Projects sound not only to the front but also to the side walls to "surround you with the full beauty of music".

Looks like some of the stuff my father made back in the day. Drivers on the corners, firing out the side and in front. At low levels (below say 95dB) sounded quite nice. Would listen/watch for hours without fatigue

Using any cross talk cancellation method necessarily results in extremely tiny sweet spot. That is not good and is totally opposite what I'm targeting here.

I don't like small sweet spot but my requirement is stereo sound to be good everywhere in the room.

It should be obvious that this method relies on side wall reflections, so of course it is room dependent in that regard. First of all there must be two side walls, and secondly they should not be absorptive at the reflection points.
Room shape has some influence and a shoebox geometry seems to be the best.

Also the listening distance should not be too close.

Then comes the timing of direct sound vs reflections, and it is true that direct sound should be attenuated in level at high frequencies. The attenuation is not much about 5 dB I have found to be enough. Actually the way I do the filtering is I simultaneously boost the side elements to better maintain constant power response. See my home page for details about the filter.

Can we say that - in view of the latest developments in Your system - that the SSS project is now - so to speak - abandoned/obsolete?

Looking good.

But, well, it's a pity that it seems no real 'fullrange' system has been built in this principle.

Or, both of them need a lower section in a similar style for bass.

Bass section wouldn't be worth the effort to build with matrixing -- on most recordings most of the bass would be steered to the center driver, and the outer drivers would be largely wasted. It would be best with mono bass - with 3 drivers if you like, but mono.
