How to Setup Your Room for Atmos and Immersive Audio

I think this video by the Dolby Institute is targeted at professionals but the principals translate to the home. You’ll notice that they don’t use the ceiling speakers pointing straight down but bookshelves that are angled toward the MLP. The other thing you’ll notice is that all of the bed channel speakers are at the same height (that includes the center channel). At 16:00 minute in the video make sure to watch the part about room tuning, very helpful as to what DSP can and cannot do:

" I feel like money spent on this type of help (room treatments and acoustics) will be more valuable than any piece of gear you will ever buy"




My room has no parallel walls only the floor and ceiling.

OK, do you have any room measurements yet? How will you apply room correction to your 5.1 setup?

The reason I posted those links above is the panels are portable. With the ASC or Auralex solutions you could have any "walls" (like the Attack Wall") you want.

You talked about acoustics, the reps of these companies help you setup as part of their service.

So, can you post some measurements?



if I get to excited about mixing for the rears and the tops my mix won't translate like it should back to 5.1 or stereo

I guess you know your client base and until someone asks for an Atmos mix no need to go there. Better to setup your 5.1 setup just right first.


And treatment for your HT need not be ugly. I went with Auralex because I love bamboo. All of those wooden diffusors you see in my pics are made from sustainable bamboo. It sounded better than fiberglass diffusors in my room. There are plenty of vendors to suit your taste, ASC stuff looks great and is very functional. If you get an Attack Wall the same company could treat both spaces:


here is the hot tip for the most advanced information on multi-channel speaker positioning from the world’s leader on this subject. when i was positioning my own 9.3.6 multichannel set-up, i choose the Trinnov approach instead of the Dolby Atmos approach for my ceiling after much research.

looks like the link to the pdf does not work properly. so google "Trinnov Multichannel playbook", scroll down to "Loudspeaker Position Guide -AVS Forum", then select to get the download of the PDF, then open the PDF.



Thanks @mikelavigne , I got it. I like this better than the guide Dolby puts out, more detailed. I was watching an interview of Peter Lyngdorf who felt the ideal number of speakers in a HT was less than 16, I think he felt the max he says you should do was around 12. I am very glad I saw that video because it saved me $$$ on upgrading to one of the 16 channel processors. The best resource I found for listening to MCH music was Tomlinson Holman’s research when he was working with Audyssey. They found that wide channels were more important than rear surrounds or height channels. (see page 23 in the Trinnov Guide linked below) I A/B with and without wide channels and find his research to be spot on. This link might work:
