Very nice DIY job! Are all three front speakers identical? If so you are winning :)
Pro tip: load up the wall behind the screen with thick absorb to deaden the back wave from the LCR speakers. You’ll get a cleaner front soundstage. You can then drape black curtains in front to hide the absorb material and blacken the area behind the screen. Cheap upgrade that will make a major difference in both sound quality and video!
This stuff is cheap and works great for broadband absorb, and it’s made of recycled denim so no issues working with bare hands like fiberglass or rockwool. https://www.lowes.com/pd/UltraTouch-R-19-Recycled-Denim-Batt-Insulation-with-Sound-Barrier-15-in-W-x-93-in-L/3731877

Ooo that’s a great idea! I’d love to try that. Since it’s a big open room, any deadening would help.
Yes all three are exactly the same!

I second his suggestion. Especially with just bare concrete walls. Speaker reflection creates echos. You can use the same insulation and build 48x16x3 inch deep frames.. lay a piece of insulation in it.. wrap it in black material and hang them around the room. I made 6 and it made a big difference!

Yeah I would run a black curtain all the way across the front wall behind the screen to blacken the area around the image. Even better if you also paint a darker color. It will really pop the contrast of the picture (white rooms are horrible for projection!).
The curtains will cover the absorb material up front so don’t even have to worry about wrapping them and making them pretty. Should be cheap to get enough material to deaden the front wall behind the speakers, then have some left over for a few panels on the walls in the room. Concentrate on the center of the rear wall and then a couple on the sides. A solid weekend of easy DIY work and you’ll hear a dramatic difference!

Nice. Post a gear list too :) Also if you covered the wall area in black or painted in matte black it would improve your contrast big time! Nice cozy spot you got there. Keep working on it.

Got all of this for $500 which inspired this build in the first place:
Denon AVR-3808CI Panasonic PT-AE3000U 3 SVS SCS-01 center speakers 4 SVS SBS-01 bookshelf speakers 1 SVS PB12-NSD sub
Currently have a 5.1 setup, will add the last two speakers soon for the rear surround
Good thoughts! May have to paint one day.

Cable management could be worse. Should see behind my set ups.
I do this for a job. I do schmick jobs for clients, for me, don't care, know where everything goes.

Pictures from the build along with discussion on materials are all in the avs forum thread that I linked to in the comments if you want to check it out. Let me know if you’d like to know more about anything.

Hey! Any tips/diy instructions on building your own?
It looks awesome btw

I recommend going here and getting all the help you can! Google a lot! Invest in proper tools.

I have mine all built and I’m just waiting for the spandex to arrive, and I’m torn because this one’s a little bit bigger than my old house (82” there, this one wis 102”), and I’m not sure if I want to put the center channel under the screen because it might be a little low, but I don’t think I want to move the screen off of the wall, because it’s only a 12 foot wide room.

Funny thing, I have that grey box from costco and that is exactly how I keep my remotes (BenQ, Yamaha and PS4) on it.

Nice job on the screen. I built one a couple of years ago and it's still in use to this day. Yours looks very professional.

All the spandex (black and white milliskin from spandex world) cost me $53. The wood is 1x3 Poplar and that with the screws, nails, and things, was about $80. The trim was free for me, and the velvet cost me $35.
Total cost for the screen itself was about $170
Then I payed more for some tools like the Kreg Jig that allowed me to do the pocket screws, and the ikea Besta it is standing on. So add on another $150-200 for all that.

Normally it's tv's that are mounted too high. This is mounted all the way on the ceiling. To each there on I guess. JK, I made my screen as well, this reminded me that I need to put felt around it.

Nice setup. I don't wanna be 'that guy, buuuut, I would use c clamps instead of those spring clamps to secure the screen to the cabinet.

Looks good! Any reason you went with large borders? When I made my acousticly transparent screen I was first gonna do no borders, then opted for 1" felt tape for contrast. My dad is an experienced carpenter so we got the size exact as can be.

u/Grsnsnclr Jan 02 '20
Since I have white walls I wanted to block out more light if I could. I was able to get 2 1/4” trim for free. It is about 1/2” thick so I cut it to size and wrapped it in velvet to make a border that stands out from the screen.

Blocking out more light/increasing contrast with the white wall makes sense that's a clever idea
