Thanks for the explanation, that was something I’ve been struggling with. I had the conduits there as I was originally going to get book shelves but they suddenly weren’t available in the colour i chose so had to go with the SR900’s

 

Now to get some more speaker wire and work out moving the SR900’s.

 

I’m thinking maybe it would be worthwhile eventually getting additional seats in front of the step and hopefully should make it all better.

 

Once i get the new PJ and AVR I’ll get the local shop (West Coast Hifi) to tune it all in and hopefully should improve things no end.

I'd recommend 7.1.2 - your room is deep enough for it. Depending on screen size, consider moving your seating forward a little (about 0.5m).

Everything is a compromise in a non-dedicated room. Even dedicated rooms can't have everything.   I have a 5.2.2 and it sounds great to my ears. I would love to have 4 atmos speakers but as

I'd go the other way. 5.1 to 7.1 is not that big an improvement from a listening perspective. Having 3D overhead is a big improvement. 

Yeah cool, I think you need to sort out the seating before the speaker position. And think about the primary seating position, being in either the front or rear row, as this will change the location of the side surrounds. 
I reckon if you put a row in front, you will sitting in those most of the time, and if that’s the case, layout the speakers for that row, with the side surrounds at 90 degrees to the front row, of just behind. 
Also need to be thinking about the height of the head rests in relation to the speaker height, make sure that you can seat every speak from each seat, so don’t mount them too low. Also you will need to see all of the screen from the rear seats, so don’t about the height of the front row seats. 
With that front row I place, having rear surrounds on the back wall makes a lot of sense, as does .4 for atmos.

So much conflicting information out there!

Don't use bipoles - that is old way of thinking.

Unless you use them as surrounds (not rear surrounds) BETWEEN 2 rows of seating so that each driver of the bipole is facing at each row of seating.

Yeah for sure, 100% on conflicting info.

 

 I try to stick with the manufacture recommendations on this kinda thing. If you look at the Aria 900 user manual, linked below, page 28 it states;

”Do not place surround speakers too far behind the listening point, as this will lead to degraded sound perception from them. Aim for placement along the side walls for more enveloping sound effects”

 

https://www.focal.com/sites/www.focal.fr/files/shared/catalog/document/notice_aria900.pdf 


the Dolby Atmos Home Theatre Install Guide has them left and right of the listening position.

 

https://www.dolby.com/siteassets/technologies/dolby-atmos/atmos-installation-guidelines-121318_r3.1.pdf


And that with what I experienced with my system, listening to 5.1 audio with my SR900 in a similar position to yours, and then using a in wall at 90 degrees to my head, there is no way I am going back. 
 

If you do go 7.1 for the ear level speakers, you will need something on the side wall anyway.

Yeah spot on the SR900 that he has would be ideal for 2 rows of seats being used as side surrounds.

So... sell the SR900's for some nice Focal In-walls looks to be the way to go then?

 

Thinking 2 x Focal 300IW6 for the SL and SR then 4 x 300ICW6 for the in ceiling speakers?

You can always test placement of the left and right surrounds with what you have and compare it to them being on the rear wall. Try moving the SR900 to the left and right of the seat position, recalibrate the receiver and have a listen. You could sit the speakers on top of something (a box) to get them to approximate ear level and try it. Listen to something that has a good surround track and compare before and after. That will tell you if you are on the right track. If you think that its better move them there, if not leave them as is.

 

I wouldn't be replacing the SR900 at this stage, as they are a fantastic surround speaker, and especially if you are going to be putting in two rows of seating, as @niterida mentioned.

Yeah thats actually a good idea, I’ll just go buy some more speaker wire as I’ve ran out. I think having them at ear level will be an improvement nonetheless. 

 

Currently they are firing out above ear level by 500mm.

When i went to buy the speaker wire today from the shop I was told that the Denon amps may have issue playing streaming services on HEOS whilst playing anything in the main zone. With your X6700 do you find an issue with this at all?

 

The extra power and 13 channels is one of the reasons I’m upgrading so if you cant do this may just get the X3700H

I don’t use HEOS, but I know the older versions couldn’t do TV audio to anything but the main zone. Where the 6700 does that. I can check it out later and see if it lets me. Will report back.

Thanks I’m really interested to know if you play content in the main zone if it stops Spotify (for example) being played in zone 2/3. I’d be surprised if thats the case tbh as it would make the whole feature pretty pointless.

