I've wanted to experience Dolby Atmos for a long time. I'm beginning to believe that it will never work due to my room size. The room area is 52' by 38' with the main living area having a 13' cathedral ceiling. The room opens up to the dining area, the kitchen, and the foyer into the hallway. I will post pictures to help visualize the layout. My equipment is a Denon avr x 4400H receiver, 2 DefTek Bp 9060 front speakers, 2 SVS prime bookshelf for rear surrounds and 4 SVS prime elevation speakers for Dolby Atmos. I've run the Denon audyssey setup several times. I initially placed the SVS elevation speakers high on the wall and aimed them towards our seating area. Didn't hear any Atmos effects. I then placed them on top of the front and rear speakers aimed at the ceiling. The distance to the ceiling is @ 7 feet. Again I don't hear any overhead Atmos effects. I'm using a Panasonic DP-UB820 for UHD playback. I have not attempted to mount the speakers directly to the ceiling, my wife will only tolerate so much. I've compute that I have roughly 16,000 cubic feet of space. Even playing DTS HD movie soundtracks at a loud volume doesn't give me anywhere near the experience I was hoping for. My question is, should I just forget about Dolby Atmos and sell the SVS Prime elevation speakers and perhaps buy a more powerful receiver that would simulate the dolby and auro 3d experience since I can't really enjoy it with my current setup. Any suggestions would be greatly appreciated. Thank you all in advance for any help you can offer.
