A:Answer I agree and disagree. To get excellent Dolby Atmos surround sound, you really need ceiling mounted speakers, or mount the Onkyo speakers on the wall near the ceiling above your front speakers. When you place these on top of your front speakers and fire them towards the ceiling, you do get Dolby Atmos sound, but it is not as good as ceiling mounted speakers. The size of these speakers are perfect for what they are designed for, however, the larger the room you are listening in, the larger your speakers should be.
