Side-by-Side Comparison

	Devialet Dione	KEF XIO
Channel layout Counts speaker channels the bar actually has. More ear-level and height channels means a wider, taller sound field.	5.1.2	5.1.2
Height channels Drivers aimed at the ceiling, which is what makes Dolby Atmos sound overhead rather than just wide.	2	2
Dolby Atmos	Yes	Yes
DTS:X	No	Yes
HDMI to the TV eARC carries lossless Dolby TrueHD and Atmos from the TV; plain ARC compresses them.	eARC	eARC
HDMI inputs A spare HDMI port for a games console or disc player.	0	0
Subwoofer Included beats optional beats none: a separate subwoofer is where deep bass comes from.	Built-in	Optional
