Acoustic Horn Design – The Easy Way (Ath4)

I've already simulated some. So far nothing worth talking about, really.

I don't know, I haven't found it doing anything really useful. The above was 1,4". I have seen better without narrowing the throat.

I even tried to incorporate it in some of my better designs - it was always worse.



I expected some improvement wrt pattern control in the vertical plane. Your waveguide appears to be 60x60°, so it's hard to tell if this is the case.
Anyway, it's probably not worth further exploration.
 
WGs for the Bliesma tweeter(s) are also being developed in this thread.
I think something bigger would be anticipated. I'm all for it, I'd only need a drawing of the tweeter without the grille. It would be nice if the grille was made optionally removable (held in place magnetically), like e.g. on Peerless DA32TX00-08, which could also work pretty well for the money - I have a pair of those (not so the Bliesmas) and may try something with them as well. These are waveguide-ready, so to speak.

Does anyone have the dimensions (a drawing) of the external moving parts of the tweeter? I could try something...

Hello,
M. Stanislav Malikov, the owner of Bliesma is very open minded and I suggest to get in touch with him directly. see the following link:

http://www.bliesma.de/contact.html

I would really like to have some waveguides for the T34B or the smaller T25B !

I currently use a T25B on a renovated "Boule Elipson BS40" from the sixties and I like what I hear...

The grille of the Peereless is also for the radiation patern and not only protection if I remember !



If 1200 hz is possible w/o horn, how low do you expect it to go horned ?


Btw , have you purchased drivers on Sound Imports ? No problems ?
