The second-generation Beam adds HDMI eARC and virtual Dolby Atmos to Sonos’s compact soundbar in a package that fits under any 40-inch or larger TV. The upgrade from ARC to eARC means it can now receive lossless Dolby TrueHD audio from Blu-ray players and gaming consoles routed through the TV. At 651 mm wide, it’s roughly half the size of the Arc, yet still handles 5.0 virtual surround with five Class-D amplifiers. An included optical-to-HDMI adapter covers older TVs without an ARC port.
