- Is the Arc Ultra a big upgrade over the original Arc?
- Yes. The Arc Ultra moves to 14 drivers and 9.1.4 channels and adds Sound Motion woofer technology, giving more bass and a wider soundstage than the original Arc.
- Do I need the Sub 4 with the Arc Ultra?
- No. The bar produces solid bass on its own. The Sub 4 mainly adds deeper, more controlled low end for large rooms and action-heavy movies.
- Does it support Dolby Atmos?
- Yes. The Arc Ultra decodes Dolby Atmos and uses upward-firing drivers for height effects, and it also handles Dolby Digital and stereo content.
- Can I add rear speakers?
- Yes. You can pair Sonos Era 300 or Era 100 speakers as surrounds for a fuller 7.1.4 or similar setup, though they are sold separately.
- What connections does it have?
- It has one HDMI eARC port, Wi-Fi, Ethernet and Bluetooth. There is no HDMI passthrough, so other devices connect to the TV rather than the bar.
- Does it work with Alexa and other voice assistants?
- Amazon Alexa is built in for voice control. Sonos also supports other assistants through the app and its own voice control options.
