The Sonos Era 100 SL is on sale for $159 during Prime Day, down from its usual $189 — the lowest price trackers have recorded for it.
The SL variant strips out the microphone array found in the standard Era 100, which means no Alexa or other voice-assistant support. Everything else carries over: stereo driver configuration, Bluetooth connectivity, room-correction technology, and full compatibility with the Sonos multi-room ecosystem. The Era 100 SL differs from the older Sonos One SL in a meaningful way — it uses a stereo driver setup rather than a mono speaker, producing a wider soundstage and better instrument separation. Manual bass and treble controls round out the feature set.
At $159, the case for this speaker is straightforward: you get most of what makes Sonos worth buying — sound quality, ecosystem flexibility, and room correction — without paying for a microphone you may not want. The ability to add speakers incrementally without replacing existing hardware is a genuine advantage over rivals that push you toward proprietary closed systems.
The caveats are real: no Dolby Atmos support (that's the Era 300's territory), limited headroom in large rooms, and some composure loss at maximum volume. The sale runs through June 26.
