Thank You @dekay . This is helpful. I found out that they also sell OC 703. So I will check out the table and decide.

Gentlemen, Thank You for the various suggestions. I will start looking into getting the Owens Corning 703. Thinking of 2' X 2' X 2".
@noromance the idea of symmetry is nice. But like I said, the RIGHT side has absolutely no issue. So I don't want to touch something that is working fine.😀
@mijostyn currently I have no plans to change the speakers.
@hild45, I had taken a look at ATS site yesterday. And I see that you have their OC 703 panel. What did you use on the one panel that is flush mounted on the ceiling?

@noromance , @asctim, Thanks.
The panels on the back are a bit thick (GIK 244) and mounting would be a pain. Any suggestion on where to get a square 2' X 2' X 2" thick panel? How do you mount such a panel on the ceiling? What about handling this stuff? Current GIK panels are all finished products, so handling is not an issue.

@bigby Thanks. I did take a look at you room. You have amazing room treatments and that room looks pretty nice and big. Those ceiling treatments probably do wonders. But I am looking at something simpler. I also use GIK throughout my room. But I don't think they would sell a single panel. Nevertheless, let me reach out to them with my requirements.

On the ATS Acoustics site, I found the
"ATS Acoustic Ceiling Panel 24 x 24 x 2" ceiling panel. But this is not OC 703. The specs indicate "Knauf Board with ECOSE® Technology". Anybody familiar with this? What is the difference compared to OC 703?

Very good point indeed. But I don't drive with window rolled down. The vocals are dead center. The songs don't appear left heavy. I think there is some smearing going on on the left side. The images appear pretty close to the left speaker. I want them coming off at least 2 feet to the left and 4-5 feet behind the left speaker, just like how the right speaker images. The images in the middle appear close to the wall behind which is almost 6 feet away. |
@onhwy61 Not test CDs, but regular CDs. For example:
1. Five Feet High and Rising - Johnny Cash
2. The House Song - Peter Paul and Mary
3. You never Give Me Money - Beatles
4. By Myself - Rosemary Clooney
4. Sweet Lullaby - Deep Forest
On the Deep Forest sounds seem off the panel at the first reflection point on BOTH sides. These are some (few examples) of the songs that make you sit up and gawk at the sound stage. Honestly that is ear candy to me and it thrills me up to listen to more music. But that is what I am looking for in other songs.
Newer recordings seem better in this regards.
But somehow (maybe I a hallucinating) the LEFT side the sound seems to stick closer to the speakers and not as much outside as the RIGHT side. Maybe I am being finicky - but I think I should at least give it a try.
Thank You everyone for the excellent feedback and sharing your experiences.
I have got responses from GIK and ATS. Will take it up further. Really appreciate it.

One interesting mounting I found on ATS site was the Rotofast mounting system. This really can get the panels flush against the ceiling. I am not sure if I have studs in that soffit, as I understand that it was created to hide the iron beam (this room is in the basement). Wonder if the Rotofast will work with just the dry wall mount.
|
@williewonka ,I looked at your system, but could not find any pics.I already have GIK monster traps and 244s on the wall behind me.Adding vinyl (in my specific case) might not be ideal.

I have placed an order for a 2"X24"X24" 242 Panel from GIK. Now looking for the best hardware to get this mounted flush to the ceiling.
|
@jdub39,I had not heard that before. I was thinking the ceiling is already low on that part and hence keep the panel as close to the ceiling. Any specific reason why to keep it at the same distance as the thickness of the panel? Will be interested to learn more.

As the OP, I wanted to get back on the solution that I put in place. And I still continue to learn more about acoustics.So I went with the GIK 242 2’ X 2’ panel that I mounted, flush with the ceiling. I used a "corner bracket" to do this. My initial position caused minor improvement. The music from the left speaker now were much more cleaner. So I asked my son to hold the mirror against the ceiling panel and I found that the mirror image of the tweeter was off by a couple of inches. Hence I moved the panel about 4-5 inches, but now part of the panel was not under the soffit. And this is where the music transformed and now the images were coming from the left side of the left speaker just as the right side images. I have the new panel pic on my system page so you can see how I mounted it.
And at this point it stuck me as to why, when I had my absorption panels on the 2nd reflection point a couple of years ago, the music lost all dynamism, to the point that I had to move the panels to the back wall. So the soffit was causing "part" of the sound waves to bounce off the sides of the soffit and then hitting the second panel. So most of the music was getting absorbed and that was causing a "blank" at my listening position. With the new panel in place, the sound now hits the panel and appropriately travels at the listening position. I am glad that it was a learning experience, and think that there is a lot that can be done with proper room treatment. But there is no end to that. I have achieved what I was looking for and it is amazing to hear the same music which seems so much more coherent and engaging.
Thank You to all who responded to my post 🙏🏼
