Only the finest dealers are approved to offer this product. Your purchasing experience should be worthy of a loudspeaker such as this, and should come with matching levels of service and support.

For power with accuracy, the Reference sub boasts two 500W Class D amps, each driving a 9in. long-throw, ultra-low distortion driver, connected back-to-back in the heavily braced, acoustically inert cabinet. To experience the full impact of dramatic on-screen effects, bass definition and control are as important as extension. Only a truly great subwoofer could do justice to Reference standards of home theater, and it does.

Priced as an EACH. Note: All Reference products are hand made to order. Expected build time is 4-12 weeks on all standard finishes.

Product Features

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. Using KEF's ingenious force-cancelling technology, these formidably powerful drive units are connected back-to-back cancelling out the forces they generate, this configuration allows both drive units to operate more effectively, giving noticeably greater definition to low frequency effects.

Cabinet Design

Finished by hand in an ultra-high-gloss piano black finish and complimented by a composite front baffle the Reference 8b looks as good as it sounds. The shape and bracing of the cabinet are computer optimized to minimize secondary radiation from the cabinet walls and distortion from standing waves. With constrained layer damping to absorb residual vibrations, and it's dual opposed drivers the Reference 8b does not allow anything to compromise the purity of the sound.

Composite Front Baffle

The Reference drivers are set in a smooth, strikingly distinctive front baffle engineered to eliminate response anomalies caused by diffraction. Made from an exceptionally strong laminated aluminium/resin composite and secured via high-loss pads and high tensile bolts, it adds tremendous rigidity to the inert cabinet.
