Hello, 

I’m using BEAM Gen1 connected to a couple One Gen2 surround speakers. 
I would like to add additional 2 ERA100… is it possible?

Not as a single room home theatre setup, no. Beam provides the front 3 channels and the Ones give the rear effects, so that’s your 5.x system. 
If you want a two-speaker stereo setup you could use the Eras and locate them in the “traditional” location relative to your listening position, or use them in another room entirely. 

In any Sonos HT system you can only attach/bond two rear channel left/right surround speakers and either one, or two, Subs (one must be a G3 Sub), or alternatively you can use one Sub Mini.

The front channel left/right speakers are built-into the main Sonos HT products, such as the PlayBar, Arc, Beam etc. so you cannot add speakers to replace those front channels.

You can ‘group’ (not bond) Sonos rooms/speakers together however and this works great for music playback, but note that any rooms/speakers grouped with a Sonos HT for playback of TV audio will have a 75ms audio buffer delay - if the grouped speakers are in the same room you may notice an echo effect across such grouping.

There are tools in the Sonos App however to help address this sync issue - see this link for further information:

Note: the ‘TV Dialog Sync’ feature will of course buffer the TV audio output and that ‘may’ lead to you noticing lip-sync issues with the video display on screen.

Hope that information assists.
