Post Subject: Again, the last time, about La-horns vs. tractrixPosted by Romy the Cat on: 9/17/2011

Of cause your reply does not cover the subject that I was asking, which is fine, I do not mind. The subtle point that I constantly was trying to make (and that looks like escapes from understanding of the people who are afraid to use the term Lecleach within this site) is that in context of practical results of 4-5 ways vertical horn arrangement the very insignificant HF advantages of La-horns negative opening (primary in imaging department) are getting offset by the damage that La-horns caused by vertical expansion. I do not mention that use of MF La-horns and the rest of horns tractrix is not visually peasant. The constant argument that I have “criticizing” Lecleach’s idea doe not derive to the problem with La-profile but from my desire to look at the horns profile as a part of larger picture. The fact that a full-range loaded La-profile with some kind of Fostex did better measurements at the Lecleach’s test bench does not mean that his findings might be applied to practical playback setup. Everyone do understand the benefits of continue curve at HF (look at my Water Drop Driver) but the whole key is not to advocate the theory blindly but recognizing the theory lessons try organically get out of the theory same practical results. Practically, in my estimation, use of the La-horns increases the minimum listening distance the horn might be properly integrated. If person does not care about it and his planed listening distance to begin from is very large then at this distance the advantage of the La-horns at higher frequencies absolutely has no advantage over tractrix.