Ok, so I have tested and it works as expected. 
 

i reconfigured my speakers, so that 7.1.2 was assigned to main zone, and 2 speakers for zone 2, by reassign the top rear speakers to zone 2. 
 

I can play a atmos sound track from my shield in the main zone, and play music via HEOS in zone 2 at the same time. The movie came from the 7 ear level speakers, the sub and the top front speakers, and music came out of the top rear speakers. Which is what I expected.  
 

Keep in mind that if you are doing 7.1.4 in the main zone. You will need an external amp to run zone 2. But if you are doing 5.1.4 or 7.1.2 the 6700 won’t need an external amp for zone 2. 
 

Hope that helps/

That’s great, thanks for that. 

 

I’ll be doing 5.1.4 and just 5.1 in the immediate future once i get the new PJ and amp. I then need to get the atmos speakers.

 

I was told at my local store they (local rep) are trying to get rid of all their Focal products as they may be leaving the market in Australia also?

 

Not sure if there is anything I’ve read online to that accord. 

 

If there is any truth in that might be best to import the Focals from UK and save on GST. I was recommended Krix in ceiling speakers but would rather stick with Focal tbh

Please consider 7.1 as well. As I stated before, I would rather have 7.1.2 over 5.1.4. But with that 6700 you can run 7.1.4 and then your zone2 from a small amp.

 

I reckon your local rep is full of it. Focal have been in Australia for years, both in home and car audio markets, and they appointed a new distributor last year (maybe year before). There is no way they would be pulling out of ANZ. Normally when you here things like that is due to the local shop having other factors at play, this reseller market has a lot of political forces at play.

That would make sense but i'll see what I can get close to when i am ready to get the speakers. I've been recommended Krix speakers so many times there so would expect some sort of relationship with them.

 

I've never heard of Krix before so no idea if they are any good.

 

Also another factor in being an issue for 7.1.2 is that I have a sliding door which runs past where my Surround L speaker would go and that wall also is not cavity. It really impedes my options.

 

I'll be moving the SR900's to 90 degrees of listening position today and testing.

 

I did notice when I went to my local shop yesterday they had another brand of speaker mounted like I have my rear surrounds in a 5.1 configuration and when i spoke to them it was suggested what i had set was correct.

So Krix is a well known Adelaide based brand, yes they are pretty good, however I believe that they import their drives from China and make the cabinets locally. 
Considering that you already have Focal Aria in the system, why wouldn’t you stay with the same brand, with the same driver and tweeter technology across the board. And these are all made in France buy a company that makes the entire product, not just parts of it. Also Moving to another brand will change the sound signature between front and rear, and this doesn’t make sense to do. 
 

about the left surround, yeah makes sense about the door, your layout didn’t really show that. Makes sense to try a few locations anyway.

I'd pretty much discounted Krix from the moment i was quoted them, rather keep all the same speakers.

 

I've moved my SR900's so they are now at 90 degrees of listening area and at ear level. I've then measured (with a tape measure) distance to all speakers, set that in the AVR3312 and used an SPL meter (iphone app variety) to set each speaker channel level to 75dB as listening postition.

 

Sure this isnt the most accurate but I think its atleast done the measurements more accurately than Audyssey.

 

After doing all of this my system sounds a lot better. I think i should have enough wire to move the speakers back to the rear position and see how the system sounds but suffice to say big improvement so far.

 

I'm going to test it out with a full movie tonight once the kids are in bed.

 

On another note, do you set your SR900 crossover at 80Hz or 90Hz? I've got them set to 90Hz currently.

Nice!. 
 

Just remember with audyssey that it will make allowances for frequency response changes due to the room.

 

The SR900 is 85Hz to 28kHz, and low point is 67Hz, so I would be setting at 80Hz, but 90 is cool too.  
 

Let us know how you go.

I already ran the Audyssey setup a few months back so left all those settings, and i just modified the distances and the channel levels today.

 

Did a bit more googling and most of what I’ve found suggested bipoles should go on back wall in a 5.1 setup (and not not at 90 degrees) at approximately  600mm above ear level.

 

I’ll move them back tomorrow and see how it compares.

 

Also need to move my PJ screen tomorrow as I’ve decided its too low.  Good job I’m covering school holidays!

Moved the SR900's to the rear wall and the result is even better. I am wondering if i would be best to lower them somewhat maybe 300mm down from where they are now so they are 300mm above listning position.

 

Also moved my PJ screen higher and reset all the lens memory. Everything looking and sounding a lot better now.

