KEF Reference 8b Subwoofer
KEF REFERENCE 8b delivers exceptional bass precision and control with zero distortion. Only a truly great subwoofer could do justice to THE KEF REFERENCE standards of home theatre, and it does.
Bass definition and control are as important as extension in order to experience the full impact. REFERENCE 8b sub boasts two 500W Class D amps, each driving a 228mm (9 inch) long-throw, ultra-low distortion driver. These two drivers are connected back-to-back in the heavily braced, acoustically inert cabinet.
