[Why did I put my speakers here....]

Thanks HenrikTJ,  I take nothing harshly when asking for advice.  If I didn't, then I'd not be getting true advice.  I will consider all your information as I'm already in the process of reworking my room !  I will update this post once I have the room re-do complete!  Thanks again for pointing out all the do's/and don't do's ! 

 

 

[Finally hit a wall - can't decide between CDT 5650 C II and CDT 5800 C II]

I have all Klipsch, and I have (6) CDT-5800-C's in my ceiling and love them, they work beyond what I was expecting!  The tilting woofer and the direction horn are awesome for getting the sound where you want it. 

[Why did I put my speakers here....]

Hi everyone, I've been using Klipsch products for around 15 years and love them.  I finally got around to dedicating a room for my home theater and it's working pretty good.  I went for an Atmos 7.1.4 setup.  But I'm not sure I have my speakers identified or placed correctly.  I don't know much about Auro 3D except I think it is not as popular for formats on many DVDs at this point.  I was thinking Auro 3D and was thinking of putting a VOG speaker in the middle of the ceiling, but would rather concentrate on getting Atmos 7.1.4 setup properly.  The image I included shows the general layout of my room.  My TV is a Sony 75" XBR75X900F 4K, my receiver is a Denon AVR-X6400H (no additional amps).  Everything sounds really good as is, or at least I think it does.  For tuning / reference I use the DTS-Dolby & Atmos Reference Blu Ray's from 2016, the Atmos samples seem to place the sounds where I would expect them (at least I think it does) when looking at the visual video reference on my TV.  So I guess my questions is:  is it OK to have the SL/SR, RHL/RHR and SBL/SBR all in the ceiling?  Should I relocate any of these speakers for a better or more proper Atmos experience?  My seating is the Octane Bolt XS-400 recliners and are located about 11 ft from the back wall and they can't be moved forward.  When sitting in my middle recliner I'm roughly 11 ft from the TV display to my nose.  If I relocate the side surrounds to the walls, they would be further out by 6 to 7 feet vs in ceiling where they are located now.  This is the only big change I was thinking could be possible.  Thanks in advance for any guidance you may be able to offer.
