If you have been searching for a wireless home theater system that actually feels like a cinema, the Sonos Ultimate Immersive Set with Arc Ultra is the setup to stop your search at. This isn't just a soundbar, it's a complete Dolby Atmos surround system, pairing the flagship Sonos Arc Ultra soundbar with a Sonos Sub (Gen 4) and two Sonos Era 300 speakers for true wireless rear surround. In this guide, we break down what's inside the box, how it performs, what it costs in India, and why it's one of the most future-proof home theater upgrades available right now at 8mm.in.
What's Included in the Sonos Ultimate Immersive Set?
This bundle is designed to give you a complete 9.1.4-channel Dolby Atmos experience straight out of the box, with no guesswork about which speakers to pair. Here's exactly what you get:
•  Sonos Arc Ultra Soundbar x 1 — the flagship front/center/height channel with 11 high-performance drivers
•  Sonos Sub (Gen 4) x 1 — dedicated wireless subwoofer for deep, room-filling bass
•  Sonos Era 300 x 2 — wireless surround speakers with spatial audio drivers for true rear Atmos channels
Key Features That Make This System Special
Phased Array — A Realistic Listening Experience
The Sonos Arc Ultra uses advanced processing to create five horizontal phased-array channels, delivering sound to your ears from all directions at exactly the right moment. This is what separates a real Dolby Atmos setup from a soundbar that just claims "virtual surround."
True 3D Sound with Dolby Atmos
With 9.1.4 spatial audio across 11 drivers on the Arc Ultra alone, this system renders every whisper, footstep, and explosion with dramatic clarity, detail, and depth. The upward-firing drivers bounce sound off your ceiling to create a genuine multi-dimensional soundstage that moves around the room instead of just sitting in front of you.
Trueplay Tuning — Calibrated to Your Room
No two living rooms sound the same. Trueplay automatically tunes the Arc Ultra and Era 300 speakers to the unique acoustics of your space, calibrating the height channels for precise, accurate localisation so every seat gets the full effect.
Wireless Rear Surround with Era 300
The two Era 300 speakers eliminate the need for running speaker wire across your living room. Placed behind or beside your seating area, they add dedicated rear and height channels that complete the immersive Atmos bubble the Arc Ultra starts.
Deep, Controlled Bass from the Sonos Sub Gen 4
The included Sonos Sub adds a dedicated low-frequency channel so dialogue and effects stay clean while bass hits with real physical impact — essential for action movies, live concerts, and gaming.
Crystal-Clear Dialogue, Always
Arc Ultra was tuned with the help of Oscar-winning sound engineers to emphasise the human voice, and its built-in Speech Enhancement mode (accessible from the Sonos app) clarifies dialogue further whenever characters whisper or on-screen action intensifies.
Effortless Setup and Everyday Streaming
Connection is a single HDMI eARC cable to your TV, with control available through your TV remote, the Sonos app, voice assistants, or Apple AirPlay 2. When the TV is off, the same system doubles as a serious music setup for streaming from your favourite services.

Price, Warranty & Buying This in India
The Sonos Ultimate Immersive Set with Arc Ultra is priced at ₹2,69,999 (MRP, inclusive of GST) and comes backed by a 2-year manufacturer warranty in India, along with 8mm's 7-day return and replacement policy.
