I have 2 Sonos One SL’s, a sub and a Sonos Arc in a 550 sq ft room with a kitchen/dining room adjacent to it. The tv room portion has a vaulted ceiling that is 11 feet tall. Can I accomplish Dolby Atmos with this set up?  Do I need Era 300 to help achieve it?

You can play Dolby Atmos audio, but both the Arc and Era 300s rely on upward firing drivers to play the height channel effects. If you have vaulted ceilings, the upward firing drivers don’t have a good ceiling to reflect sound off of. Ideally you need ceilings that are 8-9 ft. tall and FLAT.
