The role of sound at home has fundamentally changed.
What was once background noise has become central to how people live, relax, and connect. Music plays throughout the day, podcasts accompany daily routines, and films and shows are no longer just watched, they are experienced. The home has evolved into a multi-functional space, and sound now shapes each of those moments.
This shift is being driven by how people consume audio today. More than 700 million people now subscribe to music streaming services globally, and platforms like Apple Music have introduced spatial audio formats such as Dolby Atmos into everyday listening. What was once reserved for cinemas or specialist setups is now accessible at home, raising expectations for how sound should perform.
Sonos has been at the center of this evolution for over two decades, building products designed not just to sound better, but to fit seamlessly into how people live. Arc Ultra, Sub 4, and Era 300 represent that progression. Individually, each one delivers a distinct experience. Together, they form a system that redefines what listening at home can be.
Arc Ultra: The Foundation of Home Entertainment
At the center of the modern home is the living room, and Arc Ultra is built to elevate it.
With 14 custom-built drivers and a 9.1.4 Dolby Atmos configuration, Arc Ultra creates a fully immersive soundstage that places audio around and above the listener. Dialogue remains clear through AI-powered Speech Enhancement, while its refined design allows it to integrate seamlessly into the space.
On its own, Arc Ultra transforms TV audio into a cinematic experience. As part of a wider system, it becomes the foundation of a complete home theater setup.
Sub 4: Precision, Power, and Depth
Sub 4 adds the dimension that brings sound to life.
Its dual inward-facing woofers are engineered to eliminate distortion while delivering deep, controlled bass. The result is not just more impact, but greater clarity across the entire system, as other speakers are freed to focus on mid and high frequencies.
Paired with Arc Ultra, Sub 4 enhances everything from films to music. In a broader setup, it adds balance and depth that elevates every listening experience.
Era 300: The Shift to Spatial Listening
As spatial audio becomes more widely available, the way people experience music is changing.
Era 300 is designed specifically for this new format. With six precisely positioned drivers, including an upward-firing channel, it projects sound in multiple directions to create a truly immersive listening experience.
As a standalone speaker, it delivers room-filling sound that surrounds the listener. As part of a system, two Era 300 speakers can be paired with Arc Ultra as rear surrounds, adding height channels and completing a full Dolby Atmos home theater setup without the need for traditional speaker wiring.
What makes these products different is not just their individual performance, but how they work together.
Arc Ultra anchors the experience. Sub 4 adds depth and impact. Era 300 expands sound into a fully spatial environment. Combined, they create a system that adapts to different moments, from watching films to listening to music, without compromise.
The home is no longer a single-use space, and sound is no longer a secondary consideration.
It is a core part of how people experience their environment, and increasingly, a defining element of modern living.
