That's right! Why FIGHT with your corners? Use them to your advantage!!! 
You know, I have been fascinated by these for years. I think if you had four of them, two in the top left and right corner, and two in the bottom left and right corner, it would sound great, of course you'd have to sit on the center axis of the room, etc. And perhaps process so that the upper channels had a higher volume, etc.
Or you could just build speakers into acoustic products...
