I have never heard a Boenicke apart from the youtube videos and I liked what I heard. Its interesting that folks who are interested in Cube are also also interested in them as I am. I would be highly interested in a comparison between the two though I am not sure if this would be the right thread. The amp requirements for the Cube and Boenicke are on the opposite end of the spectrum.
The Raido/Børresen in shows always have a wider placement configuration very close to the side wall with aggressive toe-in towards the listening position. Maybe they don't care for the sidewall reflection based on how the speaker is designed. I am still playing to the positioning with the Nenuphars and experimented a  little with the toe-in and I find aggressive toe-in make the sound too bright and sharp for my taste. Currently they are toed in about 5-10degree. How much toe-in do you guys have ? Between, anyone using a pair of subs with the Cube ? 
Initially I had my Cubes pointed straight ahead but have found they do sound better with a slight toe-in. Haven't tried corner placement because of furniture constraints.

Boenickes and Cubes are quite different animals but share something that I find attractive. It might be called flow or a more natural sound. I don't care for speakers that "push" music at me.

Btw, I just wanted to say how exemplary this thread is. Just pure, helpful, experience sharing and education. It's really a pleasure, thanks.

@stephendunn  Congratulations on your success with the Vinnie Rossi integrated and resistor solution.
