Okay I have my qs8 temporarily place on the side walls about 5 foot off the floor = 2 1/2 feet above ear level when sitting down

They are 3 foot from the back wall and I have 13 foot ceiling at the point on the wall in where the qs8 is mounted (as that is where my sloped cathedral ceiling hits its peak)

What is happening is I'm getting a phantom rear center channel from the speakers but the sound seems to be coming from above, almost like I have a monopole speaker place on the back wall like 8 foot up in the air pointed down at my listening postion...

I'm gonna experiment with moving them up higher on the walls, but I was wondering if the phantom rear center should sound more directly behind me versus more up above me and to the rear ?

Also if I raise the speakers does that mean the phantom rear center will seem to elevate higher up into the room as they qs8's are raised ?

Also if I lower them , does it lower the phantom rear center channel ?

would appreciate some feedback,
Halo
