Reference 8b

Twin 9 inches driver 'force-cancelling' subwoofer

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

Bass Drivers"

Featuring two ultra-low distortion 9 inch bass drivers the Reference 8b Subwoofer has the power and accuracy to bring your theater to life.

Cabinet Design

Finished by hand in an ultra-high-gloss piano black finish and complimented by a composite front baffle the KEF Reference 8b looks as good as it sounds.

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.
