If you see no problem, why would you (I assume you do) care about the Spinorama characteristics of a speaker? Or, would want a flat FR?
I mean, I do not see or hear it as a "Big" problem.
Many in here see it as a complete "Failure" in sound. In practice, mine, while not perfect at all, serves its purpose and even when off to the sides, it is simply not as big of a change as some are making it out to be.
Flat FR on axis is quite important to me. I guess when watching movies, I simply do not find it bothersome "Enough" to cause me to be upset or let down feeling.
If the feeling was so universal, no one would be able to stand center channel speakers.
Again, I tried putting my center vertically also, and it was simply not a big change. I know what to listen for but it was a mild change. Not a huge change, despite what the dispersion charts show.
I guess it is a mild enough trade off to not bother me is all.
