KEF has a solution for people who don't want a lot of speakers in their room, their new FiveTwo Series. The two models in the series, the floor standing model 11 and stand mounted model 7, split the center channel signal between a driver in each of the speakers (that 3rd one from the top in the picture.) The sides of both models feature flat side mounted driver arrays that shoot the sound out to the sides and, presumably, around the room enough to fill in for what isn't in the back. A special connector is provided with the appropriate leads for your receiver or amp so a consumer doesn't have to worry about dragging three speaker cables to each speaker to make this all work.

I listened for a few minutes and I get what they're trying to do.
