Sonos Era 300
Era 300 uses six optimally positioned drivers to project sound forward, to the sides, and overhead. Its upward-firing tweeter reflects sound off the ceiling for height with Dolby Atmos content, creating an expansive listening experience from a single speaker.
Sonos Era 300
Era 300 is built around immersive listening. Six optimally positioned drivers send sound forward, to the sides and overhead, creating a spacious presentation from a single speaker and unlocking Dolby Atmos Music when the content supports it.


Acoustic architecture
Four tweeters handle the high frequencies, including an upward-firing driver in a directional horn that uses the ceiling to create height with Dolby Atmos content. Side-firing tweeters expand the presentation beyond the cabinet.
Two woofers are angled left and right for balanced low frequencies, while six Class-D digital amplifiers are individually tuned to the acoustic architecture.

Dolby Atmos Music
Traditional stereo establishes width between left and right. Era 300 adds spatial height and lateral projection, allowing supported Dolby Atmos Music to place elements around and above the listening position.
The result is not simply a louder speaker. It is a presentation that feels larger than the cabinet itself, with more space for vocals, instruments and ambience to occupy the room.

Play it your way
Use WiFi for the full Sonos experience, whole-home playback and Apple AirPlay 2. Bluetooth 5.3 gives phones, tablets and guest devices a direct way to play.
USB-C line-in adds wired-source flexibility with the Sonos Line-In Adapter. Ethernet is also available with the Sonos Combo Adapter.

Room intelligence & control
Trueplay measures how sound reflects around the room and optimises Era 300 for its actual position. Control playback from the Sonos app, top touch controls or supported voice services.
Compatible iOS and Android devices can be used to tune Era 300 for the room. Bass, treble and loudness remain adjustable in the Sonos app.
Use Sonos Voice Control or Amazon Alexa where supported. A hardware switch on the rear disconnects power to the microphone hardware when you want the microphones physically off.

One speaker. Several roles.
Era 300 works as a complete spatial-audio speaker on its own, and its role can expand as the room and system grow.
Placement matters
Era 300's side- and upward-firing acoustic design benefits from open placement rather than tight cabinetry. Give it a stable surface, space around the sides and a clear path above.

Sonos Era 300
Start with one Era 300 for spatial music. Add a second for true stereo separation, or use a matched pair as premium surrounds in a compatible Sonos home-theatre system.
