I think you're just paying for design at that point, which some people (likely not members of this forum), would value above sound quality. I.e. they'd rather spend 85k on something that looks incredible and sounds 90% versus something that looks average and sounds 100%. I've sat in some home theaters that costed more than this speaker, and they sounded absolutely incredible, but they also involved acoustic engineers to design the room, etc, so that money was spent more on engineering than aesthetic.
I've always dreamt of owning
Nautilus speakers one day. No idea how good they sound. I'm sure for that kind of money, there are much better sounding speakers. But do they look as cool?
Anyway, I would pay for engineering over visual aesthetic, but if I had extra dollars to spend and I already got the sound I wanted, I might be willing to spend for visual aesthetic.
Definitely not 85k for a B&O speaker, no matter how much money I had.
