To group the Smart Soundbar 600 with other Bose speakers, use the Bose app's Group button; Bose says all systems must be updated, each must be controllable in the app from the same account, and a reset plus an app reinstall fixes stubborn cases. Saved Groups arrived with firmware 10.0.26 and appear in Spotify too. If one grouped speaker is silent, Bose points to Wi-Fi strength, band choice, extenders, WMM and channel settings.

Before you touch a setting
Record this first — changing settings destroys the evidence
- Which speaker is silent or late
- Firmware versions of each speaker in the group
- Whether an extender is in use
Try in this order
0 of 5 completedUpdate everything
ReversibleCheck each speaker's firmware in the Bose app and update. Bose lists mismatched firmware as the first cause when a group cannot be created.
Confirm each speaker works alone
ReversibleOpen each speaker in the app and adjust volume. If one is unavailable, add it to your account again.
Create the group
ReversibleTap Group in the app, choose + Add All or pick speakers under Smart Speakers, then tap the X when finished.
Improve Wi-Fi
ReversibleCheck Wi-Fi Strength in Technical Info, switch bands, choose a fixed channel and avoid extenders as Bose advises.
Reset and reinstall
ReversiblePower-reset the affected speaker for 30 seconds, restart the phone, and reinstall the Bose app if the group still will not form.
Model-specific
What is true of this model and not of its siblings
- Group limits
- SimpleSync groups the soundbar with one Bluetooth device only; grouping several Bose speakers is done in the Bose app, and Saved Groups arrived with firmware 10.0.26.
Stop boundary
When this stops being a self-service repair
- !If a speaker cannot join any group after a reset and app reinstall, request service
- !If Wi-Fi Strength stays worse than -80 dBm, move the router or speaker first

Exact questions
Common questions
What are Saved Groups?+
Groups stored in the Bose app for repeated use.
Do Saved Groups appear in Spotify?+
Yes, Saved Groups appear in Spotify from firmware 10.0.26 onward.
How many Bluetooth devices can join?+
Only one Bluetooth device can join at a time, through SimpleSync.
Where is Group in the app?+
On the product control screen or My Bose.
Can Alexa group Bose speakers?+
No, voice cannot group Bose speakers.
What fixes a silent grouped speaker?+
Reset it, check Wi-Fi and reopen the app.
What Wi-Fi band works best?+
Whichever band is less crowded in your home; test both.
Does volume adjust per speaker?+
Yes, plus a Group Volume slider.
Is it worth grouping speakers on different Wi-Fi bands?+
It works, but a mixed-band group is more likely to drift out of sync than one where every speaker sits on the same band, so if echo or lag shows up in a group, moving every member to one band is worth trying before assuming a speaker is faulty.
