So, in your opinion, point-source is not as good for spacialization than using many drivers?
Point source is ideal for imaging and gives you the most accurate reproduction of the source material, including its space. The big sound with an exagerrated sense of height that you get from towers like the Salon2 is more pleasing for classical music and movies. It is just a bigger, more impressive quality of sound that makes the content more immersive and grand. I'm not sure quite how to describe it. It isn't quite as good for properly reproducing the space and objects within it, but it is good for creating an effect of spaciousness.
However, when you add in surrounds and height channels, you also get a huge sound from small speakers like the Genelecs. What sounds better in a full immersive audio setup is another question. I would argue that point-source coaxials are better for this because they can more accurately reproduce height information with their good vertical directivity.
