Although Dolby is not a manufacturer of physical speaker products, overhead (or in-ceiling) speakers are fundamental to a home cinema system configured to reproduce the Atmos surround sound format, and so we have created a section of speakers that give good results when used for this application.
In-depth information can be gained from Dolby's website here
You can also read a concise summary on our blog post here
If installing two speakers as Atmos channels then the speakers should be almost directly overhead and in this case any ceiling speaker with a reasonable sound dispersion can be used. However if this cannot be achieved, or if you are installing four Atmos speakers, then speakers with wide dispersion characteristics should be installed and it is these models which are featured here.
