Hi @monoaural_
I don’t work for Sonos but you’ll see those numbers vary on new equipment such as a Beam. I believe it’s more internal to Sonos .
If the box says Gen 2 then I’d say that’s what it is...a Gen 2. I’ve seen no announcements indicating that a significant change was made to the Sonos One (Gen2) that would cause consumer concern. Then again I’m not privy to Sonos internal workings.
Often times companies change vendors for a component and they will designate a reference number to identify which product contains the component manufactured by Vendor A versus Vendor B.
However, since you say the booklet design is different...then that could be the reason for the difference in the Series ID. They’re identifying which product has the design change in packaged literature.
I hope this helps. If not call Sonos to see if you can get a more definitive answer.
Cheers!
If you look at the serial number the first four digits are the year and month of manufacture, YYMM.
Don’t think it matters but it might answer why they are different. I’d ask though.
