Acoustic panels on ceiling

In this situation I would contact GIK directly and e-mail them pictures of your room as it is currently  set up. They are very helpful in helping their customers utilize their products.

I did. They said “put them where the first Reflection points on ceiling are”. I tried the mirror trick (hard on ceiling), and could not see anything 

thyname, mind me asking what is the mirror trick?

@jetter see this:

Jetter it is a bit difficult on ceilings but you have to find the early reflection point. To do that you sit in the listening position and have somebody else hold a mirror against the ceiling and walk slowly between you and each speaker. when you can see the speaker's reflection in the mirror that would be that speakers early reflection point. Then do it for the other speaker and place one panel for each speaker centered on those points. The trick is to find a way for that person to do that. Either a ladder that you have to keep moving or a mirror on a long handle. The mirror has to be flat against the ceiling. The other way to do it is with a laser. You shine the laser on the mirror and when it hits the speaker you have it. Have fun!,