 

It does raise the question though is the .4 too much for my room for Atmos? I'm wondering if i should just get the 2 x 300ICW6's and see how they go? There is nowhere to demo.

How did you go with the SR900 location? Try some more places?

 

On the .4, I don’t think it’s too much for your room.  My room is slightly bigger and it works great.
 

With your lounge on the rear wall, directly above could be considered top middle or top rear, and there is a large gap of no speakers between the front sound stage and your rear speakers on the rear wall. So .4 makes more sense for you?


Having said that, and as I said before I would rather have 7.1.2 over 5.1.4 any day.

I dont have many other places to put them. I do think they need to be lower by 300mm or so I think so they match the fronts.

 

Then in conjuction with the Atmos I think it will sound great. After modifying all the distances manually and setting volume levels manually to 75dB it certainly packed more of a punch than it ever has. I think my PB-1000 sub is happier.

 

My wife keeps saying it's too lound but I think i can dial that out ?

Yeah WAF is important.

 

Mine made a comment the other day about how much clearer that the monsters are behind here her when she is gaming with the new speakers installed. I think it freaks her out a bit. That a win right?

So here is my plan, started to do something fancy in Sketchup then couldn't be bothered as it was taking too much time.

 

I do have conduit run in the walls either side of the couch however if i moved the SR900's there would that improve things and also would i put them at listening height or a bit higher. So far they are about 500mm higher on the back wall.

 

Im also upgrading to the Epson 4k TW9400 projector to replace my Panasonic 8000. I've also got a 130" cinemascope screen.

With a room of this size/layout, you really should move the couch forward before thinking of 7.1 or atmos - you can always build a plinth for it to extend the step if you have to

Hi.

I have a 4.7x3.6m room with 3.3m high ceiling. All carpeted everywhere but the ceiling.
(some old photos: https://www.avenard.org/home%20cinema/Pages/1.html https://www.avenard.org/home%20cinema/Pages/2.html before I got the SP32)

 

It's been configured as a 7.1 setup for over a decade now, Dynaudio Contour series for the front, center and left/right surround, audience 40 at the rear.

 

In this room there's a 3-seater couch at the rear, and you sit at 3.7m from the screen. Speakers are located in what THX used to recommend at the time. So left and right surround are about .6m above ear level, and about 30cm ahead of the sitting position.

Rear surround is mounted on a tall bookshelf, similar height to the left and right surround and about .8m behind where you sit.


Due to the configuration of the room, I can't relocate the side surround speakers and place them lower (there's either a door in the way on the left or a fire mantel and window on the right)

 

I recently got an Anthem MRX 1140 AVR to upgrade my existing Primare SP32. It can do 15.2, with 11 channels integrated amplifier.


I got a pair of focal 300ICW6 ceiling speaker following the advice of the store where I got the 1140 who said that ceiling speaker should be slightly ahead of your sitting position.

He said that as I was sitting towards the back, and there was only a single row of seats, there was no point having 4 ceiling speakers.

 

Now I'm kind of getting confused because apparently Dolby suggests 5.1.4 over 7.1.2 ; yet THX suggests the reverse.
Now I've found no proof that Dolby actually suggests 5.1.4 over 7.1.2 other than people in forums saying that Dolby said so, and I've extensively browse Dolby site and documents:
https://www.dolby.com/about/support/guide/speaker-setup-guides/


So sounds more and more like hearsay and people simply repeating what they were once told.

 

Doing holes in our ceiling is already a contentious matter with my wife, who doesn't want her freshly redone and repainted ceiling get damaged in anyway.


Secondly, I hesitated with the 300ICW4 and that's what I first got but because they are so tiny I exchanged them for ICW6; was told it would make no difference to the sound quality as atmos ceiling wasn't going below 150Hz per spec, but old convictions that size matter are hard to kill.

 

What would your suggestions for a proper setup be?
thanks.

the rule of thirds is usually pretty effective at placing yourself audio wise... so not in middle of the room... where there is usually a null... and not sitting up the back which is usually where bass gain resides and you are close to he back all that can be detrimental to coherency of vocals as well.. with rule of 1/3rds you end up sitting at 2/3rd room depth which also mean you dont need a big huge screen and it leaves plenty of room for 7.1 and 7.1.4 if wanting to go that way... sitting at 2/3rd room depth also means you dont usually need a HUGE screen using THX spec for immersion at 40 deg viewing angle.

 

yes the heights placed slightly front of main listening position works... as does placing rear heights slightly behind and where following rule of thirds there is plenty of room to place those rear heights so not all on top of each other wiht the side and rear speakers....

