KEF Reference 8b Subwoofer

Twin 9 inches driver 'force-cancelling' subwoofer

Delivering exceptional bass precision and control with zero distortion, Reference 8b is a truly extraordinary subwoofer.

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.
