Rear speaker placement and Atmos issue

Redoing the living room and wanting to go with Atmos 5.1.2. Pic 1 shows where the tv will be. The sectional will be in the corner in pic 2. Pic 3 shows another view of the back wall.

A have a couple of questions related to speaker placement.

1. In Pic 3, thinking of using some polk audio fxi a4 directly behind where the sectional will be on the back wall (See mock up). Would this be a good placement?

2. For the overhead Atoms speakers the ceiling is slanted. Would it be best to move them to the area that is flat? The speakers won't be directly overhead but in front of the couch. Or do they make some sort of back angling speak to fire towards my seated location?

Sorry for the crude mock up but the recommendations I got for my center channel were outstanding. Thanks in advance.

You're going 45 degree diagonal for TV and speaker placement???

It's a VIRTUAL channel unless stated otherwise.

The plan is to wall mount the TV centered on the wall where the stand is currently sitting. The sectional will be in the corner across from it.

You do not want to mount any of your bed speakers higher than half way up a wall, per Dolby spec. The Atmos speakers need to be in front and behind the seating area, so you would need to pull the sectional out from the back wall (this will help with the surround issue, as well).

There are some speakers with built-in angles, such as the RSL C34. However, the slant does not appear to be enough to worry about it.

Moving the couch away from the wall and corner isn't an option (wife). Would it be best to use bipoles on the rear wall just to the left and right of my seated position? Or monopoles angling in, mounted on the rear walls in the same spot?

My mockup is in the last pic. I was thinking of placing the in-ceiling ATMOS speakers further towards the middle of the room for more spaciousness.

You'd probably be better off with front and rear height speakers as your "Atmos" than doing what you described. This places two of the four speakers at the top of the front wall, facing forward and downward, and two at the top of the rear wall in the same configuration. Get white speakers, so they blend with the wall. Small speakers, like Gallo A'diva, Cambridge Audio Minx Min, Polk OWM3, KEF T101, Monitor Audio Radius 45 .. would be good options. Avoid big-box speakers as they would not be aesthetically pleasing.

As to the rear speakers, given the layout, everything will be a compromise of some sort. You might try the di/bi-pole option placed against the rear wall, above seated ear level but below halfway up the wall. Another option would be to get regular speakers, placed similarly, but toed-in at a 45 degree angle. Either approach may or may not work (have a return window available).
