At the bottom of every room page, the room diagram gives you a live picture of the speaker topology in that room. Rather than just showing a name, it renders the actual layout — left and right units for stereo pairs, a subwoofer when one is bonded, and the front and surround satellites around a soundbar. It’s a fast way to confirm you’re looking at the right room and to see how it’s configured before you start adjusting.

​
What the diagram shows

Stereo pair

Two speakers side by side, marked left and right.

Single speaker

One speaker, centred.

Bonded subwoofer

When a Sub (or two) is bonded to the room — soundbar or not — it appears alongside the other speakers.

Soundbar with satellites

The soundbar at the front with a listener figure below it; surrounds behind, and separate front speakers either side of the bar when bonded. A Center label appears only when fronts are bonded and the bar has become the centre channel.
The diagram always shows what is really bonded, read from the Sonos® system. After a configuration change it updates on its own; if it lags, pull down to refresh — Sonos® can take up to a minute to propagate topology changes.

​
Press and hold to configure

The diagram carries a pulsing “Hold to configure” hint whether the bar is bare or fully built out. Press and hold to open Home Theater Setup, where you assign fronts, surrounds and up to two Subs. See Speaker Setup.
Stereo pairing and home theater bonding both happen inside Somos InControl — you don’t need the official Sonos® app for either. If a configuration doesn’t complete, the app restores your previous setup automatically.
