The screen and sound was my proof of concept - to make sure that a) it would work in a room so small and b) that we would use it enough to warrant making it better. We used it for a few months and really enjoyed it. This was really low budget stuff, the pj was <$500, the Samsung HTIB was donated by a friend, we had an old futon (in front of the sink so maybe 7ft from the screen) for seating but you know what - with the lights off and a BD playing on the 82" screen (even though the pj is only 720p) it was a great experience.
So now we want to make that experience better - we ripped out the sink/counter to let us move the seating back but left some cabinets and counter space on one wall for storage and a snack bar, ran the rear speaker wires and HDMI through that old plaster wall then put drywall over the plaster (never done drywall before, what an experience that was). The Qumi projector doesn't have a remote control for the power (WTF Vivitek) so I replaced the soffit light with a recessed media box (2 outlets + space for cables) so I can control the PJ with the old light switch - wiring is all new romex with ground etc so no worries there and since the PJ is LED there is no cool-down period needed.
So that's where we are as of today - we need to figure out something for the floor and deal with the obnoxious fake tile board that is halfway up every wall, and the even worse wallpaper that covers the rest. The floor right now is green and black carpet tiles but as thebland said I can probably get a remnant big enough for quite cheap. For the walls I've pulled off that tile board and it left behind a mess of construction adhesive and broken plaster.
I guess I'm really looking for ideas of what I can do to make it more theater-like and less 70s kitchen-like
Ambient light is under control, I have 100% blackout curtains for both windows (and they are needed since the Qumi is only 300 lumens). Any thoughts of what I can do with the walls (specifically the crap behind the tile and the wallpaper which won't come off easily)?? Drywalling every surface really isn't an option although I know that would probably solve a lot of my problems. I thought about carpeting the bottom half of the walls....I know movie theaters do it and it would certainly hide the crap that's there now
Any help or ideas would be appreciated, I know this forum is usually geared more towards people who need help with sound reflections/dampening, risers, stages etc but hopefully there's a place here for people like me...
