Thiel powerpoint speaker

[Rijang]

Hi, my first post. If I understand it correctly DSP speaker such as Kii and D&D uses DSP for controlled directivity to reduce effect of sidewall reflections. I have the Thiel powerpoint which is supposed to be mounted on ceilings or wall. I currently have them mounted on sidewalls and I think they sound pretty good compared to my other speaker (Volent Paragon). The question is ,does Thiel's claim of the speaker's shape and configuration ( firing 45 deg from sidewall http://files.d-tools.com/Visualizations/Approved/Thiel/Documents/Thiel_POWERPOINT 1.2_Brochure1.pdf) have a scientific backing from acoustic point of view? Why is this not pursued by other manufacturer? Thanks
