I'm always amazed at posters with strong, authoritative opinions about gear they have never actually listened to. Often based on articles written by unidentified others of uncertain skills and interests. Usually with incorrect information.
After years enjoying most of the higher B&W models; discovered Wilson Audio. My ownership experience with Wilson started years ago with the then new, Watt-Puppy 7. Still a desired speaker. On to the Sasha and for the past years, the excellent Yvette. Spent plenty of time at dealers listening to all of their speakers.
Wilson, in certain models, intentionally wires the midrange out of phase (backwards) with the speaker's bass and treble units. It's done, of course, in the service of increased sound quality and is fully considered in the design of the crossovers. The ultimate result is verified through electronic testing and extensive listening sessions. Can't tell you if any I've owned use that technique. but they all sounded great.
