Loa Subwoofers KEF Q400b Walnut

+ 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 and 165mm 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 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 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.
