True that the Atmos speakers need to be ABOVE your head and not sitting on a speaker shooting up in the air.
Not everyone can or will implement Atmos speakers just like not everyone will implement separates systems.
Are separates systems (Preamps, Amps, Integrated Amps) overall failure since most people don't "Implement" them?
It's a niche market just like Atmos/DTSX and 4K UHD Blu-Ray, which most people don't and won't "implement".
