Dose the midbass horns semi-mono location has an impact to the “width” of playback. Yes it dose and I did clerlay expressed it in posts what I played with idea of width modulation channels.

Romy, I think that I now understand better what you are trying to achieve and yes it is a very complex area.

I do feel that what Robert propose might be experimented and use but NOT at the design stage. The design concepts need to relay upon dealing with straight signals. Then, after the straight operating playback is set, then one can see what else might be done and how different intentional additions work against the non-compromised signals.

I respectfully beg to differ. See my previous post on the question of what to consider at the design stage. Of course, short and straight signal paths must always remain a priority but this does not mean that these spects of playback ought not to be considered at the very earliest stage. I would go so far as to suggest that you yourself considered these very issues at a very early stage before you had even made an offer on your new house.

In the end - a comment about “reproduction of the subaudible signal at the same level as the audible bandwidth”. It is not necessarily what it is. There is no same level, hyper-elevating level or elevated level. When we hear live sound then we have no “level of space” and we subconsciously get the messages about “space” from naturally-long reverberation time, from visual aspect and from another sensors. Recordings does not have this information, the listening rooms has near close decay time is necessary (The Symphony Hall in Boston has drop at 60dB for 1.5 seconds), not to mention that ULF information is severely distorted on recording. So, the idea is do not correlate the ULF messages with auditable signal but to separate them and to run ULF at the level that creates SIMILAR sensation as it happens during live event. The keys in it to have ULF do not affect the audible signals, to have a feasibility of ULF level, to have front of ULF time-aligned, to have the ULF leading edge as compressed and sharp as possible, to have a room that will be able to dissipate the ULF decay evenly. So, it is not about levels in terms of dB equalization but rather about of equity of perception. I do not even know what the objective level of my ULF. My ULF is higher than it would be with a linear single driver that would 20Hz-20kHz bandwidth but who said that linearity is a part Reality? I so not even mention that in audio we do not deal with Reality but we deal with very barbaric ways to mimic Reality…

Hamlet:
Be not too tame neither, but let your own discretion be your
tutor. Suit the action to the word, the word to the action, with this
special observance, that you o'erstep not the modesty of nature. For
anything so o'erdone is from the purpose of playing, whose end both
at the first and now, was and is, to hold as 'twere, the mirror up
to nature; to show virtue her own feature, scorn her own image,
and the very age and body of the time his form and pressure. Now
this overdone, or come tardy off, though it make the unskilful
laugh, cannot but make the judicious grieve, the censure of the
which one must in your allowance o'erweigh a whole theatre of
others.

Hamlet (3.2.1-16-28)

Romy, I understand much better your position now and as you said, without actually listening to the results, it must be impossible to form a definite view one way or another. I would however surmise that irrespective of how successful your implementation of your ideas have turned out to be, there is a risk that one paints very different recordings, made in the most varied conditions, using widely varying techniques, and engineered God knows according to how many different recipes, all with the same brush and end up like Hamlet warns, in his exhortation to a travelling band of actors, 'overstepping' what's on the record to recreate what may not have been either at the performance or on the record in the first place.

I am trying to keep the discussion about midbass horns out of ULF thread, I guess if Rakesh would like he can create a separate thread dedicated to his specific installation and the design ideas. I would like to keep the content of the posts more or less related to the subject of the thread.

I should have done (started a new thread) but I thought, maybe mistakenly, the query I had was so closely connected that it was somehow relevant.

I apologise to all for having, in what looks like a very cavalier fashion, but this was not the intention, taken this thread off its course.

Regards
Rakesh
