I ask you which speaker you have and you answer in this post nothing about frequency shaded array, also on your linked pages i have not read about frequency shaded

Well, your jumping pretty fast. I've ran my arrays as full range array from the end of 2004 until september 2020. Over the winter of 2020-2021 I have converted my speakers, out of curiosity, to frequency shaded arrays. That doesn't change anything I said, you just had a misunderstanding of my post where I tried to explain that your idea of a single driver above 100 Hz wasn't an array in any form, way or shape.
sure room make too reflections but an array with much distance make even more room reflections and give more dense so maybe can sound depend matter of taste better. It have own sound. dont understand me wrong. when not mix and make music can use what like and sound better. when make music there is a neutral speaker usefull .if like line array sound then use a convoltion impulse for that or record a vocal or so over line array. so it can sound on headphone and speakers more simular. make and mix music on a line array then sound on a neutral speaker maybe not so good as on a line array. And when mixing music maybe use a line array impulse let the sound of vocal or instruments sound better. there are many guitar cabinet impulses and mixed cabinet impulses wav out but no impulse of a line array i find so you maybe can upload one.
The picture I've shown you demonstrates that after DSP the frequency curve of an array shows less bumps and dips due to room effects than a single driver speaker would exhibit. True for both the full range array and the frequency shaded example by the way. Meaning it varies less in room than a single driver speaker would. That
doesn't mean it will make it sound more dense. Quite the opposite.
Actually, if it weren't for the physical senses you get you'd be fine to compare it to giant headphones, but in a good way. Better than headphones because of the imaging/stage and the physical senses. It does sound dryer in-room than the single driver with DSP applied and absorbing the early reflections. Strange huh? How a limited vertical pattern can clean up the results. I hope you didn't miss the tight vertical pattern an array exhibits. It covers seated and standing positions but not much more. It "seems" like it misses the floor and ceiling, while in reality they are virtual extensions of line length. Can you imagine that?
So no! You can't mimic an array with your speakers. In reality I stand a better chance of mimicking your speakers with my arrays. So You'd be better of finding those sound clips if you're really curious.
I actually use more than the arrays alone, another novelty in this thread. As I rob the room of its (obvious) early reflections with my damping panels, I bring back that energy as ambient sound trough a pair of ambient speakers. I could explain it all here, but you'd jump to various new conclusions that are not valid.
If I had an ideal space available, I would do what I do with the ambient speakers in a passive way. Meaning I would have enough room to divert all acoustic energy around in the room using diffractive panels and well placed absorption. Don't just throw away the energy but rather redirect it. My place is too small for that and it is used for multiple purposes (living room) so I do the next best thing I can come up with.
I find a frequency shaded array but the specs are not show clear after which frequency only 1 speaker is used.
https://www.av-iq.eu/avcat/ctl18527/index.cfm?manufacturer=innovox-audio&product=sla-micro . seem all speakers play upto 650 hz because they write "Maintains 25° vertical pattern control to 650Hz"
Another wrong assumption. It is the "array nature" that lets it have the restricted vertical beam like nature down to 650 Hz. That means that more than one drivers are playing and are causing the beam-width to be narrower.
Lets see, the vertical pattern of a single 3.5" driver:
Vertical control down to about... 7 KHz, but in a very limited way I'd say...
Now let's see the array's vertical pattern, 25x the same driver as the above.
Vertical beam width control down to about 200 Hz. How is that happening? With all those drivers? You know what? It is
because all those drivers that it has the limited beam-width vertically. Like a big 15"driver starts to beam way earlier than a 3.5" driver.
Are there any drawbacks? Sure, you see those horn shaped curves in the plot? They are the "dreaded" side lobes of an array consisting of multiple drivers. That is because it isn't a continuous array, but rather a series of 3.5"drivers. Use a smaller driver and those horn like lobes would go up in frequency. One drawback of doing just that, smaller drivers wouldn't be able to play the bottom end, so you'd need a support system down low.
But look at how much energy is hitting the floor and ceiling with that single driver. Depending on the room the ceiling reflection will be at about ~41 degree to 57 degree with the array, and at about ~51 degree in the single driver case. (in my room with a 3 meter high ceiling at my listening distance)
That means the single full range driver would see strong reflections from ~6 KHz on down, while the array would have (a few of) them around 5 KHz - 8 KHz and not much more.
Hey, didn't we see that in the graph I posted earlier?
I think there need limit high freq when want no effect sound. in your case the 0.6 ms is around 1.5 khz. maybe can do swichable if want a neutral or effect sound. with neutral to avoid comb filter effects the highest frequency of the many speakers need at least below 1 khz and only 1 speaker play more than 1 khz in your case i think.
Again with the assumptions... not much of a reality check though... Your thinking is off, as it does not factor in the distance from the array. Comb filtering with the filtered array is a non issue. With the unfiltered array it was a minor problem at frequencies above about 8 KHz. Reflections due to lobes were there too, but no comb problems and the same avoidance of floor and ceiling reflections. Avoidance isn't the right word, as the floor and ceiling even help to make the array seem longer than it is at low frequencies, making the array act like an almost infinite array. Actually making it worth using an array in a room.
I will state that things might not be intuitive right away, but maybe, just maybe some of this will sink in. Many people make too many assumptions about arrays anyway. The theory might be more dense than it's sound (lol).
At least I am happy enough to state that reality lines up pretty good with the above theories. Totally unpredictable, the direct sound vs indirect sound of a line array has a more favorable balance than that of a single driver. Almost horn like in a way, as it controls directivity.
The fun part is: the horizontal pattern is quite comparable to that of a single driver, making the 3.5" driver a pretty good choice. Especially in a rounded, egg shaped cabinet.
I hope this clears up some of your misconceptions. But I rather doubt it. Because even the mind is more dense than my sound is
