Upgrade to atmos 7.1.2 vs 7.1.4 vs stay at 7.1

gurot1gurot1 Posts: 488
This audio upgrade bug is killing me. Debating whether to make the jump to Atmos. Main issue is that there is duct work in the ceiling that hangs down a foot from the ceiling. It is about 40" in front of my MLP (which is 36" from the rear wall) My ears are approximately 46" from ceiling. I am currently running LSiM 705 fronts, 706c centre and LSiFx for side and rears. Debating whether 4 atmos speakers are doable in this tight ceiling space or if I should just install 2 in-celing atmos speakers at the front edge of the couch. I could potentially install the rear in ceilings about 2 feet behind MLP and 1 foot from rear wall and the other heights would be about 30 inches In front of MLP.

Excuse the mess, I am looking at making some panels on the rear wall behind the listening position. Interestingly, when I was doing some REW sweeps, once the safe n sound was deeper than 6" I started getting a null at about 148 Hz which got narrower and deeper as the panel got deeper. The bass traps are already up in the rear corners. I had removed one of the black speaker cloth covers in front of one of the bass traps. I am looking at whether the speaker cloth will look ok on the ceiling close to the projector screen to darken it for watching movies on the projector vs putting some blackout curtains on the ceiling during movies.

Looks like I will have to go with either Polk 700 LS or 900 LS in ceiling speakers to match the rest of the setup. Also, will probably lower all 4 surrounds 6" to 1 foot due to atmos wanting lower surrounds, but would rather leave them where they are.. When I finally get around to deciding on what to do (if I even end up upgrading to atmos (will need a new receiver too!)), I hope it is a noticeable improvement on non 4K movies.

Thanks for help as always.

    Not sure how well atmos speakers would perform overhead in a drop ceiling. My gut says Atmos would be overkill in that space.

    What, are you suggesting that I not waste my money and time on this venture? Is that even allowed on this site? :p

    Thinking you could upgrade some other aspects. We will never tell you not to spend money. :p


    If you don't have 4K, its my understanding you wont have Atmos capability anyway, so why not upgrade what you have to get there first, then think about speakers for that ceiling.

    Those ceiling tiles aren’t design to support the weight of a speaker, so you would have to have a plan for that.

    The speakers would have to be placed a couple of feet in front/behind the duct run, assume that is what the painted area is. The relation to your seating position will determine if it’s feasable. Probably looking at 2 speakers for overhead duty. Don’t think 4 would add any benefit, that is if that duct run is toward the center of the room.

    You are correct in that the duct work is the yellow painted area. I have 40 inches in front of MLP to the duct work and 36" to the back wall. Room is about 19 feet deep and 11.5 feet wide. I thought Atmos was encoded on some of the regular blurays as well, but I think as more 4k content comes out, they are going to push that format and include atmos mix on those discs and not on blu ray from what I hear. This site has been a money pit for me. LOL started with some rti10s and a csi3 centre and some r15 for surround and a velodyne sub..and have progressed to the current setup. Now if only the kids would go to sleep on time so the wife and I could enjoy some non-cartoon flicks...well, at least we all watch the marvel movies. Of topic, but the SVS aseq1 definitely helped tighten up the bass on my dual subs.
    No worries about jigging something up to support the speakers, I can do that, ideally don't want to cut into the beam of the drop down ceiling to place speakers, but will cross that hurdle once I get there.

    It's funny you mentioned the svs speakers. I was looking at those as well but then was thiinking it probably better to stay in polk lineup. But I could mount the svs under the soffit as well for optimal spacing.

    I do think it is best to stay with the same line to manufacture. Your case Polk doesn't make a speaker to fit your needs. Ceiling Tiles can take a ceiling speaker install but I don't know how it would sound. Our lobby at work has them for soft background music. Don't think they could take volume.

    First off what is MLP?
    What height is to the tweeters of your current surround system?
    What Sub do you have?
    Anyway Atmos is the BOMB BUT careful placement and as correct as possible is ideal for the overall best results.
    7.1 is cool but not with Bi polar speakers. You should be using all Mono Pole style speakers for the best overall effect. Bi Polar speakers where actually designed for Dolby Pro Logic not Dolby Digital and beyond. You can however get away with Bi polar design for side surrounds just fine but not surround back.
    If your tiles are hard they will hold a in ceiling speaker all day. If they are the soft design then you would have to place a thin sheet of plywood behind the tile to support the weight of the in ceiling speakers.
    In that room I think 2 would work just fine. I don't see a need for 4 but 4 does sound incredible when properly placed.
    4k is the way to go and if your looking to upgrade, 4k is also incredible.

