The proof is in the pudding. I studied over 30 torus installations to deconstruct the causes or absence of the acoustical anomalies, I also have 5 STEWART torus installations under my belt and 17 Biener solid 8 foot wide Parabolic screen installations- since 1989.
Phoebe (commissioned in 1993 and now placed on market by new purchaser Pharell Williams).
Due to the white pearwood acoustics, this one was a toughie,the jbl synthesis one is harsh in here, also concentrating all the speakers underneath the high aspect ratio screen 1.66, gets the sound creeping up into the parabola.
That is consistent with my findings in smaller AMC auditoriums that had a wall to wall 1.85 torus, the HIT sound system would image poorly within the parabola.
I did find that in AMC rooms were the left channel and right channel flanked the CINEMASCOPE screen the experience was phenomenal, best in class imparting a 70 mm depth and richness to the image and the impression of highly increased resolution. It's because of the amazing evenness of luminosity coupled with the higher MTF of the screen. Why are you saying lesser resolution? (you are completely incorrect there).
Barrel distortion effects are minimal unless you are playing video games, in fact having the screen shape coupled to the eye is the most organic form of screen projection, you would have to see it to believe it. I sooo spin your disadvantage into a Primordial Necessity, you have no idea.
FOR A NON-TORUS EXPERT, proclaiming such negative statements about it without even understanding it is irresponsible. In the future such comment would be akin to being a flat earther or worse a book burner. Because the torus is the ultimate man machine interface in the age of the new literacy.
YOU ARE WRONG to critic based on 2 criteria whilst ignoring 20 others (many still not fully understood psychovisual phenomenae).
Let me show you my cadre:
ATLAS is an incredible sounding audiophile room, Perfect, it has a TORUS. Kitscher than a northern European bordello but best torus sounding room due to all the dampening.
PROMETHEUS was documented in a thread here in the DCI sectrion.
I returned from London last week meeting with ZHA architecs where owner of SKOLL and the upcoming ALBIORIX selected a 2-1 aspect ratio TORUS for his 3rd commissioned cinema: EUROPA (after also seeing PROMETHEUS and PHOEBE).This is significant because EUROPA is a moon of Jupiter not Saturn
If ALBIORIX doubles up on the SKOLL technical experience by a factor of 2, EUROPA does so by 4.
In fact the goals in EUROPA are to recreate reality, no stops will be pulled, THAT MEANS A TORUS as the center piece. With the first moon of Jupiter we are creating a far more elevated standard of performance that seeks an obscure new frontier of what Spectacle means. EUROPA's portfolio of features delivers a rich pallete of so subtle nuances, again many not fully understood phenomenons but that bestow a significant contribution to the recreation of reality: Torus, passive dual projection 3D, autoconvergence among projectors, special lens proximization optics for dual projjectors,4K, special lenses,new more subtle sigmoid gamma curves,teranex 2d to 3d conversion, HFR, Dolby Atmos, 3D front speaker Trinnov DSP processing, Custom Quested monitors Farfield and specialized ATMOS purpose monitors, a new generation of cinema chairs with built in ipad minis with food and beverage concierge features (delivered to each chair), and finger print readers for access to controls and seat comfort memories, air conditioning or heating blowing from seats, exact center of gravity D-Box chair endoskeleton. And last but not least twin Rotary subwoofers.
More Improvements on our already new improved CINERAMAX higher back Strato seats.
Cinema for a spaceship house in Moscow.
And here is Trumbull's Lab's Torus.
