered, and crafted in Maidstone, Kent. When you experience The Reference, you don't just experience the best: you experience all of the history that has gone into the creation of the benchmark.
