I’m hearing some pretty full range effects sent to the Atmos speakers, and I can only imagine sound mixers will continue to use them more aggressively as time goes on. 1.) For example, extrapolate the front row angle to the ceiling speakers to an imposed slope above your example drawing? The problem with the Monoprice speakers (and frankly, most in-wall and in-ceiling speakers) is their dispersion isn't specified. It won’t matter if the timbre matching is perfect if you don’t have sufficient angular separation to the sides and rears for the Atmos effects to be localized as the director intended. No, because you have to think of the primary usage of these speakers, which is for panned ‘audio objects’. We will, room dependent, sometimes add a third ceiling row and adjust the angles of all three ceiling rows to provide even coverage. 1. https://www.cnet.com/news/attention-home-theater-shoppers-think-twice-before-buying-a-center-channel-speaker/ The side surrounds are Polk RT2000p speakers. 3) is the system properly calibrated? Some say that the typical horizontal woofer/tweeter/woofer center speaker design is a flawed concept (see reference #1 and #2 below). I would not do a floorstander on it’s side as that will have the same issues as a MTM design. Well-balanced sound can be … Tweeter down would basically make it like an inverted bookshelf, but also be hanging down from the ceiling further than a “side” angle which would be, obviously, like a bookshelf on its side (tweeter next to the woofer instead of above it), but wouldn’t hang down as far since it would be hanging from its long edge and not short edge of the speaker. Timbral matching. 2. agree that the best approach is a timbre matched set of LCRs. 9 foot 6 inch ceiling. 2) then determining the coverage angle required for the speakers Hi Nyal.

Has the CEDIA white paper on spatial audio layout been published yet? Thanks for reading! Any suggestions would be much appreciated. If you read the Dolby Atmos home theater paper, it states that ceiling speakers should have a 90 degree dispersion pattern out to 10khz. As the room gets lower the coverage requirements increase. Our approach is in line with what is being practiced by other designers and what CEDIA will be releasing in their upcoming spatial audio layout white paper. However, the slope of the ceiling concerns me. My couch setup is probably 17 feet across. Personally I’d rather do the former approach, especially if my second row wouldn’t be used that much. So my biggest dilemmas are the rear surrounds being positioned right behind the couch and WHERE SHOULD I installed the 4 ceiling speakers? First let’s see what losing a foot in room height means for coverage in the case of the speakers pointing straight down. room is a box 15×18 x7. Always lay out the surround speakers with respect to the MLP! I am in the planing phase for construction new house. Very informative article, this given me some lights on setting up 2 row seating. My personally an adherent to well done constant directivity designs (Which Keeles CBT approach includes) and use Gedlee speakers myself. On a side note – the MS05s are currently in Auro 3-D location (front height and surround height – I don’t have Auro-3d AVR though – just Atmos). Paintable to match the ceiling surface. You want localization with Atmos and DTS.X! It’s hard to say exactly what the issue is with your particular setup, because if it’s done right you should feel like you are in a “bubble of sound”. We are building a new house and my TV room area is 15×19, with back area open to the kitchen. But, I think that ceiling mounted would be better all other things being equal. I am installing my setup in a larger room. Most speakers (with exception of some coaxials) have a suckout somewhere off axis due to path length differences between the tweeter and midrange drivers. I do not think a 1′ deep, 5′ wide soffit is something to really worry about, and you’d certainly not see much if any “boundary gain”. I’d be surprised if the Revel you referred to is a good timbre match to the horn speakers, due to totally different drivers and dispersion patterns…. Also, am I correct in assuming that I do not need to also angle the bass drivers since bass is non-directional? Earlier in the comments you indicated one should have at least 15 degree horizontal separation between surround speakers and top-back in-ceiling speakers. The viewing area in front of the TV will only be one couch and maybe a chair. In most theaters if you put the rear ceiling speakers behind the second row of seats then they would be too close (in an angular sense) to the rear surrounds. Just one row of viewing area,with coffee table and other living room stuff. Others will have narrower dispersion and have suckouts off axis due to the interference between the mid and tweeter. Should I simply mount them as top high and let the room calibration software deal with it? Programing front high and rear high? Eggers suggests dealers run the Auto EQ to match with forward-firing speakers in case there are ceiling losses. The soffit is 1′ tall/deep (from the ceiling) and 5′ wide. Installation Speaker. The room is not long enough for two rows of recliners. Now let’s see what happens with angled speakers and lower ceilings. Installation Speaker. Seems like it would make sense to use based on this article. 1) are all the speakers in the right place? But, working with 30,000 watts in an arena is not the same as home audio like this. CEDIA’s forthcoming recommended speaker layouts for immersive audio which was created by a working group of top theater designers, manufacturers and integrators does not implement either the “Atmos Box” or “surrounds at ear height”…you’ll also find that Dolby at the moment do not produce any layout guidance for multi-row, tiered seating home theaters. All this goes to show that a very critical part of any home theater design is ensuring the speakers selected can provide consistent coverage of the seating area. The coverage of the second ceiling row will become the limiting factor in a two row home theater. Normally a vertically stacked driver configuration (tweeter over mid-woofer) has wide horizontal dispersion and narrrower vertical dispersion, and there are often suckouts in the vertical plane. I program them as dolby overheads and still don’t get immersed. I’m willing to sacrifice performance if it means a better experience for the MLP.

The Atlas Sound FAP42T Strategy II Series 4" in-ceiling coaxial loudspeaker combines superior coaxial loudspeaker performance with wide dispersion and easy installation. Speakers with pivoting tweeters seem to need less depth for the ceiling cut-out than those which rotate the entire speaker.

The theatre is currently under construction, elevation speakers are certainly easier to accommodate rather than in ceiling but i wouldnt want compromise. It’s mostly the tweeter that needs to be angled, and smaller tweeters will have wider dispersion than larger tweeters simply due to the laws of physics. Beware though, some speakers marketed with “aimable” tweeters only have maybe 10-15 degree of adjustment, which is not really enough to deal with the requirements for the front ceiling row. In essence, I don’t have much of a back wall. This is super useful, thanks! Determine speakers that meet dispersion requirements. Very educational.

References: I am setting up a new family room that is 16×20, seating facing long wall. I’ve tried front heights and rear overheads and still not diggin it. Theoretically you can benefit from adding speakers up to about 15 degrees angular separation between each one, but I think 5.1.2 is probably a good balance for you. The main rule is that you need to place and select speakers so they provide adequate high frequency coverage at the important seats. Room is 21×18 ceiling speakers will be mounted at 11 feet 4 of them. Further let’s assume that its not possible to get the optimal dispersion for both rows. Thanks for any advice. Are the polks gonna be wide enough at that height or should i look into getting Mirage OMD-5s for more dispersion (and sacrifice the timbre match)? Great write up. With 7’6″ ceilings and speakers pointed straight down we need almost ~80 degrees of consistent off axis coverage. This system provides uniform sound throughout the classroom. Great article.i have a single seatin row and 4 at,osmceiling speakers.

I think assuming decent off axis to 45 degrees off axis with those speakers (not necessarily all in ceilings, as it depends on how they are designed) is safe…beyond that you would need to measure. However there are a number of center channels that ARE properly designed and will not have off axis comb filtering…for example all the KEFs (due to the concentric tweeter / midrange), Revels from the Performa 3 series up, etc. The portion of the room that I will be using is 18’wx30’d, with a flat 9′ cieling.
