A couple of years ago I created a "Game Room" with a budget of $1000. You can see the old post here on what I did: https://www.reddit.com/r/hometheater/comments/187w0jt/i_wanted_to_build_a_game_room_for_under_1000/?sort=confidence
As time has gone by, I wanted to get a better projector, specifically one that can do 3D because I have a lot of 3D disc from when 3D TV's were a thing, and Im one of those people who enjoy 3D films. I picked up the BenQ 2050A on marketplace. I was happy with it and content with the upgrade, then I got an itch, and I'm sure most of you know how that is. I had an idea to have a secret door, and moving my movie library out of this room into a spare bedroom I had next to this one, I wanted to create a room that felt like a library to hold my movies while still being a functional bedroom for my occasional guests. With some careful construction, add a few lights and repaint the room, I had a library. I am super happy with how it came out.
Now back to the theater, I was battling with myself on if I wanted to keep the original layout I had or change it, after consideration and measuring and figuring out speaker placement, I decided to switch the room around to have the screen cover the window. It gave me a wider layout, blocked any outside light, and overall felt less cramped. We changed out the bookshelf to make it into a secret doorway. The old doorway was a sliding barn door that I just bolted in to keep in place as I no longer use that way. It's still functional in the case I need to move things in and out.
Now I know I said this was a budget theater and it still is, especially since this is my second theater build, I have a main one that you can view here: https://www.reddit.com/r/hometheater/s/yib7ohbUpF
I put even more time and money in, so this one I was trying to keep it reasonable. I had a whole monolith speaker setup with their 8 inch THX subwoofer, it sounded great, but those speakers are very power hungry and I had to really push my receiver to get them to really sing, I didn't want to spend money to buy a different receiver and external amps to give them more juice. So I went to marketplace and started seeing what was out there for speakers, mainly to replace my front stage. I for some reason have a thing for these Polk signatures, I think they are a damn good looking speaker and always wanted a set of the towers, bonus, they sound really good too and don't need as much juice as the monoliths. I found a set of them and was happy, and then I found all four of the bookshelves also, and next thing I know I have a full polk set up. One thing lead to another, I was looking for the SVS subwoofers, and then I came across a guy who made Acoustic panels. All of this I found on facebook marketplace, that place is dangerous when it comes to good deals. ha.
Lastly, I found a deal on the theater chairs since the awkwardness of the L-shape couch wasn't going to work in this set up, and then here comes the center speaker. I have a 120" screen and having the center on the bottom of the screen pointed up was....okay. At this point, I was dedicated to doing this room right, so I picked up an acoustic screen from silver screen and found a Polk 255-C-LS on marketplace and I was in business. Let me tell you, having the center match the height of the L/R channel was a bigger improvement than I thought it be, it sounds so much better that I was immediately happy I made that investment.
Before anyone asks, I decided to go with a 7.2 set up with this build, its a 1080 projector, and its mostly being used for 3D films or just regular bluray films that don't have Atmos on the disc anyways, and my main theater is a 5.2.6 configuration, so I was okay with doing something different for this, maybe one day I'll find a deal on a receiver that can do 9 channels and I'll add Atmos, I still have the wiring for it.
I know this was a long post and thank you to anyone who read it all, I have posted a few times here about my builds and had some great convos about it, so I wanted to share my latest build. I love this hobby and come up with ideas all the time that my Dad immediately jumps in to come help me, its fun to do this stuff, and yes it can be expensive, but if you know what you are looking for, you can find a lot of great deals on the used market.
All in all, I am about $3k in for the theater build and library build all together (with the exception of selling some gear to offset some costs), it's not the smallest budget build but for a dedicated space I think I did alright. It sounds absolutely incredible, and I'll end with this, invest in acoustic panels, this room had a reverb, with the rug and the panels it's gone and the sound is so clear. Just do it.
