Need opinions on ceiling reflections

@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.

@milpai - One thing I have tried tried worked very well in a couple of very different rooms is a vinyl blind behind the listening position.

It is fastened at ceiling height an extends down between 15"-18"

You could simply use a piece of vinyl and pin it too the wall behind the listening chair each side of the dropped ceiling section

The best vinyl can be acquired from those companies that make signs - it is about 1mm thick and very flexible.

I used a vinyl blind because I thought the window that was behind my listening position was the issue, but after it was installed I realized it was not the window, but the reflections at the ceiling causing my problems

@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.

@milpai - I don’t know if this will help, but here are details of my current room....
It is much like your own, but with two dropped (sofit) sections and a beam that run cross the room, as opposed to the length of the room as in your case .The room is also "L" shaped, with the longest wall being 42 ft and the area where the audio system resides is 17 ft wide

Both speakers are located 8 ft from the wall, which places them under one of the dropped sections, so there is very little sound behind the speakers and what sound there may be is probably trapped by the dropped section.

In front of the speakers is a beam and then a second dropped ceiling section is located behind the listening position, which I believe is mitigating ceiling level reflections from the wall at the far end behind the listening position.

My speakers are rear ported, but the ports are 2" x 8", so there is very little in the way of pressure waves and the internal bracing is designed to minimize standing waves. Also the room is fully carpeted, so I have no bass related issues either

When I first setup the system in the new room I was amazed that the only "treatments" it required, was to handle side wall reflections, so I believe the dropped sections are acting in a similar manner to the vinyl blind that I had installed in the last room and they prevent/trap ceiling reflections

Initially, I did have a couple of traps in the corners, but even those proved to be unnecessary, so I have removed them also.

Another room where I found the vinyl was particularly helpful was in a friends 12 foot high apartment with hardwood floors, concrete walls and ceilings. Once again the vinyl only had to hang down 18" from the ceiling. The improvements were immediately noticeable.

In a couple of audio stores I frequented, the ceiling are quite high, so they had various traps and dispersion devices hanging close too the ceiling.

I have read corners at the ceiling/wall boundary can be an issue, so installing some sort of crown molding may prove beneficial

Hope that helps - Regards - Steve
