like a pendent lamp ... a chain from the ceiling. Back when I was an undergrad I worked as a tech for the Dept of Electronic Music at the University of Illinois ... the head of that department designed a pair of round faceted speakers that looked to be over a meter in diameter with drivers pointing in all directions. I saw and heard it once in a concert (with a drummer) but the music was one of his compositions and ... "electronic".

I'm missing to reason to the downward tilt to the curves as I thought that only had to do with matching the sound power of a bipole ... and ditto on being included on the blind test.

In the listening window with walls in place ...
