I've only ever heard these in a showroom. They were fine, but I don't have any particular strong emotion.
Plus, I have B&W800D3s, so I'm not one to pick on the looks of speakers. I know a lot of people hate their look. And they do look suspiciously like a pair of Daleks from Dr. Who. But I like the sound.
That said, I am an engineer by training, if no longer advocation, and am deeply skeptical when people overcomplicate designs. Reminds me of a Jaguar engine from the 1970s. It was like they never got rid of a part when they went on to a new design. Tells me they don't really know how to overcome whatever problem with which they are dealing.
That's my impression with these speakers. They may be fantastic, but there are easier and cheaper ways to get to the same place.
