Dolby recommends all speakers being capable of 80Hz. These hardly do 100hz which is just unacceptable at this priceWhy? If you read Amir's follow-up he recommends these for on-wall usage. Check post 231-234

Most of my music is Atmos Apple Music .If you want to pure by Dolby Atmos standards, sure. You can't go wrong with these if you want high quality height speaker that match R/Reference Uni-Q speakers. I don't know about you, but my source material is maybe 20% Dolby Atmos. Regardless, I have the DTS Neural:X enabled as my upmixer.
In ceiling subwoofers do exist, and at 30hz we're reaching that territory.Most of my music is Atmos Apple Music .
I analysed a lot of tracks that I ripped off Apple Music and the atmos channels sometimes dig down to 30Hz.
I don’t think the R8 Meta are bad for what they are, I just think they’re too expensive.
That’s debatable; bass is omnidirectional so you could just use subs for everything below 80Hz.In ceiling subwoofers do exist, and at 30hz we're reaching that territory.
However, is it worth it at those frequencies? Is the perception of sound coming from above perceived different as coming from below for such low frequencies?
Thanks Amir for testing these speakers. I have 3 pairs of these, replacing Q50As. The ones I have sent to Amir will be my front heights. The others are mounted as can be found in the picture below - I am using these are height channels. From reading the graphs, it seems like a 150Hz crossover makes the most sense?
One interesting thing about the driver. Here are the specs for the R8 Meta and... The LS50 Meta: MF/LF: 130 mm (5.25 in.)
The other R Meta units (R3,R7,R11,R2,R6) all have a slightly smaller driver: MF: 125mm (5in.)
This makes me believe that the R8 Meta is using the LS50 Meta driver and not the R Meta driver; it seems to basically be a tuned closed-box version of the LS50?

Noticed you have a cathedral ceiling with exposed beams. I've always thought this type of ceiling configuration would lend itself to mounting overhead Atmos speakers that would solve the typical challenges of mounting Atmos speakers. If mounted on a gimbal, smaller bookshelf speakers could be aimed directly at the MLP and punching holes in your ceiling could be avoided. Obviously this is easier done if you select the beams/rafters and their positions with mounting those speakers in mind.
The in ceiling subs are really just a way to get them installed out of the way. Same with in wall subs.In ceiling subwoofers do exist, and at 30hz we're reaching that territory.

That was my initial idea, yeah. The limitation of the R8 in terms of frequency range, even if evident, can be mitigated by simply crossing them with subwoofers.The in ceiling subs are really just a way to get them installed out of the way. Same with in wall subs.
Sure there could be benefits in terms of room modes. That would only be the case if you also had floor level subs. Mixing up sub positioning evens out the modes.
Look up a chart of the size of a wave of sound energy as it moves below 100hrz and you can see how quickly positioning becomes a non-issue. Especially when the 1st reflection is factored in and then the ultimate pressurization of the space.
Still for evening out nulls and peaks some reccomend a meaningful variation in sub height.
150Hz for movies should be fine. But with atmos music there sometimes is a lot information below 100Hz on heights and sometimes not. It really depends on the mix.
Here are some examples of spectrums I extracted from captured 5.1.2 pop music (only left channel for each group):

The use of the heights is all over the place. It's sometimes almost similar in level as the surround information, sometimes goes down to 30Hz and other times it's barely used at all.
I wouldn't really worry about it. Everything below 100Hz is well in the omnidirectional frequency area and a sub can take care of that. The height content also is at least 10-20dB below the mains in level so having low distortion at high SPL isn't really needed either (unless you have 10 meter high ceilings).Good point and graphs. Now finding a ceiling/height speaker that realistically goes below 80Hz is a challenge for the average HT.
I need to run some more Atmos music mixes in my room!
FYI. If you are in the USA Bestbuy.com has the Non-meta for $620 new. I suspect very little ultimate difference. EAC did the non-meta Klipple review awhile ago.That was my initial idea, yeah.
