Any in depth Reactor reviews or users here?

From your graphs I understand that the problem is not with the Reactors or the Wilson Benesh speakers but with your listening room. The fact that the SAM equalizer does not solve the problem tends to confirm this.
If moving the speakers away from the walls does not solve the problem, then I agree that some kind of equalization is needed. The Phantoms' Spark app provides a "night mode" to lower the bass output, so there is no reason why they could not provide the same mode in the Devialet app for the Reactors...
All I can say is that when listening to the reactors in an open space such as an outdoor terrace, there is no audible bump in the bass. In a small bedroom, the bass becomes heavier, but not in an annoying way to my hear at least.
