IDK, some say that they like the rubber matting to reduce vibration, but I've never done that. I went the "fill the stage with sand" route, and it's worked very well for me. I don't hear any vibration whatsoever coming from the stage.

IIRC from talking to @BrolicBeast they are primarily used to focus sound axis, pressure, and DBs to a specific direction. This leads to a net gain in SPL and raw DBs at a given location. He's much smarter at them, and can clarify/correct me tho.

Yeah, baffle walls can help to reinforce the sound, especially in the midbass range (I think), but it learned to my dismay that they're really supposed to be quite dense and rigid... Like double DW & GG sandwich dense and rigid.

I know some of the guys with big QSC speakers said the baffle wall really made them come alive, but it isn't as simple a job as I had originally thought.

Regarding a baffle wall for the titans I do not think it is necessary but I could be wrong. I heard but I am hope I Matt @mtg90 could confirm that the crossovers for the titans are design so a baffle wall is not needed. As I said I could be completely off track here.

As for the QSCs there are designed to be in a baffle wall

4/11/19 - hang time!

This afternoon was an adventure! I got the z-clips installed on the back side of the screen & screen wall, then realized after placing it on the wall that there was a noticeable bend in the middle. So down went the screen, and all zip ties pulling the screen from the bottom. Took out the bracing, and installed longer, more rigid pieces, which helped keep the height in the center of the screen.

I think I still notice a very minor bend, but am going to wait and see how the a projected image looks before I make any other big changes to the screen.

There are minor dimples on the bottom edge of the screen, but it’s only noticeable when the spot lights on the top of the screen project down. When direct light is thrown on the screen, it looks like a perfect screen. Overall, I’m happy with how it turned out, I just hope that the minor bend won’t be too noticeable, otherwise I will take the screen down and do the same thing in the quarter sections of the screen.

Aaron, my professional Seymour screen in my last theater had a few dimples only noticeable with down lights also.

Man that looks great. I love it. Perfect size.

It may be the camera but I think I notice the bend also. Either way it looks fantastic.

Ok I’ve done some laser leveling and there is a minor difference between the middle and the edges. But not huge. I’m calculating a 1/16” to 3/32” difference between the middle and edges with my laser level. It’s this spread at the top and bottom, so a total difference of 1/8”.

The question here, is will this be noticeable when the projector throws an image onto it? I guess the one way to test is for me to pull the projector out and see.




MIDDLE



RIGHT



LEFT

I talked some sense into myself. I’m just going to push forward and will circle back to the screen if and when it’s an issue.

Working on velvet frames now.

That's a valid concern, the risk of seeing a 1/32" difference from 10'.

IT'S A TRAP!!!

Sir, please step away from the projector box, and focus once again on the side panels!!

You'll see it as soon as you project a football or basketball game that has a nice, straight-edge graphic along the bottom of the screen. Trust me.

I love my iPhone, but it will never replace my turntable. I've never seen Titanic OR XXXXXXXXX. Alexa is a stripper name.

Most people would be lucky to get their projection aligned to 1/16” at all four corners. That’s what the velvet frames are for.

My hope is this exactly. I hope that the small variances will be covered by the velvet frames.

This is one of the exact use-cases I thought about in my mind. If there is a noticeable defect when Projector time rolls around, I will re-visit and make adjustments.

Frames are half complete! It’s always fun measuring and building panels around imperfect designs and imperfect construction. I had to make the panels imperfect to fit perfectly within their slots!

I don’t know why I waited so long to buy a Kreg jig. These things are awesome.

4/12/19 - completed stage wall

Woohoo, another mile marker passed. There are tiny imperfections all over the wall, but for a weekend warrior, I think I did alright, and I’m happy with the end result. The velvet I used is slightly different from the velvet that came with the screen; it’s not as pure dark as the screen velvet, but I’m venturing to guess it won’t be noticeable when the projector is running.

All of the panels are friction with just one or two Small Velcro spots to ensure a solid hold. The Velcro was much easier to staple than the GOM high beams fabric on the walls, which made the frame wrapping a piece of cake. I hope that the friction fit will hold through bass wobbling scenes from the six UM-18’s - time will tell.

There is no time for rest! I am cleaning the room as we speak and am prepping for step paint.

No way! Most people would consider the guy who still hasn’t finished his theater after three years the loser (me!) rather than a highly productive person such as yourself.

Less than a year and Aaron you have come up with such a beautiful theatre, kudos to you my friend. It is nice to have that freedom to get your goals done in such a short period of time. Can’t wait to hear about your impressions on the first movie you watch
