The aesthetic upgrade is obvious. As others have commented I love the rock faced screen wall and the staggered panels which blend very nicely.
You made a comment that the acoustics were as good, if not better than your previous theater. Given the 2D diffuser at the first reflection point and the use of hard flooring in the back half of the room I assume that the sound is noticeably different. I think audio recollection is a muddy thing, but do you have any other thoughts on the difference in sound for movies and music?
I see no comment on the sound proofing. Did the use of channel and insulation have any obvious affect?
Your ceiling height was 7.5 feet correct? How long and wide is your theater?
By the way, I liked your observation that it was difficult to tell the difference between projected black and black shadowed by your hand.
That puts the JVC black level into perspective.
I remember how dismayed I was when I brought home my first projector a few years ago (a Panasonic AE 4000 "Ultra Contrast") and was able to perform shadow puppet shows on a projected black screen. I have been running low cost DLP's ever since. Glad to know that when I upgrade to a real projector the shadow puppet show will be a thing of the past.
You bring up a very good point. I haven't really addressed the final acoustics of the room. At first I hadn't commented because I was waiting on a new processor and didn't want to spend time monkeying with the current processor only to have that EQ work be thrown away when I upgrade. However, I am still waiting on the new processor so I went ahead and re-calibrated everything using the current gear. If my audio memory serves me properly, I can tell a good difference between the old room and the new room. Sound isolation has been improved. Not as much as I had hoped, but it is very noticeable difference. I don't hear people walking around upstairs anymore and with the exception of bass, the sound is mostly contained to the room. The sound doesn't decay as quickly as in the old room thanks to the decreased absorption, so I say the room sounds more alive. However, there isn't a reverb or echo, so it doesn't fail the clap test. I was trying to strike an even chord (pun?) with 2-channel music and movie surround sound and for the money I spent, I feel I accomplished it. I could have improved the sound more, but besides material costs my out of pocket expense for the acoustics in this room was $0!!! I'm not saying I have a room that sounds as good as a Rives or another company's room. But only my time was spent researching and not the $1500-$2000 for a entry level design.
Many 2-channel live concert recording give the impression of a large concert hall. The sound stage across the front has really impressed me. Prior to a few weeks ago, I didn't have anything EQ'ed and I didn't have my ceiling clouds installed (no pictures posted yet). The room and speakers gave the impression of listening to a good set of headphones. I couldn't pinpoint the sound coming from the speakers, but I could pin point the sound stage (imaging) either. I set the EQ, set the distances, played with the amount the speakers were toe'd in, installed the ceiling clouds and BOOM. First track I listened to I literally got up from my seat and walked to the center channel because I swore I had left the multi-channel DSP turned on and the center channel was active and playing. I was happy to find that the center channel was not active and only the main fronts were producing sound. The sound stage between the speakers is amazing and with a little more tweaking I was able to gain some sound stage outside of the speakers width. That is good enough for now. Once I get the new processor I hope to obtain the same results and add the depth to the sound stage.
Movie soundtracks have also benefited. I don't recall the movie I was watching the other day, but several times I turned my head because I thought my wife had entered the room behind me and was about to interrupt my movie. I had similar experiences before with louder, and more pronounced surround sounds, but I am beginning to pick up the smaller effects now. Most multi-channel soundtracks make the walls disappear completely and I hear only what the sound engineer wants us to hear in the 'movie environment'.
To answer your question, my room does have 7.5 feet ceiling and is 12.5 feet wide and 19 feet deep. I would like a larger room, but 60% of the time it is only me down in the room, and for that it is plenty big.
