- Is the bundle cheaper than buying the three pieces separately?
- Usually not. The Arc Ultra, Sub and a pair of Era 300s regularly go on sale individually, and the combined sale price often lands below this $2,808.20 bundle at Amazon as of November 3, 2026. Compare per-piece prices before ordering.
- Do I need the Sub with the Arc Ultra?
- No. The Arc Ultra has built-in woofers and works alone, but the Sub adds the deep low end that makes action scenes feel full. If you live in an apartment, the bar alone may be enough.
- Will the Era 300s work as rear speakers?
- Yes. In the Sonos app you add them as surrounds, and their side and up-firing drivers are used for Atmos height and rear effects. They also play as normal stereo speakers when not in surround mode.
- What is in the box?
- You get the Arc Ultra soundbar, one Sub subwoofer, two Era 300 speakers, power cables for each, and the bar's HDMI cable. Stands and wall mounts for the Era 300s are sold separately.
- Does it support Bluetooth?
- The Arc Ultra supports Bluetooth streaming. The Sub and Era 300 stream over Wi-Fi through the Sonos app, so Bluetooth playback comes out of the bar and the rest of the system follows it.
- When is it cheapest?
- Sonos discounts around Black Friday and in spring sales, and per-piece sales often beat bundle pricing. Watch the price history for each component rather than the bundle alone.
