BTW, even though this thread is about ceiling mounted speakers and not upward-firing Atmos-enabled speakers, for the sake of reference here is what the Dolby patent says about the filtering used on the upward firing speakers:
Quote:
In an embodiment, the adaptive audio system utilizes upward-firing drivers to provide the height element. In general, it has been shown that incorporating signal processing to introduce perceptual height cues into the audio signal being fed to the upward-firing drivers improves the positioning and perceived quality of the virtual height signal.

For example, a parametric perceptual binaural hearing model has been developed to create a height cue filter, which when used to process audio being reproduced by an upward-firing driver, improves that perceived quality of the reproduction. In an embodiment, the height cue filter is derived from the both the physical speaker location (approximately level with the listener) and the reflected speaker location (above the listener).

For the physical speaker location, a directional filter is determined based on a model of the outer ear (or pinna). An inverse of this filter is next determined and used to remove the height cues from the physical speaker. Next, for the reflected speaker location, a second directional filter is determined, using the same model of the outer ear. This filter is applied directly, essentially reproducing the cues the ear would receive if the sound were above the listener.

In practice, these filters may be combined in a way that allows for a single filter that both (1) removes the height cue from the physical speaker location, and (2) inserts the height cue from the reflected speaker location. FIG. 1600 is a graph that illustrates the frequency response for such a combined filter.



The combined filter may be used in a fashion that allows for some adjustability with respect to the aggressiveness or amount of filtering that is applied. For example, in some cases, it may be beneficial to not fully remove the physical speaker height cue, or fully apply the reflected speaker height cue since only some of the sound from the physical speaker arrives directly to the listener (with the remainder being reflected off the ceiling).

Do you know the dispersion of these 6.5" coaxials? I guess if they are less than 90 degrees then they would need to be angled slightly towards the mlp.

Ive looked and looked and cant find the dispersion for the 6.5'' or 8'' coaxials anywhere. I know the beyma coaxials are 70* conical so I would assume the beta's are close to that if not smaller.
For box shape, i would love to see it wide and shallow with a slight angled baffle to not take up much space on ceiling. Dont get me wrong, Ill cut holes if I have to but on ceiling would just be easier. 80hz or 100hz sounds great to me, if the box is substantially smaller at 100hz, that sounds like the best option.

From my post #194 about the Volt 8:
From the usspeaker.com website,
the overall depth of the unit is 3.5 inches, so could there be a vented box, .65 ft^3 designed to minimize depth, keep the speaker very close to the ceiling and allow proper aiming OR
A sealed version requires only .2 to .3 ft3^. that's half the size box, but what is the possible overall FR?
It seems most will be using an xo of at least 80 and maybe even 100 Hz so the low end of 88 may be extended by the design(?) for smoother transition(?) IDK
And what is the DI?
I think a trapezoidal box could accommodate the depth/diameter but keep the edges shallower so angulation might be easier to obtain wrt to the mounting system.
depending on the mounting system, one designed for as close to the (8 ft.) (expected standard) as possible, the speaker would not necessarily be center mounted in the (sealed) box.
How much does "regularity"/uniformity of the box shape if sealed effect the desired overall FR. IDK.
Of course a less than standard and easily cut and assembled rectangular "box" is a tougher call/design/assembly challenge
but for some, the challenges are a good bit of what DIY is all about.
And we know you're out there . . . so speak UP!

Is that 3.5 inches with the compression driver installed?

Then add another 1.5 inches for the CD, so the minimum depth would be closer to 5 inches for the woofer and CD.

Rumor has it that Triad will have their Atmos speaker concept at CEDIA I will report back. For that matter I will try to get details on what everyone is hyping on the subject.

Nice, what angle and distance from MLP did you end up going with? And are they in line with front left and rights?

I heard from a somewhat reliable source that Triad Atmos designs are based on the ceiling bounce design. Not really thrilled.

They fire downward and are about 6 plus feet apart front to back.
They are about 8' wide apart. I can and will install another pair forward of the front pair which will become the middle pair these will then be the front ones when that becomes possible. In the mean time I need a angle cabinet for the front pair ASAP . I will also use front wides . I'll see how these that are up work out, there is no software or avr to try them with however sound great with stereo/movies. At this point I'm just experimenting until the goods are in.

