KEF Audio Uni-Q User Manual

The new Reference Series embodies an
approach to pure sound using technologies
found nowhere else.
Although the single point source performance
and wide dispersion characteristics of KEF
Uni-Q are well known, the new range is based
on a radically new design: the first ever Uni-Q
driver array dedicated solely to the midrange.
The limited movement required at these
frequencies allows a perfectly flat new
surround that dramatically reduces diffraction
and intermodulation effects.The filled
polypropylene cone and its thermoplastic
rubber surround are produced as one entity
by a patented co-moulding process, while the
cone profile is optimised by Finite Element
Analysis (FEA) to ensure that wavefronts from
the tweeter exit the cavity cleanly.
Another KEF ‘first’ is the small, superlight
compound neodymium magnet assembly that
ensures optimum flux profiles for both MF and
HF coils. Its low mass allows effective
decoupling from the cabinet to prevent box
colouration, and the open chassis design
(in die-cast aluminium alloy for stiffness)
minimises acoustic reflections behind the cone.
Determined to set a new standard of
mechanical integrity for metal dome tweeters,
KEF engineers also used FEA to develop a
unit whose resonance threshold exceeded
30kHz.The result is a deep drawn 25mm
titanium dome with elliptical profile and
optimised surround that substantially
outperforms conventional high-end units.
The imaging therefore becomes even
sharper, with virtually no colouration.
Integration is flawless; the off-axis response,
unrivalled anywhere.
