Duette
The Duette is an entirely new approach to loudspeaker design. No other compact system contains so many outstanding technical advances.
The B.139 and T15 units are incorporated with a seven element printed circuit crossover network in a cabinet of optimum size to give flawless reproduction over the full audio spectrum. The bass reproduction is quite astonishing from such a small enclosure. Organ pedal notes and the bass instruments of the orchestra are brought out with amazing clarity and weight, due to the special electrical compensation provided to offset the effects of cabinet diffraction. This is another KEF exclusivity - no other domestic high fidelity speaker incorporates this feature.
Very great care has been taken with the tonal balance of the mid range to ensure naturalness whilst very high frequencies are radiated without noticeable directional effects or stridency. The sound from the Duette can only be matched by the biggest and most elaborate systems.
Finished in selected hardwood veneers and available with a choice of oiled American walnut or teak with coffee fleck grille.
