RAISE THE VOLUME
Great point, and in addition to this, make sure that you are selecting the correct type of speaker in your settings (Atmos enabled vs Ceiling speakers). If your AVR allows for it (as my Pioneer SC-99 does), once you select Atmos Enabled speakers in settings, you must also indicate the distance between the speaker and the ceiling. If you do this correctly, when you run the calibration software from the receiver, it will compensate for the additional travel distance (speaker ----> Ceiling ----> main listening position). Even after this is calibrated, the make up of your ceiling (tiles vs sheetrock etc..) can still reduce the quality of the reflected sound, so in this case you would need to increase the overall gain of the Atmos enabled speakers manually by adding another 3-5db if neccessary, as mentioned above. Personally that is what I have done and I love the results.
One other thing... The more comments I read in this forum about Atmos and even DTS:X, the more I feel like some folks might be missing the point of Object based audio. I believe that some are expecting these two new formats to behave like the old channel based audio where a specific sound was intentionally reproduced in a specific channel. So now when folks are listening, they expect the sound to come from specific point above them. In my experience so far, and from what I've seen and heard, the goal of these formats is to create a "seemless' audio transition and atmosphere that will make the use of ALL of the speakers available in your setup. This means that the base layer of "bed speakers" are included in the overall effect.
Before I upgraded my setup from 5.2.2 to 5.2.4, I was able to hear the front effects transitioning to the back of the room because the audio would travel along the speaker path from front to back using a combination of the front LCR speakers the Atmos speaker and the surrounds. after I added the additional rear Atmos Enabled speakers, the sound became fuller and the transition effect was extended because it now also used the back Atmos speakers in the process. I have a very tough room with angled walls/ceilings and only a small amount of flat/horizontal ceiling. I've taken my time to position the speakers so that I get the best overall reflective sound as well as base bed sound. Then I've further tweaked the enabled speakers by raising the gain after the calibration. The end result has been to my satisfaction, and when I play a movie or a demo clip in either Atmos or DSU, the trasition is seemless around the room, and I can sense the sphere of sound that is created around me. It makes the room feel larger as the sound is now more immersive.
