econav Posted July 11, 2014 Posted July 11, 2014 Too late for me then. nothing is too late , if the ceiling already there , first identfly the problem , frame work or control relfection ? then apply the needed step to reinforce the ceiling or adds ..........
francis wu Posted July 12, 2014 Posted July 12, 2014 Interesting! :) Good, I have 4 of this in my store room now and these will be my Atmos speakers in the future ;D
petetherock Posted July 18, 2014 Author Posted July 18, 2014 An article on Atmos enabled speakers: http://www.audioholics.com/audio-technologies/steerable-dolby-atmos-speaker-proposal Option #1: Ceiling mounted speakers firing down at the listening area Option #2: “Atmos Enabled” speakers with top-firing drivers that bounce the reflected sound off the ceiling to the listening area Option #3: Steerable (pointable), wall-mountable “Atmos Enabled” speakers
petetherock Posted July 27, 2014 Author Posted July 27, 2014 http://www.audioholics.com/audio-technologies/steerable-dolby-atmos-speaker-proposal Some ideas on speaker design and placement.. alt=Dolby Atmos Ceiling Diagramhttp://www.audioholics.com/audio-technologies/steerable-dolby-atmos-speaker-proposal/dolbyceiling.jpg/image_preview[/img] This still seems to be the most ideal, although it requires some carpentry or work to be done on the ceiling...
desray Posted July 27, 2014 Posted July 27, 2014 This is what happen if we decide to do ceiling speakers... Yikes...
petetherock Posted July 27, 2014 Author Posted July 27, 2014 IMO, there may be real interference from each speaker due to their proximity...
Doggie Howser Posted July 27, 2014 Posted July 27, 2014 IMO, there may be real interference from each speaker due to their proximity... also to listening position v the side wall reflections
desray Posted July 28, 2014 Posted July 28, 2014 Here comes the question of speaker placement and the room mode. Will small room yield any benefit even if the use go for full dolby atmos setup with sat a 5.1.4 array vs a larger listening room.... How will the reflection and interaction of the sound waves between the two rooms react... For me, if room too small, dolby atmos will not work at its best simply because the speakers are located too near to each other to allow one to distinctly make up the object based panning sound whereas for a larger viewing space, it will provide more space for the sound energy to dissipate and thus making it more wider and bigger.
tane0019 Posted July 28, 2014 Posted July 28, 2014 Think for a small room, go for 5.1.2. LCR + Rear LR + 2 ceiling should be enough.
petetherock Posted July 28, 2014 Author Posted July 28, 2014 Suggested speaker positions from Dolby: http://www.dolby.com/in/en/guide/dolby-atmos-speaker-setup/index.html 7.1.4: http://www.dolby.com/in/en/guide/dolby-atmos-speaker-setup/7-1-4-setups.html 5.1.2: http://www.dolby.com/in/en/guide/dolby-atmos-speaker-setup/5-1-2-setups.html
petetherock Posted August 7, 2014 Author Posted August 7, 2014 My efforts to integrate the ceiling speakers into my existing false ceiling seem to have hit a snafu.. my contractor says it will be hard :( Hope Nic finds a solution. Right now, I am looking at the A'Dia AG speakers for both my place and mum's..
petetherock Posted August 10, 2014 Author Posted August 10, 2014 Some info from the HKG show: http://www.feversound1.com/140809-atmos/ The ceiling speakers are behind and in front of the main listening position... I think to fit the ceiling speakers in the centre of the ceiling will be quite challenging for those who are looking to retrofit them in to current setups without some major hacking... Not too WAF friendly I am afraid... height=600 width=900https://farm4.staticflickr.com/3904/14674565120_661216c699_b.jpg[/img]

Wilber Posted August 11, 2014 Posted August 11, 2014 guys, which way do you prefer? the green one is for atmos. need suggestion, installing tomorrow.
petetherock Posted August 12, 2014 Author Posted August 12, 2014 Bro Wilber When you use the term "which one" I assume you will be giving us choices to help your selection process? I don't see the various choices? Anyway for bros entering the Atmos world, I must first profess that I am also new at this. So my personal advice is to build in some flexibility, or delay your building until more info is out. The previous diagram I posted gives the suggested angle from front to back, but it doesn't say how far from the sides. So I would prefer to see the first few amps, and the way the makers suggest speaker placement before I leap in. Of course if you are in the process of renovation, then you may have to do it now. But if you add a banana wall socket, and allow some flexibility, you may be better off. Cheers
Wilber Posted August 12, 2014 Posted August 12, 2014 Oh, the picture disappear, let me fix it later.. anyway left side is typical cinema setup, right side is 45 degrees aiming at sweet spot.
Wilber Posted August 12, 2014 Posted August 12, 2014 The information right now is still vague. They're installing later.. time is running out for me
Wilber Posted August 12, 2014 Posted August 12, 2014 alright, installation delayed... contractor mia.. that gives me more time to consider..
petetherock Posted August 12, 2014 Author Posted August 12, 2014 It's a brave new world, my own renovations begin soon, but I might bite the bullet... That means cutting a track in the ceiling to allow the placement of the ceiling speakers more centrally, centering in a rectangle around the top of my listening position.. And for my mum's new place, that may warrant a total ceiling re-design in order to accommodate the new placements.. I think the old idea of placing them just above the side walls or in the cove lights is the wrong position... It's an interesting year, as we make adjustments to traditional ideas of speaker placement that have dominated our HT rooms for at least 2 decades...
Wilber Posted August 12, 2014 Posted August 12, 2014 yes, redesign to accommodate would be best! your place compromise a bit for the speakers would be more ideally. ya, placing on the side corner is wrong definitely.
Wilber Posted August 12, 2014 Posted August 12, 2014 wilber, what speakers are u using for ceiling ? JBL 8320
petetherock Posted August 13, 2014 Author Posted August 13, 2014 This is a statement I got off AVS about speaker placement: 3rd white paper coming out that is intended as an installation guide with best practices for custom installers (and the rest of us) that Dolby intends to release at CEDIA. Personally, I would hold off on mounting any speakers until I've at least perused that white paper. At that point, I would decide how closely I want to stick to their recommendations.
