9 section horn (hasn't Romy been discussing odd numbers of petals for years?). Unfortunately no discussion of sound...........

Where is the “horn needs”?
fiogf49gjkf0d
Well, this is what I call “beautiful but” category. Unquestionably it is very creative, firm, light and very attractive, and it is wonderful to solicit appreciation of simpletons-morons who did so in the comments.  There is no need to talk about sound of those things- it is irrelevant and will depend from many other things.  What is possible to talk is design objectives and concepts.

The whole story about horns is interesting as you can diamonds-plate the horn but the horn does not care that it shine like a diamond and cost as much as national  budget of small African country. Horns what they want and the whole artistry to make horn installations is to let the horn needs to dominate but in the same time to pursue the aesthetics and many other human objectives. 
 
From the aesthetics perspective Jeffery did phenomenal job but from my perspective he did not fulfill the “horn needs”. Of case the odd numbers of leafs is mandatory and only God in his infinite wisdom knows why the morons who do leafy horse keep making them with even number of petals. I am glad that he deviated from conical profile – that was not good idea in my view. This looks like early terminated Tratrix to but mentioning this horn as tribute to late Jean-Michel Le Cleac'h is absolutely ridicules.  This type of horn has huge termination problem, ironically it was what Jean-Michel was fighting in his design. Those multi-faced sharp edges at the break like are very bad, do not forget that they ae not at 0 degree as it would be with full Tratrix but they looks like at 70% degree.   That is very bad. Also, the “randomness” of the profile at the termination edge “looks” like nice, the problem that for the frequency the horn will be operating (looks like MF) the “randomness” is to large. 
 
So, if it was me then I would smooth the  bends at the termination edge but I do agree that it will kill the sexappeal and photogenics of the horn.

We need to wait for the implementation

Jeffery has done some interesting stuff and I am interested if he shows how a system with this generation of horn is implemented. Because they are both out of different woods, I assume that these are first prototypes.
