Thanks Romy for showing us this work and the thoughts of its creator(s).

I'll say it again; the world needs more people like these guys: Human creativity remains the only saving grace of an otherwise pathetic species.

It would be most excellent if Klaus and Reinhard (Reinhardt ?) would consider sharing more of their experiences here (text, or just images), though I'd completely understand, and would actually expect to find them very reluctant to do so.

Reinhard wrote:

"... Midbass horns: There are two 20 cycle bass horns which normally have 6,50 m in length and 3,20 in mouth diametre (we had that for testing purposes and we thought, well, that's it, the space is there and the depth to be able to listen to, but to our surprise it was not ! they didn't perform that well, astonishingly neither with natural nor electronical time alignment), so Klaus cut them down to 4 m to get rid of the time delay..."

Interesting: Physically cutting off a horn 2/3 of the way along its flare, where gain is happening, but is not yet really accelerated, and letting the room take it from there... With driver sensitivity at 113dB/Watt, it may well be possible to forgo some gain. I'd like to know more...

"... Also it is very “kinky” moment how the delay from upperbass interacts with the delay from midbass. I know that not a lot of people would understand it but there are ways to “spread delays” or to use what I call the “distributed delays”. This system would be a perfect playground to experiment with it..."

The above statement and images of the system have me curious... I assume that at least some time alignment is done via electronic delays (this is possibly what is meant by "RESP" ???). Again, it would be interesting to hear from Klaus and Reinhard on this subject.
