- Does this bundle give true surround sound?
- Yes. The Arc handles the front and height channels, and the two Era 100 speakers act as rear surrounds, so you get 5.1.2 with Dolby Atmos.
- Do I need an HDMI eARC TV?
- The Arc connects over HDMI eARC for Dolby Atmos. Older TVs can use the optical adapter, but you lose some Atmos and CEC control features.
- Can I use the Era 100 speakers elsewhere?
- Yes. They work as standalone Sonos speakers or stereo pairs, and you can reassign them in the app if you stop using them as surrounds.
- Is the Sub 4 required?
- No. The Arc and Era 100s run without it, but the sub adds the low end the bar alone cannot produce, especially for movies.
- Does it support Bluetooth?
- Yes, the Arc and Era 100 support Bluetooth in addition to Wi-Fi streaming, so you can play from a phone directly.
- Will it work with a projector or older receiver?
- It works with any TV or projector that outputs audio over HDMI ARC/eARC or optical. It has no HDMI passthrough, so external sources connect to the TV, not the bar.
- Where is the Sonos Arc Premium Smart Soundbar with Sub 4 Subwoofer 2x Era 100 Speaker cheapest?
- At Adorama, for $2,236.00, as of our latest check.
