Sonos Premium Home Theater Completion Set (Sub 4 + 2x Era 100) Q&A:

What do I need to use this set for surround sound with my TV?

You’ll need a compatible Sonos soundbar to act as the front of your home theater. Add Sub 4 and set the two Era 100 speakers as rear surrounds in the Sonos app.

Can the Era 100 speakers be used as rear surrounds and also for music?

Yes. When paired as surrounds, they create immersive rear-channel effects for TV and movies, and they can also help deliver a fuller, more spacious soundstage for music within your Sonos system.

Is everything wireless?

Audio connects wirelessly over WiFi within your Sonos system. Each speaker and the subwoofer still need to be plugged into power.

Where should I place the Sub 4 for best bass?

Sub 4 is designed for placement flexibility and can sit upright or lay flat. Trueplay tuning helps optimize bass performance for your room—even when placed near a wall or under furniture.

Does Era 100 support Bluetooth and line-in?

Yes. Era 100 supports Bluetooth 5.3 for device streaming. For line-in, connect a source using a Sonos Line-In Adapter (sold separately) via USB-C.

Can I hardwire either product with Ethernet?

Sub 4 includes a 10/100 Ethernet port. Era 100 can be connected to Ethernet using the Sonos Combo Adapter (sold separately).

What’s included in the box?

Each product includes the unit, a 6 ft (2 m) power cable, and quickstart plus legal/warranty documentation (two Era 100 boxes and one Sub 4 box).

Can I add a second subwoofer later?

Depending on your Sonos setup and compatibility, Sonos systems can support dual subwoofers for even deeper bass impact. Check your specific configuration and compatibility guidance in the Sonos app.
