Great video. The audiophile in me loves geeking out on this kind of stuff

Amazing System. I have never seen anything like it on the planet

i had just about every physical felt with , i still recall earthquake 70mm six-track sensurround at , abc screen 1 , bournemouth feb '75 , 8 year old . saw it 4 times over many months of half year it ran for . i even recall first experience of lucasfilm ltd THX sound system after reading about the hype of it since 1988 and experienced it , after seeing "indiana jones and the last crusade" 70mm six-track Dolby Stereo SS format 43 , 3 times at abc screen 1 , bournemouth so i was very familiar with the soundtrack then saw it world famous CIC Empire Leicester Square , london , twice in lucasfilm ltd THX sound system . oh , difference was thee true night and day . so is that what i was missing on the soundtrack ? in terms of feeling it , feeling it . i mean feeling it . then saw another movie at another THX cinema at CIC UCI high wycombe , "arachnophobia" in Dolby Stereo SR format 05 and the THX JBL sound power was out of this world . a friend that took me there , said it was voted 8th best THX sound system cinema on the planet ! sadly no THX cinemas exist in the uk anymore . I use JBL professional cinema pa used and ultra cheaper than JBL synthesis . most JBL synthesis on ebay hardly sells . it was overpriced in my humble honest opinion . may use of use some parts used in actual JBL cinema pa systems and the JBL cinema systems i would buy that over synthesis as JBL pa cinema has actually been used in cinema . having worked as projectionist decades ago now retired . started with UCI cinemas and lastly warner bros . UCI tower park like few other UCI sites used experimental overhead surround and that was 1989 , with Dolby Stereo CP55 with SRA5 all 35mm vic 5 projectors with EV speakers LCR and overhead surrounds , no subs at the site thou typically required for SR soundtracks . my JBL system 4673A five screen wide with 2 to 6 or 8 subs x2 JBL 4645/c 2x JBL 4682 TCB , or i can use two inner channels Le Re for subs to do "star wars" or "close encounters of the third kind" used for different , special sound format presentations that no other home cinema can do , not even a trinnov . yeah , try doing that at home cinema . x11 JBL 8330 mkII that can play many surround formats including the original left-half right-half , something no home cinema can do . it can also do CBS and 6.1 , 7.1 or atmosPlusIIIx beyond . i know what to look for , listen for and feel for . overhead surrounds x9 JBL 8330A that uses world first DOG channels anywhere on the planet . most use overhead surround and no they are not atmos channels . atmos is merely new codec encode/decode of extracting discrete more channels . "overhead surround" . also world first anywhere on the planet i think the vastly infinity of the expanding universe ? "below matrix surround" . an idea i came up with since 1998 . oh , and CBS centre back surround , came up with that idea while in projection booth at UCI and that was 1989 as i was frustrated with phantom sound on the split-surrounds while watching at another cinema that can show 70mm , "indiana jones and the last crusade" . i put my idea into motion 1998 with dts laserdisc of "goldeneye" using x2 sidewall and x5 CBS back wall or centre back surrounds . nearly a full year before dolby labs announced "ex" of course dolby labs got the idea from me , with 30 min long distance , 9pm uk time to new york , eric kristofferson who was more than interested and therefore dolby labs , steal my idea with not even crediting me for the discovery idea . i was , ex professional projectionist that knew what to look for , listen for and feel for with movie soundtrack content . system 15.12.2/6/8 and beyond 38.000kw THX using the actual cinema , lucasfilm ltd THX sound system 3417 . a common denon avc-x8500h integrated with some classic cinema sound processors , Sony SDDS D3000 and the best of the lot , Dolby Stereo CP200 made released in 1980 , regarded best cinema processor ever made and very rare , and still in use at selected cinemas today . if i had passport i would fly over just to listen to it with content/movies of some that i heard in THX . if the line-array speakers ain't playing the movie soundtrack as discrete as LFE.1 should only play the discrete not have all the bass from the discrete channels mixed into it . there is only time bass is diverted to the subs is with Dolby 4.2.4 bass extension . i heard when talking with projectionist at UCI high wycombe early around 2000 on phone , that two JBL subs was used at THX cinema . x2 ? i still find that hard to believe as that THX cinema vibrated my body , with screen channels bass as well and surrounds ? bass with "arachnophobia" was pressing felt against my face , my upper body , lower part of my body , jeans/legs even my feet was feeling it in my shoes . i saw the same movie at preview show 1989 at odeon screen 6 , bournemouth , didn't expect to see it again jan 1990 in THX . i have idea to do my whole room as speakers since most cinema professional pa JBL are cheap , as the surround channel is still not fully covered , i mean fully covered but still wouldn't be cheap even thou it is cheap , wouldn't be cheap but it i would design new surround formats for the surround channels . i am ex professional retired projectionist and i would even go beyond my own expectations . then again there really isn't any it's case of willing to doing it . sound air particles in real life , i know what it sounds like . most movie mixes often never even get timber matching of atmospheric airy outdoor sounds correct . the tone of surrounds vs the LCR mix the sound of even rain effects even sounds out of tonal balance . and rain effects with these , atmos mixes ? really ? rain is complex effect to mix and mostly the rain is heard at ground level as gravity is pushing it down to landing on multiple surface objects . even underwater movies never get the sound frequency pressure correct on the body least of all the ear and even so would be extremely uncomfortable as small less than teaspoon small drop of water resting against the eardrum would be very uncomfortable . audiologist tested my hearing years ago , used water and ultra sonic to test . even when i use ear-drops , it makes me feel uncomfortable . earthquakes . now that is a complex sound to do it right ? a sub bass won't do earthquakes correctly . even "sensurorund" really ? i doubt very much bass is going to come up at me in vertical angle and press against my body . more like the floor violently vibrating and slowly walls breaking apart due to the tremendous forces of the earthquake buckling the walls and flooring . sound would pass though the building since , earthquakes happen many thousands of feet or few miles down under the earths surface . i have an idea figured out but the use of it would be only good for certain movies ? i think at times i'm taking home cinema a bit too literal , lol . a truck l, lorry or bus passes along side on the road while walking on the pavement . i know how that feels . yet can a movie soundtrack reproduce it ? i even brought that overrated movie uhd atmos "ford vs ferrari" 2019 , a total waste of my listening time . the cars drive-byes sound/feel nothing like and even if could would maybe knacker the amps/speakers and the amount of square foot of air it would have to push which would be near to impossible . movie mixes have competition to mix with the three elements of the soundtrack DME dialogue track , music track , effects track , some element of the tracks would have to be compromised and all mixes use compression . otherwise the sound would wreck the amps and speakers and once at 0dB there is nowhere else to go that's it's limit . and the mid to highs on some movie mixes is often harsh dB deafeningly unrealistic and would result in possible HF hearing loss . i can still hear high frequency pitches up 16,000KHz on few rare movies where a fundamental sound effect pitch reaches up 18,000KHz , "alien 3" 1992 . the germans i think was doing tests with infersonic to see the effects on people . makes my skin crawl . so You're the system can 8Hz ? lol unless in nature it can do that ? well even if walk around i'm sure i can feel it lower than 8Hz . i done many psychoacoustic tests using ear-plugs to see what i can hear to feeling and it is like , just like using a dsp crossover . my cats can hear or google says 40Hz to 90,000KHz and that doesn't mean they can't feel say 20Hz when laying on my cinema seats with bass shaker transducer now . then again my JBL system reaching 20,000KHz or fraction over at 22,000KHz must surly annoy my cats and would be easy for them to hear that tone pitch . humans , meh , unless your under the age of sweet 16 which is roughly where hearing range rolls off at that age .

