bman, that TV will mess with the "Early Reflections" curve. That curve is responsible for image width, stability and timbre and is taken at +/-40, 60, and 80 degrees across and 50 degrees up and down. Of course Axiom may actually take those curves at finer angles but the point is, that TV will interfere with the curves from 31 degrees all the way up to 90 degrees. It will also mess with the sound power and directivity curves.
You can see this if you form a triangle with legs of 3" and 5" and solve for the angle between the 5" leg and the hypotenuse.
I have no idea how audible this might be in your room.
Of course Ian knows best. For all I know, Axiom may have adjusted for the "TV effect" but I highly doubt it. Now if you had active M5 in-walls...well...maybe that TV effect could, to some degree, be compensated for.
