I decided to use this old thread instead of starting another Atmos related thread, to keet the forum a bit "cleaner".
I bough a pair of R-41sa and hooked them up a few days ago and now I'm running 5.1.2.
My HT room is 16 x 13' with 8' ceiling. MLP is almost in the middle of the room, 4' away from the back wall. After reading recommendations for Dolby Atmos guidelines, due to my 8' ceiling I went with Atmos enabled set up. My R-41's are sitting on top of RF-82's apprx. 11-12 ' away from MLP.
I've tried to google for information on now much reflected from the ceiling sound waves are getting disperse, but can't find any data or formula oh how to calculate the bestMLP location based on distance from Atmos enabled speakers in relation to the ceiling height.
Do I need to move my MLP forward or it's right where it need to be to get reflected from the ceiling sound waves?
Audyssey calibration measurements:
Front R - 11.7', - 4.5db
Front L - 12' , -6.5db
Center - 11.2', -7db
Sub - 13.1', -9db
Sur R - 6.7', -3.5db - adjusted to -2.5db
Sur L - 6.6', -4db - adjusted to -3
Front Atmos R - 11', +1db - adjusted to +3
Front Atmos L - 12.2', +2db - adjusted to +4
I've added 2 db to both Atmos channels to make them more audible, as far I've read a lot of people are doing +2db for Atmos up-firing and down-firing speakers.
So, despite following statements
"Will I always get better Dolby Atmos sound with overhead speakers?"
"Dolby Atmos enabled speakers produce slightly diffuse overhead audio that is quite lifelike and, in some cases, preferable to the sound that comes from overhead speakers."
"Audio experts agree that the overhead layer of sound produced by Dolby Atmos enabled speakers can be preferable to the sound originating from overhead speakers."
"Dolby Atmos enabled speakers do not rely on virtualized processing. That means you don’t have to sit in a specific spot to get the full Dolby Atmos effect."
"Based on an understanding of how the brain interprets sound, Dolby Atmos enabled speakers modify select audio frequencies to reinforce the sense of sound coming from above. This filtering is also applied to any sound that may leak horizontally from the speaker cabinet to further amplify the perception of sound coming from above."
Do I need to increase the distance from Atmos speakers to MLP since the sound has to travel up to the ceiling and then down to MLP?
We've watched a few movies and we sure feel the difference of 5.1.2 vs 5.1 , but I want to be sure that I'm getting the best possible sound from my current set up.
