I searched all around to get ideas for my particular setup, but couldn't find many options where the couch is against the back corner wall and there's a large space where a side wall would normally be in a rectangular room. I can do either a 5.1.4, 7.1.4, or even a 9.1.4 setup with Atmos/Auro 3D and "Voice of God" Channel. Definitely welcome the feedback. Wife comes home in 2 weeks, so the time is now. (Apologies in advance for any typos. Doing this off my phone.) Adding a floorplan with measurements in case it helps. What I'm comfortable with so far: Fronts: SVS Ultra bookshelves for the FR and FL and a SVS Ultra Center. Atmos: 2 rear heights above couch facing the front, 2 front heights above FR and FL bookshelves facing the rear. (Left and Right front and rear heights would be aligned.) A Prime Elevation for the "Voice of God" channel above and slightly in front of the MLP. QUESTION: What to do with the rear and/or side surrounds? I'll probably use all SVS Prime Elevations or a combination of Prime Elevations and SVS Surrounds (Bipole/Dipole/Duet mode). I had some ideas I wanted to bounce around with the group: a) Prime Elevations mounted on the back wall, both about 2' above the MLP (main listening position), either: a1) mounted horizontally, angled inwards to direct the sound more towards the middle of the room; a2) same as a1, but angled outward, away from the middle of the room to spread out the sound; a3) same as a1, but angled 45° down and more directly, albeit not too directly, to the MLP; or a4) angled to fire up to the ceiling, something recommended by Zeos (Z Reviews: 34:30 mark) b) Ceiling mounted, one on each side of the couch, both angled towards the MLP. 1 on side wall and 1 on the other side of the couch, but up against the back wall. ISSUE: Higher than recommended, but assume Audyssey MultEQ XT32 calibration can help with that. c) SVS Surrounds on the back wall, about 2' above th MLP, in either bipole or Duet modes. ISSUE: one of them would be in a corner pretty close to the corner and right above one of the seating areas. d) any of the combination above for more of a 7.1.4 or 9.1.4 setup.
