Hi Romy,

So did you try damping the diaphragms or not?
I have also had good results as well with very little PVA based "art varnish"


I also have a question regarding what you said an earlier post in this thread;

--- Snip from earlier post ---

3) For some reason removing the tweeter’s screens apparently screwed the phases somehow (soundstage allocation). I began to have a difficulty getting my “Trio Sound”. In my room properly set, properly powered and properly “massaged” Trio horns usually “compress” air and produce what I call a “hurricane/tornado effect”. I use to be surrounded with thick and tangible clouds of compressed air that spun around intensifying space and musical time, filled with bubbles of Sound, appearing and exploding somewhere within the room, opening the sealed-within music memories and revealing Life. Since screens were removed I had only the beautiful “wide and deep soundstage”. In fact, I am still able to create my “hurricane/tornado” effect however it happens only within extremely small listening space that eliminates some desirable listening experiences. (Like exploring the Sound from the “side”, ability to “walk into the sonic event”, to “conduct” the orchestra by changing the listening position, to “torment the Sound” and so on…) I spent a long time moving everything that was movable but I failed. For some reason without the screens the heights ground down my attention to reality. I am sure the engineers would explain it more intelligently than I do.

Do your current horns "compress" or "do the
hurricane/tornado effect” as well as your former Trio's?
I know you wrote later the trios are "duller" or something like that, than your current horns but i mean specifically in this regard, "exploding bubbles"
Could it be this is related to compression ratio ?
Edit--> just looked at there site and there range seems to have changed since last i have seen them years ago. Back then i remember that the throat was much smaller. I geuss they changed that because the sound was too colored (just geussing)
I remember them very slowly expanding like like a blown instrument.


Also you discribed the removal of the screens messed with imaging off center.
My geuss would be the screens created a more stable wavefront across the diameter of the throat that stayed "intact" longer while traveling towards the mouth.

Did you ever get the screens installed again back then and still observe the same effect?


Still reading...

Regards,
Collin
