I visited Tim Jarman this week and he has acquired some more Hi-Fi Year Books. Well, I was leafing through a few and, for at least three of the volumes covering the early to mid 1960s, the only B&O item listed under the 'Speaker Enclosures' section was something called the B&O Trapezoidal Tweeter.
Now, I've never heard of this, Tim's never heard of it and neither, it seems has the internet! Sadly, there were no pictures, only a brief description of it having two tweeter drivers plus a trapezoidal reflector between them - it almost sounds like a forerunner to the Beovox 2500 cube and maybe a very early version of ALT!
So, out of curiosity, I was just wondering if anyone had ever heard of, or seen one of these?
Perhaps the 1961 "Rundspreder" ("Roundcaster"):

Actually a 360-degree tweeter so in that aspect way ahead of ALT.

Interesting - not heard of that before. That could be what the books were referring to.
