That's the all-in-one solution but it probably wasn't Dolby's first choice. Contrary to what Bose insisted for years and years, reflected sound isn't all that.
I would disagree. I have a Samsung K950 5.1.4 ATMOS soundbar setup and it is full and rich. And with either true ATMOS material, or the Dolby Experience ATMOS app on the Xbox One, it really performs.
