If it was me, I would be looking at covering the wall behind your screen anyway with some sort of absorptive material. You could use that opportunity to mask the crown behind your screen. Alternatively, you could fill the empty area in the top panel with cardboard or foam insulation to prevent light reflecting through.

Moving this discussion over here...

Looking through your pics, honestly, I don't think i would worry about covering the crown on the soffit just right now. I think it's a nice detail and it would be easy to do later if you found to be bothering you.

An acoustically transparent fabric like GOM would be the first choice. I'm not familiar with DMD, but that also looks like it should work well. Speaker cloth like the Rose brand stuff will do too. It will be a little thinner so more acoustically transparent, but also more light transparent. If you are planning to put your speakers behind your side panels, I would go this route. If they are going behind your screen, then look at GOM. Velvet will block all the light and most of the sound. I've been happy with GOM for my screen surround.

The bottom panel will cover my sub(s), the LCR will be behind the screen. I could make the side panels out of velvet as they do not truly need to be AT.

Wraunch,
Love the room thusfar. Quick question, If you are doing AT with that door on the left, how do you plan to close off the side (behind the screen) while keeping a border around the screen itself?

I will have a panel to the left of the screen that will have a slight L to it to wrap around the corner and give the screen a 2-3" border on the left edge while creating a panel to seal off the back of the screen. That panel will be attached with velcro. At least that is my plan currently but I'm open to ideas.

I think this is a solid plan. The only thing then will be keeping the velvet clean. You can usually get coupons for Jo-Ann fabrics and save a little.

Love the progress pics. Looking very nice.

I'll have to defer to someone else on velvet qualities. I got nothing on that one. But I did see this thread pop up the other day. I haven't read it, but it may have some good info...

VELVET CLOTH for screen side wall and front ceiling

No Velvet is but subwoffer does not care about that if you are putting them back there.

Ok. I have everything up and running. I'm finding out that my Onkyo 705 might be a little under powered to run my M&K 750 THX LCR and 550THX surrounds, also the bass from the v1250 is inadequate. I really want to wait to upgrade to a new Dolby Atmos compatible receiver but I hate buying new tech before the bugs are worked out of the first generation. So what should I do? I'm leaning towards getting a 2-3 channel amp to provide the needed power to my lcr. Ideas?

Wraunch, love the room. Carpet is really nice, and of course you have excellent taste in speakers. I would look at getting multiple subs. I'm an SVS fan myself. I recommend sealed but some people love ported. I tried it and I just like sealed much better. A 3 channel amp from Emotiva would be great. Also try looking on Audiogon for a good deal on a nice 5 channel or 7 channel amp for your surrounds if you can swing it. If not, then the 3 channel from Emotiva will make a noticeable difference. Also, I would look at buying an SPL meter from Radio Shack if you don't have on already.

Time for an update. We have been enjoying the theater for a month now and it is quite awesome. I have had a few side projects like building a cabinet for my built in football display case and I recently finished my DIY most posters that will double as acoustic panels once I get some OC703.

Just dropping in to say well done on a great build.

We did our conversion of a basement room into a HT last year which included 8 DIY acoustic posters like yours. Those get more comments than anything else when friends come over.

Your KISS approach to the false wall and AT screen are exactly what I have in mind for our next upgrade (right now just projecting onto painted drywall). The spandex and surrounding velcro panels really look sharp and clean, and I bet the immersion factor is nice.

Rock on.

Thanks Red! I am going tomorrow to pick up my wet bar cabinets then all that will be left is to install them and the granite and build my bar seating behind the riser. The posters make a huge difference in the feel of the room. I haven't put OC703 behind any of them yet but I think I will get a pack of it to start experimenting with which ones need it or not. I also need to get some blank cover plate for my MA rack at some point.

Once I'm done I plan on detailing pics with prices paid for various things to really blow everyone's mind. This has been a 2 yr project but I have gotten some steals by taking my time.
