Could recommend speakers suitable for extra-large spaces?

THX recently joined AOM https://aomedia.org/press releases/THX-Joins-the-Alliance-for-Open-Media/
Good for Eclipsa Audio. Maybe more competing hardware to Dolby in the future.

THX has joined several AOMedia working groups, including the group focused on IAMF (Immersive Audio Model and Formats), a new open-source immersive audio technology. THX brings to the working group more than four decades of cinematic experience developing high-fidelity certifications, technologies, and standards for the proliferation of excellent entertainment experiences everywhere.

I have a very large plot of land in the countryside. I hope to build a private cinema from scratch, with a screen size of over 350 inches. The cinema is approximately 14 meters long and has a volume of around 700 cubic meters. I want to set up a surround sound system, and I have the following requirements for the cinema's audio:

1. The room will undergo professional acoustic design. The budget for audio equipment is not a concern, and we should strive to achieve the best possible results.
2. A very wide sound field.
3. Neutral, accurate, uncolored sound with large dynamics and high resolution.
4. The best surround sound effect.
5. A very high sound pressure level. I will be sitting about 7.5 meters away to watch movies, so the speakers should be able to reach reference - level volume at a distance of at least 7.5 meters while maintaining excellent sound quality.
6. The best bass effect, reaching infrasound frequencies.
7. Approximately 20 seats.8. Give priority to the sound quality at my seating position.

Are there any speakers recommended that meet these conditions?

oh the days of decades ago projecting at CIC/UCI in real 35mm with experimental overhead surround , decades before atmos , the listening experience i have

Last night a close friend of mine bragged to me about his purchase of two massive but-shakers for the couch ( and swore me to keep it a secret from his wife).
I immediately thought of this thread. Do the OP plans such а crazy things ?

Is the purchase of such equipment for the purpose of obtaining a 4D experience?

How can waveforming go behind practically no room modes and something that works much higher in frequency? It can't of course.
Waveforming or what's in reality an advanced version of DBA is limited to a smaller frequency area, takes up necessary space for other treatment (i.e. diffusion on the rear wall) and cost a lot more.

SBA would be better approach of one wanted to have an array of woofers on the front wall because it will unlike "waveforming" work for all bass frequencies and can be combined with the needed treatment on the rear wall. Waveforming/DBA is more a WAF approach in a living room if treatment can't be used. It has drawbacks as mentioned.

The CBT design doesn't function like a traditonal line source and is actually a strong point souurce without the diffraction issues of a coxial and much lower distortion. A benefit with CBT in a surround setup is also that one need a lot less speakers due to the wide broadband coverage, which minimizes lobing and comb filtering greatly. The more channels you have, the more lobing and acoustical issues there are. Something generally not told by those who want to sell a large amounts of speakers.

The effectiveness of Trinnov's WaveForming technology has been well verified. Are there any actual cases of the SBA you proposed? If CBT is so good, why do almost no manufacturers adopt this design? What are its disadvantages? I don't mean to question you. I'm just confused.

I have barked around here a lot about 2 speakers (plus a sub or two) being the best for me, but with a very large room for best results you undoubtedly need multiple speakers with room calibration. Basic physics.

14 speakers overhead , challenge accepted when i have the time for extra , CIC/UCI , sonic whole atmos overhead sound

x9 so all i need to out dolby's overhead spec in the dust , is x6 , 15 overheads only it be not like anyone else has , stereo once you know how that works the cat is out of the bag
View attachment 430015

actually i could expand it to 35 JBL easily but overhead surrounds have been around since 1969 and late 1980's so what that has already been done , below surround is the last surround frontier which i have been using now for just over 10 years and idea came to mind 1998

stormaudio isp 32 atmos plus - rack amps in kitchen with few simple easy improvements with real pinpoint overhead surrounds and system can do several overhead sound formats , the B-chain in my system is always progressing expanding

spending thousands on speaker is plain daft , less is more , yes less cost = more and real world sound is , free of change doesn't cost a penny in nature itself , for which nature itself cannot be fooled
speakers drivers side by side coupled with new a breed as sound moves in tiny degrees , i can hear sound shifting with earplug in one ear and sound can shift , so i have a new idea in plan , but room is too small and no way am i downgrading these rare real world , JBL professional motion picture surround speakers back down to smaller on the ceiling control 5 again , nothing wrong with them , just the 8330 THX series been used in real world THX cinemas , not some unknown speakers home theatre that haven't and cost daft amounts of money per single speaker , anyway i can plaster the ceiling if i wanted to with x35 JBL 8330 A THX if i wanted to

doing other installs with some of below surround arrays below back row seating and other row of below surround behind it and below front row and few rows outwards in the room

Why install floor channels? Are floor channels taken into account during film mixing? Which cinemas are equipped with floor channels?

i asked for pictures of your home , few of us ASR members have shared now its your turn so we can least get an idea of all of this ?

 

[haerinnn]

Not yet. Since it's still in the planning phase, I haven't engaged a professional company for the design. The final area might be smaller or larger than I expected. I aim to achieve the best possible results. This private cinema will be built from the ground up. Before proceeding, I want to learn as much as I can about this.

Hi

Most of of us can only make suggestions based on speakers we think or believe, meet the design criteria. I am not sure many of us have the required experience for what the OP seems to desire: An Extreme High End Private Cinema system.

There are people here that can tackle such a undertaking: @amirm with his Madronna Digital and @CINERAMAX come to mind, there may be others

This is well above my paygrade..
Bowing out..


Peace.

What do you want to see? I'm not at that place right now. I plan to move to the countryside after I retire. This is the only photo of that piece of land I can find on my phone. I took a picture of the corn because there wasn't much else to photograph. In the countryside, everything in sight belongs to me. I don't think this photo can provide any useful information.

yep what i expected a troll with home theatre field of dreams very funny

couldn't care less

You posted so many comments on this thread and asked me for photos. In the end, you said "couldn't care less"? I think you're the biggest troll here.

Apparently he failed to read your first post and then jumped off on you. Apologies. He won’t be interrupting again.

I think providing a basic room drawing is reasonable when asking for recommendations on an "end system" though. I answered to the concept of a "big room" but shall ignore the thread henceforth.

If the room is undergoing professional design I assume with some certainty those professionals may have good suggestions. You may run those through the forum for some experts to opine. I am not one of them for cinematic rooms.

He said right up front that he hasn’t built it yet and gave basic dimensions. I don’t see the problem. Based on his speaker selections the room size may scale. My opinion is it’s smart to pick the speakers first and build the room to accommodate them.

I understand that any doubts are justified. I've already described my situation at the beginning of the post. If anyone doesn't believe it, they can just scroll past this post instead of making senseless personal attacks.
