Fine processing and graniose joy of playing and outstanding uniformity are the hallmarks of the KEF XQ 40 (3,000 euros the pair) why she was awarded a stereoplay highlight.

- Data sheet
One of the most famous advocates of coaxial constructions is the British speakers KEF, the multiple award-winning XQ 40 at the request of many readers found the way into the history of this principle.
The consequence of which the British their special kind of punk spotlight (the uni-Q) have since soon a quarter of a century and maintain, is admirable. Meanwhile, the driver of even the entry-level models (iQ – series, from about 300 euros) built up always as a two way system are so good that even sceptics hardly from the Marvel come out.
The 40 is the top model in the middle range, which can reach in their workmanship almost to the noble reference series, remains priced but far from. Finally, the size comparable equivalent of the XQ 40 in the reference series (the 203/2) costs more than double.
Bargain hunters and price foxes of all kinds should now be wide awake, especially since’s 40 not acoustically (abundant membrane surface, precious components) is still touch to complain about anything.
On the contrary, because the proposed processing and grab quality is completely millionaire suitable for – whether Terminal, surfaces (gloss varnish on wood) or the metal front milled from solid regarding. All that makes priced so moderately set top model of the KEFschen good citizens League to one of those rare price/value valuables to tout itself audiophile under warranty have to worry.
Technically sound is only very very good. Was it the high-tech housing, shown at right in the simulation of X-ray or the highly complex uni-Q (see drawing) from a variety of meticulously coordinated items.
Compared to previous representatives of its kind and especially when compared with the Tannoy in this test the funnel shape in the KEF coax is only weakly developed. The membrane of the outer music is relatively flat and has little attack area the tweeter for funnel effects and annoying stains.
The tweeter itself, an Alukalotte that is rather compact troubled with 19 mm diameter and therefore pleasantly wide beam, is surrounded by a metal sound leadership that keeps Garcia, and further decreases the influence of the sound through the cone surrounding.
The coax around 16 centimeters wide, coming only above 400 hertz in the game and therefore also from fattest big band hardly required is supported by two equally-sized conventional bass carrying so-called Phaseplugs in their midst. They improve heat dissipation and act as a diffuser.
During a stint in the listening room little settled the KEF from the much more expensive competitors boxes surprisingly impress. Especially liked the 40 with a reaching far beyond their class, uniformity and enthusiasm, whether accented with delicate pieces such as Patrick Nolands piano and sound-ABLES “Nice To Meet You” from the Repertoire of Naim or the roaring up final movement of Beethoven’s fifth in an analog recording from the late 60s.
The Tannoy liked in extreme cases offer more dynamic attack and bass volume, samtiger and cultivated tones the Piega. The high resolution and on top of that room accurate KEF is just price a best buy, as it comes only once every blue moon. Could be one that needed more expensive than new.
Compared to the price extremely demanding equipment fine processing. Sounds wonderfully open and space exactly, level can withstand powerful.
Sound for some tastes slightly too bright and lively.
