Some time ago I also thought my upper bass channel is flawlessly integrated, but when I added another, symmetrically arranged UB driver (over my WR driver), I quickly understood the new configuration is MUCH more expressive and full-bodied sounding compared to a single UB channel. The upperbass started to breath completely effortlessly and it was perfectly centered at the WR/midrange driver’s axis. So it should be experienced to be appreciated…
Haralanov, let do not create confusion at least in our own minds. Of cause the things need to be experienced to be appreciated. The fact that we exchange verbal assessments over Internet and not able to demonstrate to others any tangible result does not need to be stressed – we all understand it. What we trying to do is to exchange ideas and views. So in my view what you advocate might not be what you think. When you add a second, third of even forth driver in upperbass you do a lot different things but the most important you reduces the exertion of each individual driver by factor of 2, 3 or 4. Doing it immediately convert any driver to a driver 10 times better. You also incused the radiation surface and form micro-line array that has a LOT of advantages to full up the room. Everyone knows that piling up more channels/drivers has benefits. You propose to use the lower directivity of upper bass and go horizontal. Possible but debatable. Of cause it will have benefits but it also will have some shortcomings and I can very clearly enumerate them. I think it is impossible to evaluate all of on sitting in front of a sheet of paper however…. BTW, there is no need to agree. Everyone has own idea how we all build the things from scratch.

Yes, of course the multiplication of upperbass in a way eliminates the ability (but not exactly) to put the midbass horn in right position, but who cares about that, given the fact that proper placement of upperbass drivers is at least 10 times more important than the placement of midbass horn? Cat, you have placed your midbass horns on the roof behind you and you don’t feel it is wrong, so why did you suddenly decide that arranging the midbass horns sideways of the whole upperbass stack (where they should be) is problematic?
Where did you see me advocating that my behind-above (not just behind) positioning of the midbass horns is right one? Of cause it is wrong and if I had an opportunity doing playback and room from scratch I would of cause go for frontal positioning, something that I would not be able to do if I has 8 upperbass horn in front of me. Also, I do not think you clearly understand the disadvantage of the “midbass horns on the roof behind”. You see I would get absolutely identical sound with my midbass horns in front of me, behind or behind-above. I just would use the midbass in context of entire playback very differently if I had more beneficial location of my midbass. I can only assure you that if you were in my room then you had no idea that big horns are where they are. Well, so far no one was able to, which does not mean that it is impossible if to know what and how to listen. It does not make my location for midbass horns “right”. It let me to worship my ego and feel that with my playback setup experience I can go away even with that but it does not make the things that I do to be right things.

If I have to think further about this, I see no option to use a midbass horn in close proximity to the midrange channel (even if there are NO upperbass horns there) simply because it will act as reflecting wall for the midrange channel (if it is placed in time aligned position)… So all these upperbasses practically do not eliminate the option for proper using of the huge midbass horns: [image] 
For what it worth I feel that in the case you depicted the right and left channels need to be positioning wider compare if it was regular Macondo configuration. How many people have extra width with no first reflection from the wall in upperbass?
