CEDIA Expo 2014: KEF

For most of the high-end speaker manufacturers, they are content to let people use in-ceiling speakers for Dolby Atmos. If you assume most people doing Dolby Atmos will have a dedicated theater, then this does make some sense. However, there are people with dedicated theaters that do not want to install in-ceiling speakers.
