After many years of experimentation, I believe the aim should be to create the most absorbing experience possible by correct use of sound & vision. | | Following on from principles in part advocated by Jim Fosgate, I believe in a 360degree soundfield where ideally the room wouldn’t be square but round where 7.1 is the minimum. |
To not only replicate a good cinema,but to go beyond!
"In real life, we're used to hearing in a 360º sphere from all around us. Stereo is unnatural in that it is coming only from the front speakers."
Now,few have a round room,so specific room treatments can be applied to reduce what I call the “boxy sound” of a square room and to more closely emulate the sound characteristics of a circular room.
In addition to this, movies are mixed fairly “bright” to take account of the fact that-as in commercial cinemas-the front L/R/C speakers are behind an accoustic screen.
This is the ideal placement for the front three speakers and ensures that the sounds come from where they were intended to come from on screen .(The brightness is slightly tamed by passing through the screen material. )
So, with speakers not behind a screen, soundtracks can sound too bright, behind a screen the sound is closer to how the original sound mix was intended-this is my preference and what I advocate for Cinema360 systems.
For the speakers my preference is horn speakers (similar to what's used in top commercial cinemas) and after years of experimentation I have found what I consider the perfect speakers for Cinema360 and Indeed perfectly suited to compliment movie sound mixes of today.
The screen of course should be a 2:35:1 ratio as most movies are 2:35:1 and not 1:78:1(16:9),16:9 is a t.v. ratio-a compromise ratio and one that loses 33% of the pixels of that 1920 x 1080 projector/panel in the black bars above and below when watching a 2:35:1 movie on a 16:9 screen.
I prefer to use ALL the resolution of the 1920 x 1080 panel for 2:35:1 screens.
This means squeezing and stretching the picture by use of an anamorphic lens. This in conjunction with 2:35:1 modes now found on projector and video processors ensures that no resolution is lost.
The screen itself-where possible-should be curved,there is less light lost from the screen with a curved screen as the light is reflected back to the seating locations NOT the side walls,this allows for larger screens in rooms.
Cinema360 setups will calculate the best sized screen for your environment, the ideal seating position for maximum immersion in the movie and ensure that although the SMPTE (50 years old) cinema recommended standard was 12-16ft lamberts of brightness- to reflect back from the screen-, this was a film standard, more a technological limitation of the time as opposed to a realistic ideal for today.
Cinema360 projection will aim for 18ft lamberts to achieve a bold, dynamic picture with a more accurate colour range and 25-30 in a non-dedicated environment. (*For comparison, a plasma produces about 30ft lamberts.)
This precision is mandatory,and is critical in maximising your setup.
I will tailor a setup to your viewing preference-if just a dedicated movie room for example-my suggestions would be different than a sports based system-or maybe a system that is good for both for example.
Cinema360 is a concept that includes total synergy in all sound and vision aspects-a synergy that uses the best cinematic “knowns” –some of which before, have been to costly to replicate in the home.
