Open beam ceiling: how to choose height / ceiling Atmos speakers?
I'm updating to a 5.1.4 Atmos system and need some advice on how to mount height/ceiling speakers in our family's viewing area which has an open beam ceiling. The rafters are 9" deep. The ceiling speakers would complement a T305 Home Theatre Speaker System (basically T301 speakers).
I've seen plenty of forum posts on recommended *speakers, but few ideas on speakers that could be mounted *on* the ceiling or mounted on the side of the rafters facing downwards. I was originally thinking mounting four Q100 bookshelf speakers facing downward on the side of the beams. However, doing so would require drilling into the side of the speakers, which KEF said would void the warranty. Also, the Q100 speakers are also a bit too deep, and would extend a couple of inches below the bottom of the beam. How well would bookshelf speakers would do as height speakers? I've also read about Prime Elevation speakers that could be mounted on the beams, or perhaps on the sides of the viewing area facing the center of the area. However, these wouldn't be facing perfectly downward, but at an angle. Would that still be optimal for atmos? Or would I want something facing perfectly down? Or would it be better for me to choose an in-ceiling speaker and insert it in some sort of speaker box, and bolt the box to the rafters? There are small subwoofer
