Hi, I already have a Sonos Beam Gen 2 and two Era 100 speakers. I'm thinking about buying a Sonos Sub Gen 3. The requirements say that you need at least one non-portable product with a built-in amplifier, e.g. Arc or Era 300. Can you tell me whether Will the Sub Gen 3 perform 100% of its capabilities without any problems with this configuration? Is Arc or Era 300 necessary for it?

Of course that will work perfectly. The Beam2 as the home theater master device is ready for the Sonos sub and a pair of rearspeakers to set up a surround system.
