It is in a way ridicules. For years people who build of use horn fight with honk in horn, particularly in midbass-upperbass-lowerMF horns. I built my midbass horns and it has no honk, I mean no honk ever of any kind. Still, I am not content. As I wrote before I do look forward to get SOME very deliberate and very specific honk. My midbassis insultingly neutral, it has fantastic dynamic, fantastic behavior at super high and super low levels, free from any coloration, superb transients, very good discriminates color and set at very proper level in the room. Everything is great but at time I feel that it is too horn-neutral, not tone-sterile but horn-neutral. It sounds like very good quality direct radiator with 109dB sensitivity driven by 1kW amplifier. What I would like to do however is to make my midbass horn to have a very slight pouch of horn honk. Yes, I am taking about a injection to very deliberate non-neutrality and very premeditated coloration.  Sure I will not my horn to have honky sound, we are taking about a degree. I know exactly what I would like to distort in the sound of my horn and what result I would like to accomplish, I just have no idea HOW to do it. Perhaps the bypassing or moderating the high-pass filters would so it, or modification of the throat’s profile or injection of things into mouth, or use some kind of reentry reflectors would do it… I have many ideas but I do not want to go and to try them, not to say the many of them will modify the sound of the horn to higher degree then produce honk. I do not want to change the sound of the horns; I juts wan to add some very very very minor honk, not any honk but  good honk… Did anybody research the subject of deliberate good horn sound?

If it so then I am not very comfortable with idea that when I think about ULF I think about sound. It shall not be this way. From a different perspective what is “good honk”? The “good honk” is not a honk per say but rather a very special harmonic softness that certainly would not hurt my ULF channel. Did the ULF made my midbass horn to sound harder? It is very possible to be so. I wonder how I can test it? I have no way to modify the sound of my ULF and I have no way to change the ULF amplification, which is basically a transistor amp with all consequences of SS not able to produce proper bass. I would LOVE to try to drive my ULF tower with a powerful SET but where can I get 100W SET? I had a few threads hat covered the subject:

… but I am not going to built anything  juts to “try”. It would be nice if I was able to borrow somewhere a SET amp that would be able to output 100-150W but then I realized that it would be most likely a full range set but I would need LF DSET. I might get as a test a power amp with 211/GM70 tube and to wind to it LF DSET transformer with huge inductance and no sections – it will give me some point of reference if it still be in class A. However, I am not convinced that what I am taking is coming from amp not from my drivers in woofer towers or from the way how my woofer towers are built (slightly over damped). Anyhow, I do feel that it does make sense in my search for “good honk” to move the accent from my midbass horn to my ULF thread. If I will do anything about the “good honk” then I will continue my talk in the other, more appropriate thread.
