spells Posted December 12, 2014 Posted December 12, 2014 Power is cheap... 4 ceiling speakers spreads the sound nicely.. If you don't believe that bring your 4100 over and we can use it with my Atmos setup... Even an old AV amp with 7.1 inputs will work.. but how well and the sound... YMMV.... bro your set up all professional type, skali hear liao no matter how i setup also cannot come close to yours than i will be vey disappointed. hahaha
Yummyyumi Posted December 13, 2014 Posted December 13, 2014 I bought the emotiva xpa 3 to power my LCR (B&W) and the pioneer LX58 AVR (upgraded to Amos) to power the sub and surround (Tannoy) and TOP FRONT (Anthony Gallo). So it's 5.1.2. I got extra 2 x anthony gallo sitting and unpack waiting to integrate to my 5.1.4... Just need to get approval from my Mrs first on the drilling and exposed wiring to install ok the TOP REAR. Thanks Pete for the error. Sent from my iPad using Tapatalk
petetherock Posted December 13, 2014 Author Posted December 13, 2014 Just sharing some terms to avoid confusion: Front Heights : used in DTS Neo X, the legacy DPLLz and Audyssey DSX Front Wides are used in DTS Neo X and Audyssey DSX Top Front, Top Middle and Top Rears are used for the ceiling speakers in Atmos VOG : Voice of God in the middle above the MLP for Auro Front Heights, Side Height, and Rear Heights are terms used in Auro... http://www.datasatdigital.com/docs/archive/speaker-tech-guide.pdf

Yummyyumi Posted December 14, 2014 Posted December 14, 2014 bro how much for the emotiva xpa 3, you also stay in pasir ris ? Hi spell. Yes I stay in PSR as well. Bought at USD 799 before less 10%. Should have gotten the XPA 5 instead... If I needed the extra 2 channel... It's there.. Sent from my iPad using Tapatalk
petetherock Posted December 14, 2014 Author Posted December 14, 2014 Atmos is a real bonus for sales .. More speakers, amplifiers and miles of cables :)
AB Chan Posted December 17, 2014 Posted December 17, 2014 Just come to know JBL has a "professionally calibrated" 7.2.4 Dolby Atmos system setup available for audition now at their showroom at #02-17/18 Raffles Hotel Shopping Arcade, North Bridge Rd. Just wondering how a "professionally calibrated" system would sound like. Anyone been there?
dannyhgt Posted December 21, 2014 Posted December 21, 2014 More or less pulling trigger on Speakercraft soon. There are so many models to choose from ???... For Atmos setup for only one golden seat, is it better to have 4 X Aim series speakers tilting towards the MLP, or to get 4 X Aim Wide speakers to achieve wide dispersion effect? http://www.speakercraft.com/products/architectural-speakers/in-ceiling/aim-wide?page=shop.product_details&flypage=flypage_sc.tpl&product_id=45&category_id=41
AB Chan Posted December 21, 2014 Posted December 21, 2014 How much are those speakercraft aim-wide speakers? According to Dolby, ceiling speakers with wide dispersion angle of 90 deg (45 deg from vertical) or more from 100-10KHz can point straight down. If dispersion is narrow, angle them or use models with adjustable angle tweeters. However, I guess this is only a guideline and would depend on your MLP and the location and distance between the ceiling speakers.

Some models of in ceiling speakers can do that.. Also, that will help if you move the MLP..
dannyhgt Posted December 22, 2014 Posted December 22, 2014 How much are those speakercraft aim-wide speakers? About US$200 from various sellers in Amazon...
whitesox Posted December 23, 2014 Posted December 23, 2014 I intend (plan) to setup 7.2.1 in near future (maybe early next year). so when read this website: http://www.dolby.com/us/en/guide/dolby-atmos-speaker-setup/7-1-2-setups.html There are 3 positions for ceiling surround (65, 80 and 100) deg I wonder how to measure and which one should I follow? I thought exactly above listening position is zero deg? hear your advise soon
petetherock Posted December 23, 2014 Author Posted December 23, 2014 The rule of thumb for ceiling speakers is to be between 35 to 55 degrees from the perpendicular. I am assuming you are installing Top Middle speakers for a 7.2.1 system? Then they should be pretty close to the perpendicular, i.e. above your MLP.
Guest CASH Posted December 23, 2014 Posted December 23, 2014 I will show u how i do it once i am back in singapore tonite. I will take pictures n post it here. pretty simple procedure..

Then they should be pretty close to the perpendicular, i.e. above your MLP. yap.. Surely left and right ceiling spk must be in line but... Err... what is MLP? ??? Currently, all my surround speakers are mounted on the wall 180cm up from the laminated floor and all of them are tilted down 30 deg. Since I want to adopt ceiling surround meaning all back and middle surround height must be even lower huh?

