If you are at all concerned about sound quality/proper surround sound that actually works well, you will re-consider the aesthetics of the room and swap that plan for a more standard speaker layout.
I suggest using the straight forward examples at the Dolby site as a reference point for your HT space. The front & center speakers should be directed toward the listener, since that's how your ears are situated on your head The sound tends to be extremely muddy when coming from above in all directions.
Watch the embedded videos to see the illustrations. This will show you how the sound needs to be directed in order to achieve the desired effect
We are somewhat new to the home theater system design and setup, so I wanted to solicit some help. Based on the outstanding review by CNET, we are purchasing a Sony STR-DN840 for our home theater av receiver. I need help with the speaker selections. I want to put the surround speakers in the ceiling. I am looking for recommendations for in-celing speakers and front speaker. I would like to keep the price moderate but still have good sound quality.
I did look at the HTD in-ceiling speakers online but do not know anything about them.
