- Do I need a Sonos Sub with this set?
- No, the set works as a 5.0.2 system. Bass is modest, so a Sub is the usual upgrade if you want rumble.
- How do the Era 100s connect as surrounds?
- They pair over Wi-Fi through the Sonos app and each needs a power outlet. No speaker cable runs to the Arc.
- Does the Arc support Dolby Atmos?
- Yes. The Arc decodes Dolby Atmos and uses upward-firing drivers for height effects.
- Can the Era 100s be used without the Arc?
- Yes. They work as standalone speakers or as a stereo pair, and can be regrouped in the app.
- Which TVs work with the Arc?
- The Arc connects over HDMI eARC. A TV with eARC passes Atmos; older TVs may need an optical adapter and lose Atmos.
- Is a newer Sonos soundbar a better match?
- The Arc remains Sonos's flagship bar with Atmos and 11 drivers. Newer bars are smaller but give up some width and height drivers.
- Where is the Sonos Surround Package with Arc + Era 100 cheapest?
- At Sonos, for $1,457.00, as of our latest check.
