I had a Polk Surround Bar on the shelf below my TV which was lower than ear level. I purchased a Center Stage bracket and moved the bar on top of my TV and angled it slightly down, it made a great difference. The Center Stage brackets are adjustable, you can adjust the angles on them.
So from what I'm getting here, there are totally no advantages to placing a sound bar above the TV in the sound quality wise right?
The Center Stage Bracket is quite useful, but in my situation where my TV is wall mounted, I'd have a cheaper way. I placed a cardboard above the TV, and another right below the cardboard. That cardboard is then supported by the TV wall mount bracket, while the top cardboard is supported by the TV, bottom cardboard and the wall behind the TV. Unfortunately, I'm not able to tilt down the sound bar to my listening area, I'm only able to put it straight, or tilted backwards. I'd prefer tilting it backwards in case the cardboard gives way, and the sound bar might get damaged.
What are your thoughts for tilting it backwards, where the speaker drivers face the ceiling?
