Some of the best sound at CES was from speakers that don't officially exist. KEF gave the press a look at their skunkworks with a “concept” speaker called the Blade. In a cabinet carved from carbon fiber, the Blade uses the latest version of KEF’s Uni-Q coincident midrange and tweeter with four woofers mounted in close proximity around the sides of the cabinet to better emulate a point source. The woofers on either side of the cabinet cancel cabinet vibrations. The sound that came from these speakers was simply magic. Driven by Audio Research electronics, I heard spooky, lifelike imaging, high-resolution of detail, and tremendous dynamic swing and punch. Bass and drum kits in particular were simply right there in the room with us. Sticking to its story that this was a technology demonstration, KEF wouldn’t say that this speaker would ever come to market. But the sound here is just too good to keep it in the hangar at Area 51.
