Does the stage width change when you switch off the subs?
Nice! Did you document your room construction somewhere?
No.
Well, there are bits a pieces of it in my long dipole construction thread, but not in all too much detail.

The short version is: damped front-end, diffused rear end.
For a "lifelike" representation of sitting 20 meters out into a concert hall, you need to image yourself that you have that distance, which you really can't physically have at home. But our eyes trick us. If you close your eyes, can you really tell how far away a sound source is? You can't. But the amount of reverb, hi-frequency attenuation and other clues will make us guess. And that's some of the point. A very closely located speaker system can actually fool us into believing that we are 20 meters away from an orchestra in a large concert hall.
Personally I don't relate to recorded music as a representation of reality, because its not. I think of it more like watching a movie. You have the action there on the screen as a "window" you look into, you are not really "there" as it happens.

pieskapov's system gives tremendous space too. The speakers are 2,5m from the listerner and 2m apart. With a good recording of classical (orchestra or ensamble) you can "see" them at 5-15m distance and 10m wide. Totally depends on recording. A very nice "picture"!
With eg. Pink Floyd recordings you can hear all sorts of xyz-perspective effects like someone whispering at 90¤ to the side etc. We can't tell if these effects come out as defined, but it is very impressive. If you move out of spot you loose these but retain the overall good sound quality. If the spot is wider, I guess these effects are thinner? Less listening distance might improve imaging of a wider dispersion speaker?
My goal for Ainos was to get moderate directivity with best possible control because I can hardly ever listen at the sweet spot... I have not yet heard them as stereo, so I can't tell what the outcome is. From auditioning just one speaker I am a little afraid that I got too much horizontal directivity... On the other hand my living room is more lively than my HT room (RT 0,3 - 0,4), it might help to retain bright power response in the room.

Wow, I would not expect that from such a narrow positioning of the speakers. I have mine a bit further apart and I always thought it is because of the distance between L/R speakers. I sit about 9 ft away from speakers. I do notice if I shorten it up the soundstage improves. I have to play with it.
only 10cm?! That extremely tight listening window. I will have to see if my window is just as narrow. Since I am doing other measurements on my system right now, the room measurements will be done possibly next week. I'll start with ETC and go from there, with guidance of course
Ha ha Thanks all. Now, to go buy me some books on the subject
Jeez, it is really difficult to draw conclusions of this. What is the speaker and what is the room?
Normalized overlay of AINOproto and AW-7 0.3ms smoothing to emphasize differencies
p.s. the differense in level before 0ms comes from difference of volume (spl) used in the measurement. Measurements were not taken after another, but otherwise in same speaker position and mic position.

Juhazi,
Graphs are easier to compare if both use the same scale. The interesting data in an ETC is the first 10ms over about 30dB and the overall slope within the first 500-1000ms. The latter should be examined in frequency bands in order to get a feeling if the absorptive behavior of the room is broadband.

overall my etc and Rt are good.
Here are some graphs that are shown at a Finnish site (dipoles in living rooms)