 

in essence if you can setup for 7.1 with well positioned main listening position you should be able to easily 7.1.4

dolby doesnt suggest 5.1.4 over7.1.2 or anything like that. what they suggest is speaker locations ... it comes down to what you can accomodate...they have suggestion for 5;1, 7.1, 5.1.2, 7.1.2, 5.1.4 and 7,1.4... 

 

what you find is a LOT of folk and i kid you not its amazing how many folk want to jam main viewing position hard up against back wall and get the biggest screen they can get in... which of course leaves no room for 7.1 let alone even doing 5.1 even justice and also forcing them to get a huge screen to compensate for extended viewing distance... and also a compromised 5.1 setup that is not ideal and will squeeze 2 more speakers in front with clearly no room for anything else...

So right now it's at 4/5th. If I move the couch to be aligned with the side surround, it will be almost exactly 2/3rd back (3.13m ideal vs 3.05m actual)

I use a projector, so my screen is 2.4m wide, I don't need any bigger :)

 

Actually, now that I think about it, it's probably where I originally got my couch positioned when I first installed it.

 

I guess the fundamental question is if 4 ceiling speakers is a much better setup than 2. Looking at dolby's recommendation, you can't upgrade from .2 to .4 without drilling new ceiling holes. Can go from .2 to .6 though..

 

Dolby diagram don't make it ideal to identify where to put speakers ; like https://www.dolby.com/about/support/guide/speaker-setup-guides/7.1.6-overhead-speaker-setup-guide/

 

like how far from the back wall are the heights supposed to be? they seem to be even behind the rear surround ; which I couldn't achieve in my setup.

I wouldn't be going .6 dolby locations though and instead going 7.1.6 with Ch and Ts speakers are far more useful but your anthem does not as yet support DTS-X pro or auro 3D for that matter so would be a waste... so suggest with your anthem to stick with 7.1.4 at the most

if you want a rule of thumb... in every decent setup i have listened to... if seated you couldn't see the front heights... but if moved your eye brows back you'd see them...there is some flexibility if look at the drawing with the vertical angles... reality is you will be missing ceiling rafters to place anyways ...so will end up there abouts...  dont stress about it ... most in ceiling speakers have aimable tweeters and can just aim them at you. with the rear heights just place them behind the couch somewhere in between other speakers so things arent on top of each other... again dont get all @nal  about the locations.... :)

 

as far as locating the in ceilings along the room try to have them in line with mains or just inside the line of them where located again roughly as per the drawing below... but again dont get to caught up in trying to get it exact !

I thought the MRX 1140 did DTS-X Pro ; it's in the spec at least.

My ceiling is 3.3m high, my head would be 1.8m away from the rear wall if sitting 2/3rd of the way back.

There's no way I could achieve those angles, trigonometry rules.

 

To achieve an angle between the couch and the ceiling that would be between 30 and 55 degres, you would have to have the height speaker between 6.6m and 2.3m in front or behind the couch.

 

Achievable at the front, certainly not the back where there's only 1.6m (1/3rd of 4.7m).

To fit in Dolby recommendation and have the height speaker say 1.2m behind me and .4m from the wall), the ceiling would need to be 1.7m high.

Has Dolby even considered the impracticality of those guidelines in a normal house?

 

Even with the very low Australian minimal height ceiling of 2.4m you would need the room to be absolutely massive to get anywhere near those guidelines.

 

The other thing annoying is that before Atmos, all recommendations were for the surround speakers to be 3 feet above hear level. Which is exactly where I set my speakers. Now they are recommended to be preferably at hear level or 1.2x the height of the front speaker. The configuration of my room doesn't allow for this unfortunately.

 

I guess I should have considered those impracticalities before getting that AVR and the rabbit hold of this Atmos thing.

My ceiling is 3.3m high, my head would be 1.8m away from the rear wall if sitting 2/3rd of the way back.

There's no way I could achieve those angles, trigonometry rules.

 

To achieve an angle between the couch and the ceiling that would be between 30 and 55 degres, you would have to have the height speaker between 6.6m and 2.3m in front or behind the couch.

 

Achievable at the front, certainly not the back where there's only 1.6m (1/3rd of 4.7m).

To fit in Dolby recommendation and have the height speaker say 1.2m behind me and .4m from the wall), the ceiling would need to be 1.7m high.

Has Dolby even considered the impracticality of those guidelines in a normal house?

