Anyway after you living with the injection channel for some time it seems that any lack of focus that I would guess the channel might bring, far outweighs the tone benefits or "decompression" it brings to the table. Now I am asking does this injection channel somehow actually somehow counter intuitively bring "focus" to the sound even though I and probably many other would have guessed it might muck things up causing a little confusion to sound?

I have spoken about it recently

…and multiple times at my site. The injection channel is a controversial subject and everything is upon a specific implementation, how the things done and what the prosperities are.

Yes, the presence of secondary HF source does reduce the clarity of speaker imaging and focus. However that lack of clarity might be observed only very competent gemologist. For sure the presents of a second HF source crate nasty lobbing effect along with many other negative things. However, my injection channel is perfectly time aligned and has no horizontal offset, not to mention that it set o run at minus 12dB. Do I hear imaging and focus improvement what I shut down the injection channel. Yes I do. However, imaging and focus are not “fixed” property that is messured at some kind of absolute scale. Each and single inhalation and each acoustic system in any given room has own imaging presentation and own strength of focus. Macondo with and without injection have just different ways to focus imaging. I would say that without injection the presentation is slightly more accurate but only from the single perspective of imaging focus. With the injection on the presentation slightly more defused but much larger in scale, much more organically sticks to the room’s boundaries, much more “cylindrical” by nature and incontestably richer from tonal perspective.

I do use very specific categories but I am the person who knows Macondo sound well and I know what to look for. A regular audio person who did not invest as much time into Macondo does not notice the contribution of injection channel even if I point it out. I have many time when my visitors asked me to flip the injection on and off, something that I did and none of them got the change right the way. Usually after 5-6 flips they do get the very fine difference and I did have some people who did not recognize the difference at all. What I am saying is that the contribution of my injection is very minor on general scale. I personally do not feel so and for me the injection provides huge difference that appreciate person and I do not intend to lose.

Is injection a compromise? Yes it is but I do not know how to make my drivers to be able throw definitive amount of tonality. I have no idea how moderate warmth of tone or color saturation in compression drivers. So, I use injection. If my horn drivers might not be benefited by my injection than I would not use injection at all. It is possible that such drivers exist out there but I do not have them and I have a lot of reason to feel that they might not exist.

Ironically it is very easy for you to test the whole injection concept and to make your own judgment about it’s benefits. I very much do not defend what I did. My playback is for my own benefits and I know what I get from it. If the injection does prevent you from sleep and you are looking for answers then just try it, that what I would do if I were so curios. Borrow 10’ old Tannoy Red driver, mount it in the box you have and spend a few days of listening it. Learn for yourself what this driver does right and wrong. Then try to combine what the driver doe right with the sound of your main inhalations. If you use only vertical plane and time-align the injection with the rest of your channels then you will have an illustration how it works.
