Who want to close the shutters when the view is so nice 
Was taken while we were still building,
Plus a cool lightning that I caught during a big storm,
Cheers

While we are not talking about paintint anything beyond the ceiling I see no reason why a spare bedroom that is primarily used for theater cannot have an exceedingly dark color pattern. Is there something in your covenants? |
Just the covenant between man and wife that keeps us a couple.
Its not so bad that she left me when she said no way in hell is that monstrosity going up on my ceiling several years ago and it mysteriously found itself up there one day when she was gone. But she put her foot down on dark ceiling; the most I could go to is Behr Silver screen or whatever paint it is the DIY's use to get better blacks for LCD projectors ( a fairly light gray)
But I should reflect on my answer and change it to I am working on it. Once I find the magnetic strips or whatever other easy method to install easily removable panels with black felt covering I will have the critical part between pj and screen masked.
I do have adjustable masks for the screen and they did make a huge visual difference in framing whatever I am watching. My biggest complaint on that was that although I purchased a simple wide black window shade, the reverse side is white so I need to add a panel to hide the roller which shows the white vinyl on back side. |
The point was that if you are not going to create an environment to take advantage of two of the strongest CRT benefits (Black Level, and On/Off CR) then why bother with CRT at all? LCoS will come close to that film-like look but without the benfit of BL/CR, yet bring the lumens for non-dark environments.

I am almost there, especially considering I principally watch BR movies at night when the light streaming through gaps in the venetian blinds and dark curtains is not a problem. With black felt covered panels between pj and screen I will be there for all practical purposes (that light on ceiling reflected off screen and backside of my black upper screen mask roller is really my only problem for BL/CR - which can be faintly seen in one of the photos I linked to above) http://picasaweb.google.com/Ralpharchi/Homehteater?feat=directlink
I may go LCOS anyway, my wife is ok with that if it gets the Marquee off the ceiling. But I have really good condition tubes and its hard for me to spend $2-3 k at this time with the great picture I have now. Better to invest $100 in felt and panels and keep the light gray ceiling.
Actually what will drive me to digital is something entirely different. With current pj, upon fade to total black or almost black, I am getting some distracting sets of wavy, dancing lines on screen that are barely visible, but enough to be annoying. Under these conditions any light, such as the light you get from hitting the brightness control or other menu item, or one area of screen with something fairly bright visible, will make these not visible. But they are a distraction during the supposedly best time for a CRT.

Start a new post. There are quite a few Marquee experts here. I'm sure they can help you nail down the wavey lines issue you see in fade to black.

When I finally repainted my theater, i started with the wall behind the screen, and that alone made such a dramatic improvement.
I would order them:
1. wall behind screen
2. side walls
3. ceiling
4. floor
5. rear wall
My next project is to finally make some masking panels for watching 2.35:1 movies on my 16:9 screen, and I am totally psyched about how that is going to look. Hopefully I'll have those done with pictures in the next week.

Carl - nice theater room -
related to covering white ceilings; the acoustic panels you placed on ceiling could perhaps be a better solution for me and others than something like black velvet/felt covered foam panels. What do you think of this as an option? Do you know a supply that has these in black?
Would it be a mistake acoustically to have these panels only in the area between screen and projector?

Schmoe?  (looks like a missing /quote tag)
Thanks, I do love my theater, as do all of my friends.
I would definitely make or buy proper acoustic panels rather than wrap foam panels in velvet or felt. You'll get an acoustic improvement from eliminating first reflections, as well as a visual improvement from the darker area on the ceiling.
Any first reflections you can eliminate will improve the acoustics.
There are a number of companies that make acoustic panels. I decided to make my own using Owens Corning 703 for acoustic panels and 705 for bass traps. I enjoy projects like that, and I saved quite a bit of money doing it all myself.

My screen with my dark red ceiling with black velvet surrounding the screen: 
the black around the screen was probably the biggest improvement to "enjoyment", followed by the sidewalls directly next to the screen, then the ceiling and finally carpet on the stage. My ceiling still reflects some light, even though it is a flat paint. I might go flat black if I get a chance.

I have veleveteen on left and right walls, same material completely surrounding the screen (fixed with 1.5" valcro) and to finish I painted the pink rigid foam (from Home Depot) flat black and merely screwed this to the ceiling ahead of the screen.
All easily removed if so required, such as a house sale. ometimes even I wonder whether the pj is still working when pic ftb in movies.

Carl,
How did you determine the first reflection positions in your theater (blue tape marks on the walls). Was it mathematical or the result of somehow listening and moving something absorbent around the room? I am curious
Thanks,
Dan

Hi Dan, i'm not carl but hope ill do.
Above 400hz sound reflection ispretty easy to figue out.
The easiest way is to use a mirror. sit on ur sweetspot and have a friend walk down along the sidewall with the mirror up against the wall at tweeter hight. when u can see one front speakers tweeter in the mirror mark its place on the wall behind the mirror, walk further down along the same sidewall until you see the center speaker, mark it and further down til u see the other front speaker and mark that as well.
that area between the markings is where the first reflextions happen when u sit in the best seat of the house, if u want first reflections from all the seats, just do same procedure from the seats furthest to the sides.
do the same thing on the other sidewall and on the ceiling and on the floor if u don't have a carpet between screen and sweetspot already.
best regards
bent
