Nice to see this article again 🙂
I did build a larger version one of these horns in the basement of my old house. I had one more bend with the driver back chamber resting on top of the mouth. It was driven by a 12" AGA driver, more or less a copy of an old Klangfilm driver. It worked very well and filled the house with music for many years. I also tried to make that horn along the lines of another article in the same publication, "Acoustic Compensation" by Rex Baldock.

There are a few of these Baldock type horns around here and have listened extensively to two of them. I can safely say that it is the best bass i have ever heard!
+1, the bass from giant horns are a thing out of this world. Is like the bass from "all other systems" and the bass from the big horn: far more clean.
And, in fact, due to great acoustic impedance matching, the (harmonic) distortion is orders of magnitude lower, and provides a giant reserve of SPL (big dynamics). Is posible to have ear destroying SPL with low distortion.
