Which kind of brings me to the thinking… if I do the triangular midbass horns then what shall I do with sharp angles of the horns? The point is that of I do not go for Equilateral triangles then the Isosceles, Isosceles or Obtuse triangles has 2 relatively sharp angles. It means that I will have 2 corners of the horns that will have very limited passing bandwidth. Considering that that horn will be midbass then let say that half feet from the sharp triangle corner the horn will not be working properly. The comet reasonable would be juts choke the long sharp corners of the horn. However, here is where the “kink” comes in.
Where to choke the corner? It is not so simple question as one might think. The choke will be let say a few inches from the mathematical corner and will be in parallel to the opposite wall. It might be a foot or so wide surface. By having this surface it will create a standing wave in the belly of the horn. so, my point is following: if is possible to manage the region what the corner will be cut and the surface of the choke in order to inflict the predictable and desirable LF amplitude modulation in the horn bypass.
This is very-very interesting subject. I do not know how to circulate it but I think it might be effective. The horn rate the horn profile, the surface of the choke and the distance between the choke and the opposite wall – all of it shell be considered and I think it create a permanent equalizing inflection. It would be possible that in the installed and operating horn I could add the corner chokes of the different size and make the fine tuning of the horn response…
Interesting…