 

Even with the very low Australian minimal height ceiling of 2.4m you would need the room to be absolutely massive to get anywhere near those guidelines.

 

The other thing annoying is that before Atmos, all recommendations were for the surround speakers to be 3 feet above hear level. Which is exactly where I set my speakers. Now they are recommended to be preferably at hear level or 1.2x the height of the front speaker. The configuration of my room doesn't allow for this unfortunately.

 

I guess I should have considered those impracticalities before getting that AVR and the rabbit hold of this Atmos thing.

 

Mate

its just a guide, go for 7.2.4 - you won’t regret it

my signature has a link to my current setup in case you want to see how it looks

Nice setup, love those confidence C1.

 

Which ceiling speakers did you use? Are they the white round on your ceiling? what size are they?

What are the dimensions of your room? So you have them in the four corners of the room pretty much. That's easier design to set up!

they havent figured out how to get it working as yet. they have dual sub EQ also in the spec sheet and havent figured that out as yet either... so very much a work in progress...

1.2m back and 0.4 from back wall... for rear heights seems too far back to me and little too close to wall when doest need to be ..I would aim to have them somewhere thereabouts between you and the rear speakers/back wall...

thats why i said earlier dont get too stressed out... it is only guidelines... and believe me when i say i have listened to a lot of systems before doing mine about 5 years ago also heard a lot since... dont get to wound up and as long as slightly ahead of you and slightly behind ...even just one step it works fine... keeping in mind each speakers dispersion is different...have amiable tweeters...

that ceiling is quite high.. most folks have 2.4 to 2.7m ceilings... so you actually have quite an advantage over most even just here...

 

1.8m is more than sufficient to fit in not only rear speakers but also rear heights without everything all on top of things. my wall is exactly the same and i have my rear height speakers just behind the couch and works an absolute treat :) 

 

you are likely to be constrained with what you have behind the ceiling plaster anywise ... so keep that in mind... start checking with the stud finder where all the beams are ... that iw what is likely to limit where can have them anyways ...

yes that was "before atmos" actually lets call it 3D audio shall... as atmos is quite restrictive... formats like DTS-X are not so specific i can tell you of locations and atmos is still only providing guidelines... dont over think this... 

 

with your speakers again i can say what is important is some height differential... you have quite high ceilings... id leave your surrounds where they are ... as there will be still quite a height differential between your wall mounted surrounds and your height speakers to make them heights .....

think beyond atmos... think 3D audio thats more encompassing....in day to day likely find atmos coming into play rarely... its more dolby surrounds and neural-X and i can tell you neural -X is superb for great bulk of DTS-HDMA sound track blu-rays likely have. superb for great slab of netflix and streaming, even FTA TV thats 2 to 5.1 pcm and neural - x does a superb job with all that ... go for this go for 7.2.4 and enjoy... there will be a LOT to enjoy... i have been last 5 years ... never looked back ...

that's annoying ! Wonder if I made the right choice with this AVR. It does sound really. In fact I can't tell the difference between just this AVR and my previous system that used separate amp (Primare SP32, Primare 30.5 amp and rotel stereo).

I liked what @petetherock showed, with his setup,  4 height speakers aligned with his front ones and in each corner of the ceiling.

I like this setup because it's symmetrical and would give me a higher WAF score and will definitely looks nicer than height speakers simple placed toward the back just ahead and behind the couch.

 

So I may end up just doing that. Apparently the amp calibration should deal with this setup just fine and is covered by Dolby spec.

 

Good to know about height being okay. would be annoying to change. Was considering disabling the side surrounds and running 5.1.4 instead ; I will see on what sounds better.

theer is no logic in that. the height speakers build upon your bed of surrounds you have now... please dont be switching off your side surrounds ... they play a pretty important part in sound field :)

aesthetics is aesthetics go with what feel comfortable with. in my setup it is just in ceilings and you dont really notice unless looking up to pick them out. its all still pretty symmetric  as expect to be.

AVRs have their limitations... just cant squish 11 channels of amps of quality into chasis without serious compromise in amps or pre stage. if wanting to do a proper calibration would want to trial with and without amps in tow also be aware anthem calibrate louder os can initially give impression of wow sounds better but its just louder.

would you have a photo of your ceiling handy ? :)

sure. But I would have got the AVM70 if I wanted to be bothered playing with amps again :)

wow Al!!...how many ceiling speakers do you have?

I see  4 for Atmos + 1 for Auro-3D VOG, and there looks like another up front of the screen in the centre as well?

Apologies if you have explained this earlier in the thread
