It is hard to understand or describe what might be with Cessaro in Munich. Sometimes even if you are there it is hard to guess what is wrong. To debug Sound you need to go action and to observe how this particular installation reacts to the actions. This is a whole another subject. My nomination of Cessaro as the “best commercial horn loudspeaker” is not an empty marketing label by rather my recognition of the topological configuration that allow to achieve maximum possible results if the all “other little things” were done right. How all “other little things” were done in Cessaro I have no idea, the opportunity are there however.
Anyhow, judging from the images HOW the Cessaro were installed I do not feel that they invested any efforts into that installation and even if the rest the thing were done “right” (that seldom happen) then I would not expect from the Cessaro room in Munich any offensive results. The fact that they dragged the Beta on the show however does make me happier.
The Lansche top model? I really do not know it. Lansche were a company that playing with plasma Coronal tweeters and if I am not mistake then did mostly direct radiators with plasma. I do not think they did any horns, at least I never heard about it.
The dome and Tractrix horn do not work? I do not know. Again, it is about the little things. Avantgarde MF driver is non-compression dome in Tractrix. Does it work? It is hard to judge based upon just one Avantgarde implementation; particularly knowing the Avantgarde implementation is much compromised. I would not closed the book on dome and horn based on the failures of Avantgarde and few others, not to mention that I do not consider the Avantgarde’s MF cha is a complete failure - they did accomplish what they need in context of their limited definition of success.
