Long time ago I used this forum to calibrate my screens in a suboptimal setting (living room with lots of echo)...
Now the time has come that there will be a big chance I am able to start a new-build (house), therefore I am free to create a cinema room (Home theatre room).
The idea is to create a room with the ability to place 2 rows (first row 2 seats, second row optional 3 seats).
First row will be primary seating position.
Furthermore, the room will have an LCD/OLED! (This because of HDR & 4K). This limits me to max 70 inch diagonal. Effective screen will likely between 60 en 70 inch, depending how affordable at the time the house is finished (1.5 year from now).
Seating will be adjusted to this screen size!
Ideally the room will have max dimensions of 5.5 meters length times 3.0 meters width and 2.6 meters high.
Currently I own a 7.1 set and in the future wish to upgrade/expand (did not invest the last couple of years due to lack of good space). I have been reading about 9.1.6 to 13.2.
See also attached picture.
Furthermore, I have been reading a lot about seating distance. From Visual Acuity vs SMPTE vs THX...
Then I read:
Since I am planning on using an LCD/OLED, the above link is the "only" real source (often mentioned in different forums) which is dealing with 4K distance.
For a 70 inch this would be: 5.8-8.75 feet (first row 1.8 to last row 2.7 meters), which then in turn would not exclude a projector (since I have a room of 5 meter... in length), but for now I use the 70 inch as a guideline, I can always adjust accordingly.
And last item I read a lot about is isolation (soundproofing). The house I am going to build is using "hollow" blocks for better heat and sound isolation. I read a lot about deflectors and absorption material.
Lighting is done with a lighting architect and will probably be combined with a KNX domotic system.
My questions would be:
- What would be a wise audio layout to prepare a cinema room for?
- The atmos speakers(ceiling), how does this work with multiple seating rows, how to position/guidelines?
- "Correct" seating distance for an 4K HDR screen (5.8-8.75 feet (first row 1.8 to last row 2.7 meters))?
- Is it advisable to place the receiver inside the media room?
- Is absorption/deflection material needed?
Based on the above questions I will sketch a room layout and will post the results back here to confirm and get more feedback. Since we are building in The Netherlands with stone building material it is not easy to change it later on, so first time right would be preferable
If more info is needed please let me know.
