Were no thumping bass beats to reflect the small KEF XQ 20 (1800 euro per pair) recalled her big sister XQ 40: exactly defined, but drawn beautifully into the depths of space.

All in one point
The XQ 20 is of course on the chassis hallmark of KEF: the UniQ of called coaxial speakers. At the 1800 euro expensive compact box that remains even the only sound converter – the finely curved box have to forgo an additional source of bass. Because the cone membrane thus must play at the same time larger bass strokes, but serve also as sound leadership for the embedded tweeter, coaxial 2-way speakers are basically once prone to intermodulation and other unsightly interactions between two chassis.
KEF has optimized therefore especially the shape of the membrane and the rigid metal sound unit to the tweeters around in the latest version, so that the tweeter sound not in affected is pulled even with violent movements of the music. Among other things the referred to ‘Crown ‘ waveguide metal braces, designed to prevent resonance reinforcement directly in front of the tweeter diaphragm serve the same purpose. Because the Interior of the cone membrane acts as a large Horn mouth – and older coaxial speakers, which are not as mature as the UniQ, exhibit in the area between 7 and 15 kHz typically quite sharp resonances and cancellations.
The material was used on classic: the cone measured 16.5 cm is a very clear Cabinet and therefore stiff soft polypropylene model, the 19 mm small cap consists of a metal alloy. Thanks to the pressure amplification through the sound guide she can be used already at unusually deep 2400 Hz, making the box as a whole has a clear but very regular bundling behavior – and the Polypropmembran must no longer be used in the area of their partial coloration. The KEF designers outside of the chassis were slightly less trouble: both the bi-wiring Terminal and also the somewhat thin troubled internal cabling rather address the pragmatist than the high-Ender.
The latter should reconcile themselves but at least by the sound of the high-gloss painted sculpture can be: instinctively safely positioned votes – particularly in stage and sacred works such as Bach’s “St. Matthew passion” (Kuijken, challenge Classics) noticed this striking course in illustration and detail view. To do this she offered one emphasizes gentle, but natural tone colors with good illumination of all registers.
Her bass Foundation was not dominant, can but given the size of the case considered to be amazing and ordered to Miles Davis’ “Tutu” very conducive to music in the a. An extra woofer testers missed no more than if you tickled the XQ 20 with really nasty deep bass attacks at hefty volumes: then the KEF lost some of their swing and the loose taken for granted again. But most listeners are in the living room anyway not realize such level, but enjoy a very harmonious, beautifully-forming compact box.