MLP = Main Listening Position For a totally immersive experience, the 7.1 surrounds should be around your ear level when you are seated. Then the Atmos speakers form a higher level of sound immersion.
Guest CASH Posted December 23, 2014 Posted December 23, 2014 I will show u how i do it once i am back in singapore tonite. I will take pictures n post it here. pretty simple procedure.. as promised, these is how i did my setup of atmos speakers.. pictures in next post.. of course u need to do it for the left n right positions above your front left n front right speakers.
Guest CASH Posted December 23, 2014 Posted December 23, 2014 1) for getting the angle right!! 2) level meter to keep it perpendicular.. 3) metal measuring tape extended to point to ceiling spot to drill. thats all thats needed.
francis wu Posted December 23, 2014 Posted December 23, 2014 Frankly, I don't get what you are trying to show! Sorry ??? ::) :)

petetherock Posted December 23, 2014 Author Posted December 23, 2014 My installer used one of these : http://www.boschtools.com/Products/Tools/Pages/BoschProductDetail.aspx?pid=GLM%2080
Guest CASH Posted December 23, 2014 Posted December 23, 2014 yes, laser pointer is very accurate. but i jus like to tinker with what i have at home. its very cumbersome n tiring to use my method too, but, hell... i enjoyed every minute of it! jus looking at my own work done gives me satisfaction that i can still do these stuff. because when i get really old n eyesight fails, muscle degenarate n all that stuff with old age, i can enjoy what i can do now. must learn to relish my whatever youth left in me. hehehehe! ;) ;) ;) ;)

petetherock Posted January 1, 2015 Author Posted January 1, 2015 Another entry into ceiling mounted speakers for Atmos: http://www.kef.com/html/gb/showroom/custom_installed_speakers/ci_series/speaker/Ci200RR/index.html The parts in red and bold will apply to most ceiling mounted speakers... By Essential Install Editors, May 01, 2014 Q. What do you feel are the key features that differentiate the Ci200RR-THX from other in-ceiling units on the marketplace? Dr. Jack Oclee-Brown: The Ci200RR-THX is based around our latest Uni-Q driver technology. The Uni-Q uses a tweeter placed at the acoustic centre of the bass/midrange driver. Using this configuration we can make both the acoustic centre and the dispersion of the tweeter and woofer appear the same. The result is that once you add a crossover, it is almost impossible to tell that the sound is coming from two drivers. Normal systems suffer from interference because of the two separated drivers. For a ceiling speaker this is particularly important because of the orientation of the speaker. For use in a home theatre, the Ci200RR-THX should be placed in the ceiling as close to the point above the front edge of the screen as possible, because of the wide off axis response, it will sound like the audio is coming from the screen. While this is true for all KEF Uni-Q speakers, with the Ci200RR-THX, special attention has been paid so that this is effective even in the largest theatre rooms. Q. The ‘sweet spot’ of listening with the Ci200RR-THX is billed as very wide– how has this been managed? A. With a traditional loudspeaker the sound becomes very directional at the crossover between the tweeter and the woofer. With a Uni-Q this problem is eliminated. In addition, the Ci200RR-THX utilises a large 1.5in tweeter with one of our most recent ‘tangerine’ waveguide designs which helps to keep the dispersion of the treble very wide. Overall the dispersion is more consistent than a traditional loudspeaker, which means that you get good sound over a wider coverage area. Q. What challenges were there in attaining THX ULTRA2 certification? A. One of the most challenging parts of the ULTRA2 certification is the output level requirement. THX specifies a high maximum output level that can be quite tricky to achieve. In the Ci200RR-THX the large tweeter and the large voice coil on the woofer help us to hit this specification. Both of these features are also critical in achieving low levels of dynamic compression. Q. Why is THX ULTRA2 Certification important for KEF? A. KEF spent significant engineering and monetary resources, to design and build a speaker capable of being used as a LCR in very large theatre rooms - where the viewing distance could be greater than 4 meters and the cubic volume could be over 85m3 (3000ft3). This also required more expense on a larger motor structure (magnet) than is found in the typical in-ceiling speaker. Being one of the few in-ceiling speakers to achieve THX ULTRA2 Certification reinforces this point, and gives the end-user comfort in knowing their theatre will exceed expectations. Q. How easy is the speaker to install? A. The Ci200RR-THX uses KEF’s UTB (Ultra-Thin Bezel) and magnetic grille. So all you see around the grille is a very thin white bezel edge that can be painted to match the ceiling colour. Once the hole has been cut and the wire run to the location, installation of the speaker takes less than two minutes. All it takes is tightening four dog-leg mounting screws and then the grille magnetically snaps into place. Q. Can an in-ceiling speaker ever be as good as free-stander? A. The latest in-ceiling loudspeakers are extremely good and can offer performance that is, in many cases, as good as equivalently priced floor-standing loudspeakers. Acoustically there are advantages in both types of design. For example, with a floor-standing loudspeaker it is normally the case that the physical position will be better, most likely it will be placed directly in-front of the listener. On the other hand, an in-wall or in-ceiling mounting results in a better acoustic loading for the driver. However, the installation is absolutely critical to getting the best performance from a wall mounted loudspeaker. It is important that the walls and ceilings are built as sturdily as possible to avoid vibration, and that the rear cavities behind the loudspeakers are well proportioned and filled with acoustical damping material. For ideal bass response with the Ci200RR-THX, we recommend a rear volume of 20 litres or more, but it can be used in cavities as small as 10 litres. The Ci200RR-THX
