KEF Reference 5 Floorstanding Speakers



KEF Reference 5 Floorstanding Speakers

Flagship three-way floorstander

If you're serious about experiencing the ultimate in sound reproduction, the magnificently authoritative Reference 5 exemplifies the passion for innovation that underpins The Reference design philosophy.

Sound

This three-way floorstander aligns four powerful 165mm (6.5 inch) bass drivers with KEF's latest 125mm (5 inch) Uni-Q array and the new vented 25mm (1 inch) aluminium dome tweeter. Lows are reproduced with consummate agility and control, integrating with the midrange to create spine-tingling accuracy and depth.

Two drivers, a single point

At the heart of The Reference is the Uni-Q™ point source driver array. A state-of-the-art vented aluminium dome tweeter at the exact acoustic centre of a highly sophisticated midrange driver that delivers flawless natural sound across a wider listening area.

A strong foundation

Clean, rich and articulate bass is the foundation of great stereo or multichannel sound. KEF's Reference Series bass driver has a massive vented magnet assembly, a large aluminium voice coil and an exceptionally light and stiff alloy cone. Whatever the volume, dynamics and power handling are superb.

The smallest details, revealed

Shadow Flare drastically reduces harmful cabinet diffraction, allowing the Uni-Q to work at its highest level. A precision-designed surface extends the waveguide effect of Uni-Q for improved clarity, particularly when it comes to the subtle nuances of plucked strings and other percussive sounds..

Computer-modelled perfection

Hand finished in pair-matched wood veneers, The Reference cabinets have computer-optimised bracing geometry to minimise secondary radiation from the sides and Constrained Layer Damping to turn what little vibration is left into heat.