    My personal quest is to save to world of bad audio, one thread at a time.

    Great idea of using the plywood @mantis actually if the supports can take it replace the tile with 1/2" MDF. If going plywood Lowe's sells a project panel (4x8) sheet that is very good and strong. I've used it for drawer bottoms https://www.lowes.com/pd/RevolutionPly-5mm-Poplar-Plywood-Application-as-4-X-8/50121135 thin and light weight and somewhat strong, or go with 6mm baltic birch.

    ATMOS and DTS-X are great. My room is not the ideal lay out for the format but it sounds way better with it all than without. I did do a day of experimenting when I put in the T15 for surrounds. from 5.1 to my 5.1.4 sounding the best. On non ATMOS and DTS-X movies the AVR will upscale to use the ceiling speakers. sounds way better than 5.1.

    I have been debating whether to just remove the back speakers and use a 5.1 setup instead. I remember reading that monopole is the best for the rears, but was getting a decent price on the LSiFx here. They have a pretty crisp sound to them. I would need some speakers that aren't too deep for the surround backs. I don't really want to do in wall rear speakers either. In all honesty, I have been thinking if a 5.1.4 might be a better setup than a 7.1.2 for my room. I have no problem jigging up something to keep the in ceilings in place. The tiles are soft, so was expecting to have to make something to keep them up there. Do in-ceilings need a hard surface towards the front for proper sound production? Not sure how much of a box they need around them for optimal sound. I am not the best carpenter, but can get the job done, especially since the work won't really be visible.

    MLP(main listening position...aka where I sit and enjoy a beverage while watching a movie). You can't really see it in the photo as it has a bunch of cushions on it in the pic so you don't see the sofa.

    As far as subwoofers are concerned, there are a couple of 150 pound SVS beasts lurking behind the sofa...taking up much of the room behind there are a pair of PB13 Ultra's...no plans to upgrade those beasts anytime soon. Putting them back there really helped clean up the room at the front which was getting super cluttered when the subs were there. Once I ran the AS EQ1 calibration, you can't really notice that they are right behind you. Using a Pioneer SC 1227k for the AVR. A B&K 5 channel power amp powers the front 3 and the side surrounds. Also using an Emotiva xsp-1 preamp hooked to the subs and the power amps and avr to emotive in home theatre bypass. The preamp is for 2 channel music (which I rarely get to sit and listen to these days). If I go atmos, thinking of a midrange Marantz AVR potentially to replace the preamp, avr and aseq1. But finding an AVR will be a separate journey!
    Thanks for all the discussion/suggestions so far.
    Oh yeah, the rear tweeters are currently at....let me go measure...70 inches from the floor and about 19 inches to ceiling.

    If you haven't already done so, look around at the Blu-ray content in Dolby ATMOS. If you are prepared to acquire it then decide if you are ready to upgrade to 4K, UHD, HDR, etc. now or at some point in time.

    For now, you can always try some from height channels using Dolby Pro Logic IIz, DTS Neo:X with your Pioneer AVR. It will give you a taste of height channels and maybe calm the upgrade bug until you figure out how best implement ATMOS / 4K to your system.

    That's food for thought. I shall investigate those settings on my current AVR, it's something I hadn't thought of. hmmm...maybe I should look for a good deal on some LSi7's for my rears! I spend more time thinking about the HT setup than actually using it! Currently making some panels for the rear wall that will double up as a bit of shelving on the back wall. Almost finished that, then gonna make one 6 inch panel that can go behind the centre channel during movies...Hmmm, I could store it on the new shelf in the back lol. Then gonna use some black speaker cloth to darken up the ceiling in front of the projector screen that can be rolled out during movies and then back up again when not in use (yay, multipurpose rooms!). Don't want to paint the current tiles and the speaker cloth allows the vent duct in ceiling to breathe.
