KEF and the KHT story

The more sophisticated that digital audio

formats become, the better your speakers

need to be. Which to choose, though?

Manufacturers come and go. Design trends

appear, then fade away. But with KEF,

you’re dealing with people who’ve been

consistently innovating since 1961.

Uni-Q

KEF’s patented Uni-Q driver configuration

disperses the sound image over a much larger

area than a conventional speaker, instead of

being restricted to a small ‘sweet spot’.

This outstanding off-axis response is made

possible by using aerospace materials to

engineer a high performance tweeter that’s

small enough to mount in the exact acoustic

centre of the bass/midrange cone so that both

act as a single point source - an ideal that, so

far, only KEF has achieved.

Conventional loudspeaker dispersion showing

narrow ‘sweet spot’

Based on those developed for the legendary

Reference series, the Uni-Q arrays in the new

KHT range are the most sophisticated yet,

with new metal dome HF drivers that

reproduce the human voice with breathtaking

accuracy. In purely practical terms, the larger

sound image gives you far greater flexibility in

placing your speakers where they look best.

For home theatre, it means that you experience

even the subtlest 3D soundtrack effects with

the same clarity and realism wherever you sit.

The holy grail of loudspeaker design has always
