I saw an uncommon speaker enclosure design some time ago - here at diyaudio, I think - and would like to explore it further. But, for the life of me, I can't recall the name and haven't had any success searching for it.
Here's what I remember about it: The name of the design, presumably that of the originator, sounds European, possibly German. It has an opening at the front that starts as a narrow slit at the top and widens downwards with the sides curving away as something similar to a parabolic curve. There's a system of baffles and channels inside.
There was a link to what was obviously a scan of an old document. I've made a rough sketch from memory of what it would look like from the front. Can you please help find the reference again?
