I have an 85" TV placed at the back wall in between my speakers.
The speakers however are about 8’ out from that wall and are front ported. There are also 4 subs in the corners along with ASC tube traps.
At first and second reflection points I have Stillpoint Apertures. In front of the TV, I built a stand for 2 more Stillpoint Apertures. The top Aperture has a bracket that slides into the bottom Aperture that can be removed for watching TV, video etc.
Check out my system page, you can see it.
I do think you need to pull your speakers out more into the room so that they are not in the same plane as the TV. Can’t you just pull them out when you listen to music?
