Floorstanding Speaker Kef XQ 30

The small Kef XQ 30 (2600 euro, pair price) drew even in the deep bass completely with the volume-Goliath Quadral Platinum and was followed by the gnarled bass lines of the Herbie Hancock classic “Cantaloupe Iceland” with astonishing naturalness and authority.

As a little sister of the Highflyers box XQ 40 (AUDIO 3/08) the 30s it has naturally not easy, especially since their list price only to some 100 euro at the top of the range is the series. But the pricing is understandable: through on an extra woofer, the two sisters of the structural work are made comparable; the case slightly rounded in every direction, multiple BA.33, very clean high-gloss lacquered the 30s is worth purely on the outside even money – only at the somewhat thin dimensioned and thus tend to be wobbly terminal you should invest some more material. But apparently it went the KEF engineers here rather to the chocolate as to the packaging, because the in-house UniQ chassis is the outfight constructions of its class.

In the latest version, she got a star-shaped attachment along with sound guidance, called Crown waveguide, which avoids interference and compression effects within the fairly narrow funnel, which on the one hand improves its dispersion properties and to separate the other tweeters and Midranges acoustically more with 19 mm small dome. Because total both sit so close together as otherwise in any chassis of the world: only the diameter inside the medium tone coil is available the entire tweeter with neodymium magnet, dome and waveguide.

The midrange cone to make any big moves, what could shape up the treble in the form of ugly inter modulation effects and Doppler distortion, he hides consistently been exceeding 450 Hz. This means but that of 13 centimeters to reproduce the entire work of basic sound, deep bass and upper bass small paper cone including has – not an easy task, with the bass reflex tube with 38 Hz tuning frequency tuned lower than after textbook and thus significantly lower fails the hub discharge for the bass.

Quiet, please!

KEF offered a bouquet full of timbres immediately in the first bars of Bruckner’s 7th Symphony (Janssons, BR-KLASSIK). This came also the volume control much beyond the 8-hour mark, and the little used exactly this circumstance to the advantage over the still slightly sluggish operating at such Wisper strengths Quadral Platinum. That she could produce also a space drawn far into the depth of well placed votes, earned her a tip as explicit silent handset box. Too turn up should you however not: above of volume the XQ lost increasingly in clarity and Foundation, let her to high levels and the then boastful Quadral almost without a fight in almost every discipline pass; also a certain strain of voices left no longer conceal himself.
