After we left Thorbens domain and headed towards the viewing room, we went through a central room where we had a quick coffee.
On the walls of this room were many posters. I think a lot of them were of designs that students had forwarded to B&O.
This one shows a potential "Mobile 2" and I think the strange contraption on the right is a Beocenter of some kind. Quite interesting, in the bottom right hand side is a remote control which is worn on the hand like a knuckle-duster.
Edit-- I have removed this photo'. It may have breached an agreement we had with B&O. Sorry, Andy.

Thanks for that, Andy. 😁

From the viewing room we moved on into the listening room.
This room was quite small, about the size of my lounge. Across the front of the room were some large curtains hiding speakers we couldn't see. These curtains were made from Penta fret fabric so they were acousticaly transparent.
Every item on the wall was there for a purpose and, I think, the rear wall was acousticaly dead but don't quote me on that.
We were played three different tracks and asked if we could guess what speakers were hiding behind the curtain.
The first track was classical music (Mahler I think) and the sound was truly wonderful! From my seated position the bass and midrange seemed to come from about the same height as my head but the higher tones seemed to be coming from way up high near the ceiling
This made me presume we were listening to two pairs of speakers. I was unsure of the lower ones as they sounded every bit as good as my Beolab Pentas at home. but the ones up high had to be Beolab 3s or possibly Beolab 4000s.
