I’m currently building a house and decided since my wife and I have a collection of over 1,000 movies to build a stand alone cinema. It isn’t a separate room or anything but we already have an Optoma 4K short throw laser projector picked out with an Elite Screens Cinegray screen. My limitation is that I need the speakers to all be in ceiling except the front channels and was wondering if anyone has had any experience. I picked out a Marantz 11 channel receiver and was hoping to go with Monoprice speakers. I am looking at a pair of 3 way Amber wall speakers and an Amber center channel for on the wall on each side and under the screen. I was looking at getting the in wall Alpha subwoofers and Alpha ceiling speakers. I’m curious if I can get the 15 degree Alpha series to use as the surrounds and 4-6.5 inch straight ceiling speakers for the Atmos. I considered going with Amber speakers in the ceiling but figured it would be better with the Alpha having the dome tweeters and not the ribbon tweeters. I know ribbon tweeters are more directional and dome tweeters will disperse the sound better. I’m not even sure a 7.2.4 all in ceiling is all possible but would love it if it was. And the ceilings are just under 8 feet.
