I sadly never heard them, but the Beolab 90 was I think, an early adopter of DSP in the setting up and usage of the speakers. I don't think the thought of using them 'raw' ever came into it as the setting up wa spart of the package.
I remember decades back, B&O and KEF were the first two domestic makers (at least) to have full computerised measurement facilities for loudspeakers. KEF we all know about, but the 1980's B&O Beolab 2500?, 4000?, 6000, 8000 and others which followed all used dynamic eq to get bass from the slim columns, cylinders and lozenges )) they specialised in back then and which backed the bass eq off with level increases. The 6000 was the subject of a thread here eighteen months or so back and in-room, it measures quite smoothly apart from lack of bass extension...
I also question what exactly is the 'ultra high end' in speakers. I suspect it's price that dictates it.
