Without powering it up. Unit it disconnected from my system, so all I have is the serial number. The Beam itself does not say on the unit. Purchased new in October of ‘19. I’m fairly certain it’s a Gen 2.

 

» I’ve powered it up. Still nothing that says G1 or G2.Bottom of unit says “Model S14”. Runs Sonos OS S2. Hardware version 1.23.1.10-1.9. Series ID: A100. Serial: 48-A6-B8-******

 

Moderator Note: Hiding Serial number. Modified in accordance with the Community Code of Conduct.

The very first part of the serial number is the date of manufacture. Beam 2 was released in fall of 2021.

The easiest way to tell the difference is the Beam Gen 1 has a soft fabric grill. The Gen 2 has a hard polycarbonate plastic grill.
