First of all, I want to note that when somebody lives on the principle of denying everything, he risks to live in his own encapsulated world, build according to his own principles in order to feel comfortable there.  

It has nothing to do with fear or desire to live in “encapsulated” world. This exchange worth only as exchange of reasons, nothing else.  I do not see me “denying everything” but I only provide my reasons to agree or disagree.  I do not insist you or anyone else to subscribe my reasonings.

OK, let suppose you are some kind of magician and you made your injection channel to be capable of changing its coloration algorithm according to the specific music material you play at a given moment.

It is absolutely not how it works.

I have control over thousand parameters of my main driver (and not only my main driver, but also my tweeters, my upperbass/lower midrange drivers and my 23” bass drivers!) Choosing the type of magnet system, the geometry of the magnetic circuit, the hysteresis properties of the magnetic steel, the type of the voice coil, the material of the VC former, the INDUCTANCE of the voice coil, the type of the glue for the different joints, the way the sound energy coming from the VC is transferred to the cone, the type of the cone, the geometrical properties of the cone, the type of suspension, the combination of different materials for that suspension (for more complex tone) and literally zillion other variables – I am able to manipulate the tone to any degree I want – I have unlimited freedom to do so.

I have no control over all of those parameters and if I did I would not know how they might affect what I need to get in sound. You claim that you do? Good for you. If you share how they do then perhaps other would understand what you are taking about.

“The driver is what it is and you can't add or reduced colors” – this is valid in your case, but I really wish you to start research in the field of compression drivers and to invent your custom driver which is able to kick your Vitavox S2 right in the ass! I know it is not easy, but I also do not see any reason that stops you not to try it! Only then you will have the sound that you imagine in your mind – your type of sound. But still keep in mind we have already concluded that the less the compression, the better the sound

I do not see why making custom driver would be a difficult and I do not know why it has to be compared to Vitavox S2. I am not sure why you have interests in compression drivers if you did not hear good sounding horns and if you do not recognize horns-loading as advantageous topology. Sure you are free to do whatever you wish but as in anything else I am looking for reasoning…

The problem is that I hear them [reflections] as a specific type of sound signature that I associate with the mechanical device reproducing the signal coming from the amplifier. If I close my eyes and you play for me 20 different speakers, I will always tell you if there is horn type of speaker – my ear (actually brain) is very sensitive to that type of inherent sound signature. Maybe all the horn users have their brains wired differently and they are restricted by the Nature to recognize that type of specific signature. Who knows....

Can you describe more specifically what exactly you hear that indicate for you’re the “horn type of speaker”? What kind signature are you talking about? BTW, did you detect the very same signature in the sound of trained singer or in the sound of well tune symphonic orchestra?

You can think of direct radiators as a kind of very fast expanding horns. They have very slight horn effect for the frequencies radiated by the center of the cone, but the cancellations that you are talking about are order of magnitude less compared to let say tractrix type of horn profile. The cancellations that you are talking about exist mainly in the controllable zone of the cone, so one can almost entirely eliminate them if he knows how to do so.

I do not think about front reflections, neither in direct radiators nor in proper horns (means no step pressure transition). The whole story about reflections is the subject of your invention and I do not mind if you live in that “full of reflections encapsulated world”

If you are happy with the sound in your room, then everything is OK – this is the only important thing of all – to be satisfied by the sound you have in reality. 

… and it is not about being “happy with the sound in room”. I was trying to debate the reasoning, nothing else. Frankly I did not now hear anything stimulating regarding horns. Your objections against the horn loading were not noteworthy in my estimation.
