TV between beolab 5s

If you have the tv between the speaker: how do you position the speakers?

I find that if I position the 50"tv anywhere from 10" to about 15" behind the line of the speaker's tweeter the sound may be spoiled, especially if I seat dad center.

But, if the tweeter of the speakers and the tv are positioned on a straight-flush line (less reflections on the screen?), the boomy mid-range is gone, to the point that I'm not using any room correction anymore.

Anyone sharing same experience?
