What Beyma did was marry the Ti diaphragm with a Mylar surround to reduce breakup. The highs are quite pure and smooth as a result. Radian does the same with their Aluminum diaphragms.

That makes sense! Most of the "noise and hash" is from the surround. The 435Be and Al, 2435 and 2431's also use a mylar surround and it works.

I've used a number of horns from A-7, tractrix and other pro hro horns. Materials matter but I think the geometry matters more (CD, exponential, elliptical, etc). Even if you use the best material for a horn and it still has honk or echoes from the geometry, it'll sound sub optimal.
Using a round 10" oblate spheroid waveguide has given me the best results for a much, much reduced horn sound.

Agree that the geometry of the horn is most important but hearing the same design with different materials is quite telling as well.

You should buy what Roy Gregory likes and just link to his reviews to justify
Really !…. As far as I am aware Gregory has yet to critically review or even mention the Symphonia horn transducers in which I have invested my money where my mouth is … unlike yourself ! … Further more I feel no need for justification of my equipment of choice .

Waveguide and not a Horn ...!

They do, not all but many. It has more to do with the horn design but materials play a role and you know this. Why do you think people are using the Klug WOODEN multi-cellular horns as a replacement for the old metal ones? They sound much smoother.

I have been telling no lies so there is no worries about consistency…your trolling, however, is very consistent…

Are there wooden vintage Horns ? Never seen one all i have ever seen or bought were steel ..