I have no agenda about this, other than a better design, so consider this ( I'm retired, remember)


the volt 8" coax needs a 7.75" bolt pattern. so lets make that inside dimensions 8.25, close tolerance, so use BB
and with the CD a depth of maybe 5" so lets go with 5.5"
so internal V is about 374 . .2 ft3^ is 346 and the upper range for sealed is .3ft3^ or about 519.
I haven't plugged in the loss volumes of the speaker or the CD but there's about 160 cu. in to play with which may also allow the xo to be inside.
at a "height " of 6.5" the V goes to 442cu in. , still a relatively small package.
Does anybody know how to model this thing for the low end that will give us a solid 80/100 xo for the AVR.
Or just wait and buy something else already spec'd out . . . and save a lot of otherwise 'busy" work,
contrary to the ROI of DIY and the pleasure of good work done well.

Anyone considered 8" woofer with the DNA150 CD in 8" waveguide?

I have slanted ceilings around 15°. That means the ceiling Speakers will be angled those 15° towards the MLP. Now the rear ceiling speakers are fairly easy mounted for maximum horizontal dispersion across the MLP area it will actually give even coverage since I only have one row. The front ceiling however I considered turning 90° in reference to the rear ceiling in order to utilize good horizontal dispersion towards the MLP. I calculated the off axis to be 30-35°. Make sense? The design I am considering costs 100$ which is awesome when you need 8:-)

Ah ok thats the one. I noticed on the DIYSG forum there's a new xo design. When needing 8 og them that low price point becomes quite attractive along with a good sounding design!:-)

Bumping this thread to see if anyone has made any headway... thinking about becoming an early Atmos adopter and interested in a Volt 8 type build.

I'm considering the same thing. I'd like to see a shallow volt v-8 enclosure.

What I did was to build boxes from mdf and fit them to the ceiling cavity . Nothing fancy just functional, used the eminence 8cx coaxial,
1001 cd and 2.5khz crossover. Further since doing the in ceilings i've
also built a pair of on ceiling slanted boxes that will allow me to hear
Which pair and distance best suits the needs within my room.
So now I have six cd/coaxial speakers for atmos. Even though the denon 5200 will only do four ceiling speakers I have essentially 2fronts,2middle and 2rear. Because of my rooms ceilings layout I need to experiment and hear how best to utilize the ceiling setup.
I can do a front ht and top rear, or a number of different setups as mention in the manual. My denon 5200 will be here on Tuesday the 9th, so I'm looking forward to getting started.

^ thank you


Many of us here are avidly keen for what you may report back about your results.
In as much as they are not the "upward firing etc." your subjective/objective findings will be of much interest wrt to setting an XO aand how it does for the overhead sound.
The 5200 has the basic DSU iirc.
What would you listen to first? other than the set-up stuff, I mean?

First off, like everyone I wish that a atmos Blu-ray Disc would be here to demo.
With that said some one around here said that something regarding software
Would be coming down the pike maybe today,don't hold me to it,I heard it from some other party on this forum.
I was able to run a demo with the DIY speakers in the ceiling & on by connecting them to my denon 4311ci just to here and get an idea of how they sound up on the ceiling. What I did was connect the top rear to my back surround input,the middle
Pair to the side surround input and the front top pair to the height input of the 4311.
I ran audyssey and sat back with my buddy and listened, the results were amazing,
The diy's came thru nicely,they pretty much timbre matched and were set to 80hz by Audyssey . They are close enough to the L&R sight line, I think there is some
le-way here for placement not a lot but some. I think it was Roger Dressler who said the same thing. So Asarose247 you should be good to go how you set up that cool rail/rack on your ceiling which you mounted the speakers to. More people here should consider that setup of yours it would fit for many who have a similar layout.
When the 5200 is setup I will run some movies with heavy surround , like transformer dark side of the moon etc. Hope the upmixer setting does it justice.

On a 12ft ceiling, do the height speakers have to be aimed? or can they point straight down? I don't know about hanging Volt V-10 boxes on ceiling (wife would freak!), but maybe white grills with volts hidden behind? Just lay the volt boxes face down with driver shooting through the 10" hole and speaker grill? or would the thickness of the drywall mess things up?

Erich, glad to hear this is a possibility!! I know you're re-structuring and focusing on bigger projects, but these lower-cost speakers are helpful to us with smaller budgets getting started

Toed my pair in to cross in front of the MLP and it's so smooth/seamless without a center, seeing now why some prefer going phantom

Still anticipating the results of the higher cost coax's and towers for the future, too

Keep up the hard work

That flys in the face of Dolby's own white paper that says 90 degrees plus!

Perhaps he meant one direction ? Lol. Like left only.

He was really clear on it, and the first rep brought him over to answer my question on dispersion pattern.

It sounded odd to me too.

For what it's worth they used triad brand in ceiling themselves.

The procella demo sounded better to me, those were the normal not Atmos specific models which have 80 degree pattern but on the ceiling in Atmos locations.
