KEF Q400B Active Subwoofer - NEW Black Finish
The multiple award-winning Q Series has always exemplified KEF’s conviction that new materials and technologies can, when applied with intelligence and imagination, reproduce recordings so perfectly that they sound indistinguishable from the live event. This is more true now than ever before. As the latest expression of this design philosophy, the new range immerses you in three-dimensional imagery of a richness and clarity that until now has been the exclusive preserve of speakers costing many times more.
The all new Q Series from KEF represents a quantum leap in terms of listening pleasure.
At its heart is a brand new Uni-Q driver array. Derived from the Concept Blade project, with a new, larger, high performance vented tweeter mounted at the acoustic centre of a new metal cone LF/MF driver, it combines lavishly extended bandwidth with effortless dynamics, imperceptible distortion and outstanding acoustic clarity.
Reproducing most of the soundtrack narrative, the centre speaker is by far the most important in any home theatre surround sound system, and the Q200c and Q600c are engineered accordingly.
With a new generation 130mm (5.25in.) and 165mm (6.5in.) Uni-Q driver array respectively, flanked by a low distortion bass unit and an ABR of the same size, they combine raw power with the subtlety to convey moments of great delicacy.
What you notice is how convincingly the larger new metal dome tweeter captures the emotional range of the human voice – mood and character shine through with real clarity.
Your involvement in the action is noticeably enhanced by the addition of the Q800ds dipole to convey the left and right rear channels. With the two 130mm (5.25in.) Uni-Q arrays on each speaker playing out of phase, ambient 3-D effects are completely diffused throughout the listening area to create an uncanny illusion of actually being there, whether that’s deep in the rainforest, in a concert arena or driving along a gritty urban back street.
The final ingredient of your new Q system is of course the seductive Q400b subwoofer. A closed box design housing a 250mm (10in.) woofer driven by a 200W on-board Class-D amplifier, this discreet cube creates spectacular bass imagery – eloquent, musical and addictively physical. Anchoring the whole sound performance in an all-embracing sensation of immediacy, it completes the acoustic picture.
