Weren't these speakers (at least in Germany) normally used built-in (infinite baffle situation)? And I don't like the word "open baffle" because it can mean anything. It reaches from quasi-IB like proposed by PHY-HP up to that more and more crazy constructions at diyaudio.com that need massive boosting over the largest part of the frequency range.

I disagree. The "open baffle" term means very specific and very definitive thing. It means that baffle is finite and it has a frequency where the dipole acoustic shortage kicks in. that is the whole point of baffle to be limited/finite in a contrary to infinite baffle where the back way never see front wave.

The infinite baffle and open baffle VERY different topologies conceptually. It is like US Space Shuttle vs. Russian Space Shuttle – both are very same aircrafts but they operate on very different fundamental principles. I do not know how these speakers were used in Germany. If they were built-in to the walls of the theaters then the large front baffle is necessary but I think that were used in stand-alone configuration (Klangfilm Eurodyn or Bionor) as they are used today by their admirers.
