Sonos Arc Ultra 9.1.4 Dolby Atmos Soundbar
Sonos Arc Ultra Dolby Atmos soundbar
The Sonos Arc Ultra is Sonos' flagship soundbar: 9.1.4 Dolby Atmos from 14 Sonos-engineered drivers, including the new Sound Motion™ woofer for deeper bass, plus AI Speech Enhancement for clearer dialogue. It connects to your TV with a single HDMI eARC cable and works with your existing TV remote.
It's best suited to TVs 55" and larger, and you can add a Sonos Sub and surround speakers later for a full home cinema. Buy it from Jennings Sound & Vision, an authorised Sonos dealer on Fleet Road, Fleet since 1996, and hear it on demo in our showroom first.

Hear Arc Ultra in our Fleet showroom
Arc Ultra is on demo in our showroom at 185 Fleet Road, so you can hear 9.1.4 Dolby Atmos for yourself, and compare it with Beam Ultra, before you decide.
No appointment is needed: just walk in. For a bigger home cinema project, you can book a time so a member of the team is free to give you our full attention.
Sound Motion™: bass you can feel
Arc Ultra introduces Sound Motion™, a new woofer design from Sonos that packs more bass into a flat, compact enclosure. The result is deeper, more powerful bass and more detail across every frequency, from a soundbar only 75 mm tall.
Sonos rates it at up to double the bass output of the original Arc.¹
9.1.4 Dolby Atmos, from one soundbar
Arc Ultra places sound all around you, with upward-firing drivers adding height so rain falls from overhead and helicopters pass above.
With 14 drivers and 15 amplifiers working together, it delivers a 9.1.4 spatial audio experience from a single cable to your TV.²
Dialogue you won't miss
AI Speech Enhancement picks out voices and lifts them above the action. Choose from four levels in the Sonos app, depending on how much help you want.
Night Sound reduces loud effects and brings up quieter detail for late-night viewing, and Trueplay™ tunes Arc Ultra to the acoustics of your room using an iOS or Android device.
Soundbar today. Full home cinema whenever.
Start with Arc Ultra on its own, then build on it whenever you like, in any order. Every Sonos speaker connects to Arc Ultra wirelessly: each one just needs a power socket, with no speaker cables to run around the room.
Choose from three upgrades below: deeper bass, surround sound, and headphones for late-night viewing.
Build your Arc Ultra system
Three ways to take Arc Ultra further. Add one now, or come back for more later.
Option 1
Add deep, impactful bass
Arc Ultra's Sound Motion™ bass is impressive on its own, but a Sonos Sub adds the deep, physical rumble that makes explosions and film scores hit hard.
Sub 4 is the natural partner for Arc Ultra in most living rooms. Sub Mini suits smaller rooms.
Option 2
Add surround sound
Add a matching pair of speakers behind your seating for full surround sound, with effects moving all around the room.
Fixed surrounds: Era 300 for Dolby Atmos height effects from behind, or Era 100 SL for a simpler, more affordable setup.
Portable surrounds: two Play or two Move 2 speakers act as rears for film night, then come off the TV system to use around the house or garden.
Option 3
Listen on headphones
Watching late at night or don't want to disturb anyone? TV Audio Swap sends the sound from Arc Ultra to your Sonos headphones with one press.³
Choose Ace for premium noise cancelling, or Ace Ultra for Sonos' best.
Designed to disappear
Arc Ultra sits neatly on a TV unit or mounts on the wall below your TV. The Sonos Arc Ultra Wall Mount holds it close to the wall for a near-seamless look, and Arc Ultra detects when it's wall-mounted and adjusts its sound to suit.
Professional installation available
Our installation team can wall-mount your Arc Ultra and TV, hide the cables, connect it to your TV and Sonos system, and set up a Sub and surrounds, so everything works perfectly from day one.
We cover Fleet, Farnborough, Aldershot, Farnham, Camberley and the surrounding area. Installation is a chargeable service, and we'll quote for exactly what you need.

Sonos Arc Ultra review: our take
Is it worth buying? If you want the best soundbar Sonos makes and your TV is 55" or larger, yes. Sound Motion gives Arc Ultra noticeably deeper bass than the original Arc, and the 9.1.4 Dolby Atmos is wide and convincing for a single soundbar. AI Speech Enhancement is a real help if you struggle to follow dialogue.
It also grows with you: start with the soundbar, then add a Sub and surrounds later as budget allows.
If your room is smaller or your TV is under 55", Beam Ultra gives you true Dolby Atmos for £300 less. Both are on demo in our Fleet showroom, so come and compare them, or call us on 01252 811800.

Frequently asked questions
How much is the Sonos Arc Ultra in the UK?
The SRP is £999. Check this page for our current price, and ask about our price match if you've seen it cheaper at another authorised UK retailer.
Should I buy Arc Ultra or Beam Ultra?
Choose Arc Ultra for a TV 55" or larger and the biggest, most immersive sound Sonos makes (9.1.4 Dolby Atmos with Sound Motion bass). Choose Beam Ultra (SRP £699) for a smaller room or a TV up to around 65" where a compact 750 mm soundbar fits better. Both are on demo in our Fleet showroom.
Is Sonos Arc Ultra one of the best Dolby Atmos soundbars in the UK?
It's Sonos' best soundbar and one of the strongest all-in-one Dolby Atmos soundbars you can buy, thanks to its 9.1.4 sound, Sound Motion bass and AI Speech Enhancement. The best choice depends on your room and TV, so come and hear it against Beam Ultra in our showroom.
Do I need a Sonos Sub with Arc Ultra?
No. Arc Ultra has strong bass on its own thanks to Sound Motion. Adding a Sub 4 or Sub Mini gives deeper, more physical bass for films and music, and you can add one at any time.
Which surround speakers work with Arc Ultra?
A pair of Era 300 or Era 100 SL speakers make fixed wireless rear surrounds. For flexible, portable surrounds, a pair of Sonos Play or Move 2 speakers can be used as rears for film night and then taken around the house or garden. None of them need speaker cables back to the soundbar.
Will Arc Ultra work with my TV?
Arc Ultra connects to TVs with an HDMI eARC or ARC port, using the HDMI cable in the box. For older TVs without HDMI ARC, an optical adapter is available separately. Dolby Atmos needs an HDMI eARC connection and Dolby Atmos content.
Can you wall-mount and install Arc Ultra for me?
Yes. Our installation team can wall-mount Arc Ultra and your TV, hide the cables, and connect and set up your whole Sonos system. Installation is a chargeable service, covering Fleet, Farnborough, Aldershot, Farnham, Camberley and the surrounding area.
Can I hear Arc Ultra before I buy?
Yes. Arc Ultra is on demo in our showroom at 185 Fleet Road, Fleet GU51 3BL. No appointment is needed, or you can book a time.
Can I get money off with the Sonos Trade Up offer?
If you own an eligible older Sonos product, you can get 30% off the SRP of Arc Ultra and keep your old product. See our Sonos Trade Up page for the qualifying models.
Do you deliver Sonos Arc Ultra?
Yes. Delivery is free on orders over £100, both locally and to anywhere on the UK mainland. You can also collect from our shop at 185 Fleet Road, Fleet GU51 3BL.