That's amazing. I've never seen this deep knowledge and skills in sound. I applause you sir.

“The only room in history that does down to 8 cycles”. There are multiple dozens of rooms that play down to 8Hz or lower on AVS forum. One guy I’ve visited in Virginia had 16, 18” subwoofers in his ~1500 cubic foot theater space, and could make his French doors in the utility room next door shake 6” on a 7Hz note from the movie Black HawK Down like a poltergeist was trying to get out. I’m not knocking your room or your work, it looks like it’d be really neat to visit, but just countering that initial 8Hz stand-alone claim. Also as to the dual opposed subwoofer design. Multiple internet direct vendors have done that long ago as well. Epik Empire, Seaton Submersive HP, BossoBass Raven as a few examples of inert cabinets based on dual opposed subwoofer designs. Here is the video of popalocks room showing a 7Hz cycle from the scene I described. Timestamp 15:30. kzfaq.info/get/bejne/op1_i5mdkp-4iIU.html

What about Atmos? Are you guys able to implement Atmos into this system, that's the only thing I see missing from this system. Other then that, it sounds amazing!

Now, all we have to do is find the unlimited money. 🤷‍♂️

This is the future of sound entertainment.

Yes, infinite line is definitely a good way to go. My lines are 9'-8" tall but they are open baffle CBT, not infinite line. My woofers and subwoofers are mounted magnet to magnet to cancel mechanical energy also, this does work really well. As a test I stood nickles on edge on the test baffles for the 18" drivers and they didn't fall when cranked up with a 16 Hz tone. As for the reversing to cancel even harmonics, I did that from around the late 80's until just a few years ago when I decided I would rather keep the even harmonics to help mask any odd harmonics. It's really open to debate which route is best and of course it also depends on the harmonic content of the drivers used, reversing is probably best in some cases, not in all cases. You definitely have a unique room there, very well engineered! I thought I put a lot into mine but this is definitely... actually a little beyond, "next level". I'll send a link to this video to Don Keele, I think he will enjoy seeing this.

i really like this theatre.\I WONDER HOW MUCH THIS COSTS$$?

Pretty cool home theater. How does music sound though? Did harmon’s study show people liked reflections for music?

Can your environment playback all surround format Dolby Atmos, Auro 3d

hello from France, here is a very great information about the JBL SYNTHESIS, the best very high fidelity sound system made from pro sound technology where JBL is the world leader "pro sound comes home". I have not well listened the name of the creator, a very great engineer !

Ascendo makes a single 50" infrasonic sub that plays 136db continuous and 140db peak. It's advertised to pay down to 5hz, but it'll play to 1hz easily. So just put two of those in a room and nothing could touch it. I am a huge fan of live array and hopefully someday I can make it out to demo this room

Lot of nonsense here. Of course the sound reflects off the ceiling and floor. Even the baffle wall affects the sound. A slotted diffuser does not "spread all frequencies equally". I can't even get halfway through this video.
