Need some help all. posted in two threads as not sure which was the best for help.. anyways. Theater is underway and drywall going in. Soffit coffered ceiling in. here is the issue. room for dimensions for theater are 20 by 28. this includes the stair case. otherwise 20 by 25 not including stair case into the basement. specs are screen size is 135 to 155" . Yamaha rx-a2040 update firm ware to Dolby Atmos, projector sony 4k projector. speakers are B and W. ccm 663 for ceiling and cwm663 for wall. I had it set up per the recommendations of Yamaha.. left and right and center channel. and in addition front and rear presence speakers. front presence on the wall. back presence in the ceiling. in other words.. a 7.1 system with additional front and back presence. looking further at dolby atmos. I think it makes for sense to do a dolby atmos layout. so the first question is 1. choose dolby atmos layout over the Yamaha suggested front and rear presence additional speakers. 2. question. my back wall is not a single wall to say because of stair case. so I am looking for suggestions .. do I want to 1. put the speakers in the back wall over the ceiling for rear surround sound? 2. if the walls are an option in back do I put them both right and left and the very back wall or can ..do I put one on the stair wall and the other on the back wall .. I know it sounds confusing but here are some pics. drawing is a little messy .. help is greatly appreciated.. forgot to add... or does it make sense to simply do the back surrounds in the ceiling instead of wall.. but then the sound is coming from above?
Yamaha makes receivers
Dobly developed the concept and makes the gear that movie studios use to mix and publish 5.1. 7.1 and Atmos sound track based movies. Who are you going to listen to for advice on setting up your speakers?
actually it was a calculated known wife error if you get what I mean.. I was overruled on that request to close it up.. that and the side left wall to the rest of the basement.. then again.. it still rocks pretty nicely so far.. but yes message received.. these are the cards I now have in my hand.. any help appreciated..
to funny... putting the Rear surround sounds in the black box option in the photos. so basically hoping the rx-a2040 will compensate during set up for the distance differential of 30 inches. posted some other issue on confusion on placement of surround side speakers.. Yamaha says when doing the four ceiling atmos speakers to place the side surrounds behind the back ceiling speakers. Dolby says no they stay in middle.. snip pics below explain it a little better than I do.
Dobly developed Atmos and I've seen that chart in their dealer and installer training materials, does Yamaha know better? or just the limitations of their receivers. Dolby also recommends that the fronts, sides and rears be basically at ear level, higher on the sides and rears if necessary to clear seat backs and adjacent bodies. Both of those diagrams are for a single row of seating.
ok so if the future plan was to put in a second row would you suggest the higher position for the rear surround i.e red boxes on back wall nothwithstanding the stair spindles in front.. 6 one way 1/2 a dozen another. thankyou
