The main question I have is regarding my screen options but I thought I would give a little background in case there is other relevant advice.
Just moved into a new home and part of the prerequisite was a space in the basement for a home theater. The new house has a space that was previously used as a gym that will work. The room is finished except concrete floors. They had rubber matting down. The room is nearly light locked. The doors have glass panes that I plan to cover somehow.
The room has the following dimensions (LxWxH): 17.3 ft. x 10.9 ft. x 8.9 ft. It's a bit smaller than I would have liked but the house was otherwise perfect for what we wanted.
I plan to repaint in greys and build a riser and carpet the floor. Insulation in the riser for soundproofing. 2 rows of seats with 2 seats in front and 3 in the back. As far as a projector I plan to go with an Epson 4010. There is a closet behind the theater and I am considering placing the projector in there and cut open a hole to project through.
11.1.4 Atmos with in-ceiling speakers and bookshelf speakers for surrounds and rears. Front speakers will be towers. At this point, I'm leaning towards Klipsch RP-8000f with RP-600M as surrounds and rears.
I had originally planned for a traditional center speaker until I started researching here and there was a general consensus that a 3rd tower for the center is much preferred over a traditional center placed below the screen. I like this idea but it changes things drastically and that's what led me to this post.
After a bit of research here, it seems I have a few options.
1. Drop down electric screen. I would need an acoustically transparent screen and preferably tensioned. A bit pricey at this point given my budget has grown
Nothing would be behind the screen so I don't need the screen to retract.
2. Build a false wall and place the screen on it. Do I place the RL towers in the false wall?
3. Place a curtain on the wall and extend supports out to have the screen "float" Sort of like this.
I'm thinking option #3
but this seems less mainstream. Don't want to ruin the theater by going down this route and it looks out of place.
Also any advice on screen size? A 120" will fit and give me just over 12" on either side. Not a lot and that puts the towers against the wall, though I will angle them in a bit. Was reading a post were someone went smaller and regretted it and they gave the advice to go with a larger screen size.
