    Great video. I like Audio Advice's method as it puts the 4 atmos speakers in a square pattern with the main listening position in the center of that square. Hence the angle from your head to each speaker should be the same (45 degrees). This is perfect for the main listening position. But, I'm thinking for the other seating positions it won't sound quite as good as if the left and right were spaced further apart.

      Thank you. Yes, maybe that’s why Dolby spaces them and in line with the fronts. But in my room having them spaced out does sound better and works for the extreme left and right seats.

    knowledge changes if you ever add a 3rd set of atmos speakers install in-between in a bit closer together. I have mine installed the way dolby originally said in line with front as well. My spacing front to back was about 45 degrees in each position when I had 4. i upgraded to a Denon 3800H which let me run 3 sets of ceiling speakers looks like you have a 7.1 base but eventually 3 sets of overheads will become more mainstream set up. nice room by the way

      That’s nice. I have a 7.2.6. I have front heights and use the top fronts as top middles along with rear heights. I repurposed the top rear to rear height since they are so close to the back wall. But I do have connections on the top of the rear wall for proper rear height installation

    It’s kind of funny that Dolby’s own guideline is being proven to not be the best. I too followed the guideline and have regrets now. I also think on ceiling speakers with adjustable mounts are probably better than in ceilings as you can make sure the speakers are aiming on axis to the MLP. Good video

      To avoid all the angles and pointing to main listening position, in my opinion it is better to simply go with Front and Rear heights or Front/Rear heights plus Top middle (which can double down as VOG as well).

    • @magnoliamo
      @magnoliamo  10 місяців тому +1

      So that’s not a Dolby Atmos specified configuration. Your processor will not allow you to have a top front and top middle configuration. You will have to select top front and top rear but that will move the 3D bubble in front of you as opposed to being in the front and rear with you in the middle. I suggest going with front and rear heights with top middle or just top middle. The other option would be to go with the auro 3D layout of front height and side heights which are inline with the top middle but above your side surrounds and to the sides.

    Great video Mo. My top speakers are set the way Dolby shows on their website, which is not the best position if you want good Atmos immersion as it doesn't give you enough separation between the bed layer and the tops. HT Gurus explains it well in his videos, IIRC the tops should be approximately 0.5 to 0.7 the width of the mains.

    The Audio Advice recommendations mention distance of screen to front of first seating row - this is highly ambiguous. Do they mean to the front of the seats? This is not a reference point of any value as the actual head and listening position will depend on the design of the seats. Why don’t they just reference the actual listening position?

    Absolutely not!
    You have 6 heights. If you only had 4 heights, with no intention of upgrading to 6, then yes, a 45° to 55° position would be reasonable. But with 6, 30/90/150 is WAY better. Especially if you make use of Auro3D and DTS:X as well as Atmos.
    DONT DO IT!
    Keep in mind Mo, people talk about "separation" an awful lot, but in reality, most sound objects are attempting to rended in-between layers.
    Remember Wilfried von Balen and Kimio Hamasaki's research conclusions: when the angle of the height speaker is too great, vertical imaging collapses to the closer or the louder speaker.
    THAT is why people like the higher angle.....its closer and the sound COLLAPSES to the height layer and sounds like its coming from above and impresses people. When in reality, the sound should image between layers. Those with heights between 30° and 45° can actually image objects between layers.

      @@magnoliamo @magnoliamo thanks Mo. I'm just one of those types of nerds who does a ton of research on stuff. Then I try to put what I learned into practice to see how well it worked. You seem to do the same kind of thing. Thats what put you on the right path.
      A lot of the installers and professionals came up with their methodology in the early days of Atmos when a 7.1.4 setup was considered the pinnacle of Atmos. (LOL. Its always been possible to set up a 24.1.10 if you had enough money) and many people just randomly installed in-ceiling channels to have Atmos. Most of these people ended up having a lackluster experience. Mostly due to the fact that their in-ceiling speakers didnt have enough baffle angle and were horribly off axis. So they started bringing the upper channels closer together (i.e. on-axis) and had a better experience. So in their mind, that was the answer. Closer angles were better for Atmos.
      Meanwhile. Those of is who put bookshelf speakers on the wall or ceiling and aimed them at our listening positions were having a great experience the entire time. Didnt matter if it was 30°, 45°, or 60°, it sounded great, because our upper layer was on-axis.
      The one thing people discovered was that if you opted for 30° heights, its best if you have a Top-Middle or Voice of God at 90° to supplement sounds originating from above. What people didnt realize is that Top-Middle speaker, paired with Side Surrounds at 90/270 gave the absolute best 3D immersive effect.
      I've tested it personally and the best 3D effect is with that specific configuration.

      I recently moved my surrounds from about 120° to 90° after reading the NHK 22.2 research just to test how it would be and the difference was stark. Thats where the best, most tangible 3D images were delivered.
      Then I realized that whenever my system sounded its best, it was always wh my surrounds at 90° and my Top-Middle around 90° elevation. Whenever I moved one or the other, I would lose a significant amount of immersion.
      Thats when the research made sense to me. It was the ability to accurately track imaging from the sides causing this.
