Second generation Sonos Beam packs support for Dolby Atmos and new audio formats

Sonos today (14 September 2021) announced its Sonos Beam (Gen 2) soundbar, updating its mainstay Sonos Beam. While they look similar on the outside, Sonos has given the second-generation update so much more, at just S$799

The Sonos Beam (Gen 2) now comes with 3D Audio through the help of Dolby Atmos support. It’s also compatible with over 100 streaming services to enhance the surround sound effect. DTS Digital Surround Sound compatibility is also on the cards, but Sonos will only add it to the Beam (Gen 2) at a later time.

Besides Dolby Atmos Music, the new Beam also works with Amazon Music’s Ultra High Definition audio (24-bit/48kHz) - at no extra cost to Amazon Music Unlimited users (implemented “later this year”).

The device can also use HDMI eARC for direct-to-television connectivity, making it much simpler to work with your favourite shows and games without routing to another separate source. 

At a hardware level, the soundbar packs a new processor that’s 40% faster than its first-generation version. Sonos Beam (Gen 2) also has a new phased speaker array to steer its audio for a more lifelike experience - two new audio paths (left surround and right surround) now sit next to its centre array.

As an updated device moving away from its original fabric mesh finish, Sonos Beam (Gen 2) also uses a polycarbonate grille, just like its premium counterpart (Sonos Arc).
