5.1.4 Atmos and Surround Speaker Placement Recommendations...
I plan on using 4 Klipsch RP-500SA "elevation" speakers mounted at the top of the wall in a Top Middle/Rear Height or Top Front/Top Rear configuration. I've shifted my sofa as far as I can towards the left side (right side as you view the pictures) since there is a storage room to the left of my front sound stage. Despite having to justify the main listening position towards the right side of the room, I've decided it's probably best to center the Rear Atmos speakers with the room as opposed to the seating.
My first question is how far apart should the Rear Atmos speakers be? I know Dolby recommends they be placed in line with the L/R speakers, but with the shift in my room, the Right Rear Atmos speaker would be too close to the wall by the curtain. I've read that 1/6 in from the side walls is recommended, and that's where I currently have the tape. The back wall is 12 ft. wide, so the tape marks are 2 ft. in from the side walls. With this placement, the Left Rear Atmos speaker is actually close to being in line with the Left speaker up front. I've also read recommendations for 1/3 in from the side walls. However, that seems like they'd be too close together, losing any separation effect and also making them even further from the original Dolby recommendations. Does anyone have any suggestions given my specific setup?
My second question is regarding my side surrounds. They are Klipsch RP-402S bipole speakers and since I'm centering the Atmos speakers to the room and not the off-center seating, would it make sense to position the surrounds the same way (Picture 1)? Since they are on stands, I could easily have the surrounds equidistant from either side of the seats (Picture 2). Would it be preferred to have the distance match on either side, or would the setup in Picture 1 be just as effective after room correction (Audyssey) is performed?
Thanks in advance for any advice as I finalize the placement of all of my rear speakers.
