Thanks, David! The room gets a fair amount of use. I schedule a movie night almost every week, unless I have other plans like concert tickets. Lately, I've also done a series of nights featuring concert films, which are especially enjoyable given how much effort went into the room's acoustic performance. What I haven't done as much of as I thought I would do is just sitting in the room and doing 2-channel listening. Honestly, I'm not really sure why. The 2-channel performance is fantastic, and when I have started listening, it has usually stretched on for hours.
There's not much I would do differently, but there are a few things.
I regret that we didn't manage to built a ventilation fan into the kitchenette to exhaust the small amount of smoke that the popcorn machine puts out. I end up shutting the door into the theater and opening the door into the garage while I'm popping, just to keep any smoke from getting into the room. This is my #1
desired improvement (well, that and fixing the ice maker in the little fridge...).
I have been frustrated by the amount of time that it takes for the projector to re-sync when going from the Kaleidescape player's 1080p/60 onscreen display to 1080p/24 movies. I initially planned to just run the projector at 1080p/60 all the time, but I found the judder from the 3:2 pulldown offensive, and the Sony's inverse telecine is very good, but not perfect. I've had some success improving the re-sync by using Lumagen's HDMI Extender, which leads me to think that part of the problem is the cable length to the projector. I'm thinking of trying a fiber optic HDMI cable to see if that could improve things even more.
The custom side masking system is still unfinished. This is a classic case of getting the theater into a condition where it was good enough to really enjoy movies, and losing all motivation to continue working. I do plan to work on this during the Christmas break this year, and I really want to wrap it up so we can put the access covers in place and truly call the room finished.
The room was designed before Dolby Atmos, so there are no ceiling speakers, and since the ceiling is treated, we can't bounce sound off of the ceiling. Honestly, I'm not sure that I care at this point.
Finally, a top of mind regret this week is that I wish we had designed the stretched fabric panels so that they were removable wherever there was a speaker behind them. One of my rear surrounds has developed a resonant buzz. I can gently press on the speaker's bezel through the stretched fabric, and the problem goes away, so I'm confident that it's an easy fix. Easy, except that the fabric will have to be taken down and then re-stretched there, which is a pain.
On the flip side, there are some things that really worked out well.
The Lutron light-blocking shades turned out better than I ever could have hoped. They are 100% effective. So much so that you absolutely cannot see anything in the room even at high noon when the shades are down. This has made it possible to enjoy afternoon movies and summer evening movies without any compromise in image quality.
I am also really glad that I had the idea to drop additional Lutron shades in front of the book shelves on either side of the screen. Once or twice, the RadioRA signal has not triggered one of those shades, and you really do see some reflection from the spines of the books. With the shades deployed normally, there's nothing to distract from the image on the screen.
The Ekornes seating is outstandingly comfortable. I am extremely pleased with it. I still need to find some small tables that we can use for drinks and popcorn, since they don't have cup holders, but otherwise they are superb.
The Sony projector is very very good. I don't think there's a better choice for the room. As much as I love the DLP look, the extreme quiet of the Sony is crucial to the success of the room, and no DLP on the market today is that quiet. Plus, of course, the Sony does a stellar job of converting 1080p to 4K, and the total lack of visible pixel structure on the screen is fantastic. If it didn't have the bright line across the grey field from the lamp power supply, it would be perfect. As it is, I do see that occasionally and it's annoying.
The Screen Research screen has also performed splendidly. The sound of the center channel through the woven screen is outstanding, and the Lutron motor in the masking curtain is accurate, quiet and fast. I do notice a small amount of moiré on that masking curtain if the scene is very dark. If I could replace the top masking curtain with a non-AT black velvet, I would probably do so. It doesn't come anywhere near the speakers so the AT material is not needed there.
The idea of using the Lumagen's image shift to move 2.35 content to the bottom of the screen so that I just had to mask the top has proven to work very bit as well as I had hoped. I'm delighted by the results there, and with a little effort I was able to get all the programming sorted out to automate it based on the aspect ratio triggers from the Kaleidescape player. With that super accurate Lutron motor in the masking curtain, the screen masking is absolutely dead on.
We put an obscene amount of time, effort and worry into making the HVAC systems in the room quiet. And it was worth every bit of it. The HVAC is absolutely, utterly silent. You can sit in the room with everything else off, and still not hear it at all. In fact, the room achieves an NC-14 noise rating with the projector and HVAC on. That's pretty spectacular. With projector and HVAC off, we manage an NC-8.
I'm so happy that we decided to do the radial pattern in the wood floor on the stage. It delights me every time I walk into the room, and it also draws rave compliments from visitors.
And, last but far from least, the overall acoustic design from Keith Yates has been very very successful. I get nothing but compliments on the sound of the room, especially when I give visitors a demo of music seated in the prime seat which is right at the sweet spot for the left and right speakers.
