Yes, you can get Dolby Atmos just from a single soundbar. There are many manufacturers offering these products in the market. These soundbars come with a built-in upward-firing speaker that basically reflects the sound off the ceiling to create a sound field. This is what makes the sound feel like it's coming from over the head. However, the Atmos-enabled soundbar might not be enough to replicate the immersion of a complete Dolby Atmos setup that comes with separate speakers. It is still an affordable and space-efficient solution for people who want to experience Atmos technology.
