Are those where the speakers are also placed on the sides of the screen.
Both at Home and at the CINEMA.
When you place the three speakers DIRECTLY above or bellow the screen you will get cancellations in between the left and right channels that smear the stereo imaging.
If you place the left and right FLANKING the TORUS hang on for the ride of your life.
The Center channel above or bellow works quite well though unless you have reflections from the back wall which must be absorbed.
There are three types of AMC TORUS THEATERS, the Best is the Older Larger Squarish SDDS 2.35 theaters with a slight slant and the screen up 10 feet high. On sdds there are three speakers on top and two on the side. These theaters present the best compromise between picture quality and sound quality.
The smaller 1.85 rooms have the screen occupying most of the front wall, except with a piece on the side where the exit door is.
These rooms are my least favourite except for SHREK where the image was good. The worst flick in 1.85 was jurassic park three.
These 1.85 theaters have less powerfull lamp houses too.
The latest incarnation of TORUS is the Magnum 2.35 Stadium seating occupying the Entire front wall. Sadly, the final incarnation in Large Venue. There will not be any more new TORUSes in Movie theaters in the foreseeable future, probably ever.
This is the piece the ressistance for the VIDEOPHILE, that follows protocol. See PROTOCOL Bottom.
Case in point last night at the SUNSET 24 in Miami, K-Pax. A visual enjoyment like only the Torus can offer.
The sound? If the entire front wall is a concave structure obviously, you don't need a Russ Herchelman to tell you that there are going to be problems.
The anamorphic 2.35 really rocks on the TORUS
David, Mon Ami, To be perfectly blunt: A one way curved screen is a piece of crap, it creates a vertical hotspot in the center. It may sound good and look cool while you project ciclorama lights before the movie but it does not do didly squat for the actual picture quality.
An example of a great sounding Movie Theater with the TORUS is the Older large Squared rooms with 50 foot wide 2.35, high on the wall and 2 speakers flanking.
PROTOCOL FOR WATCHING A TORUS MOVIE:
Call ahead and (LIE) inform the management that you are fed up with their projectors being out of focuss, that you are coming to see such a movie and that you expect it to be perfectly focussed.
If you cannot get a hold of the management by phone , make your request in PERSON.
Poorly focussed 35 mm projectors, benefit from the screen perforations of the CINEMA perfs screens to create a pseudo-sharpness. Somehow this phenomenom that I call NEGATIVE LIGHT MATRIX works well in the Brain. Not unlike the Fresnel lenticular Black Matrixes used in rear projection.
The TORUS screen does not have this negative llight matrix effect.
THE WORST ENEMY of the TORUS screen, the finest screen for front projection is TEREFORE: a slightly out of focuss lens.

Find one near you and ask if they have the Torus. Only 550 of them do.
It certainly sounds like the one in SWEDEN does have it. With the very curvy sounding name like "Kungens Kurva". :) The one in Dunkerque sounds like an awesome theater but I see no reference to the curve. Good luck to those who call.
If you do follow the protocol, you will be pleasantly surprised.
