Audio T Verdict
The Flexson Wall Mount for Sonos Arc is more than a simple strip of metal for hanging the soundbar beneath a television. Its most important feature is the 30mm forward step built into the bracket, positioning the Arc farther into the room so that the television is less likely to obstruct its upward-firing Dolby Atmos speakers.
That matters because Arc relies on sound directed upwards as part of its immersive presentation. If the television projects significantly in front of the soundbar, particularly when both are wall mounted, it can interfere with that upward sound path.
The Flexson bracket itself is deliberately simple. There is no tilt, swivel or extending mechanism. Instead, it creates a secure fixed position beneath the TV with multipoint wall fixing and a purpose-built interface for the Arc.
Flexson uses high-grade steel and splits the main bracket into two sections for compact packaging and straightforward assembly. Once installed correctly, the soundbar sits securely with its controls facing upwards and its connections remaining accessible from behind.
Flexson also describes the mount as optimised for Sonos Trueplay. Once the Arc is installed and connected, running Trueplay allows the soundbar to account for the acoustic characteristics of its new position and listening room.
For anyone wall mounting an original Sonos Arc beneath a television, this is a neat alternative to the official Sonos bracket, particularly where the additional 30mm forward offset helps clear the face of the TV.

Sonos Arc Is Not Included
This product is the Flexson wall mount only.
The Sonos Arc soundbar shown in product photography is purchased separately.
Designed for the Original Sonos Arc
The bracket was developed specifically around the original Sonos Arc cabinet and mounting arrangement.
It is not a generic soundbar shelf and should not be assumed to fit another soundbar simply because its dimensions appear similar.
What About Sonos Arc Ultra?
The Arc Ultra replaced the original Arc at the top of the current Sonos soundbar range.
There is currently mixed regional Flexson information regarding this particular bracket. Some Flexson European channels now list the same product code for Arc and Arc Ultra, while other current Flexson product pages continue to specify Sonos Arc only.
Confirm Arc Ultra Compatibility Before Ordering
Audio T recommends confirming current UK Flexson compatibility before purchasing this bracket specifically for a Sonos Arc Ultra.
30mm Forward Step
The defining feature of the Flexson design is its 30mm step.
This moves the Sonos Arc approximately 30mm farther forward relative to the television rather than placing the soundbar as close to the wall as possible.
Why Move the Arc Forward?
Sonos Arc contains upward-firing drivers used for Dolby Atmos height effects.
If a television projects significantly in front of the soundbar, the lower edge of the screen can partially obstruct the path of sound travelling upwards.
Flexson's 30mm offset helps bring the Arc forward so those speakers have a clearer path towards the ceiling.
The 30mm Step Is About the TV, Not Wall Clearance
The Flexson measurement refers to positioning the soundbar forward relative to the face of the television.
It should not be confused with the vertical clearance Sonos recommends between the top of Arc and the bottom of the TV.
Leave Clearance Below the Television
Sonos recommends at least approximately 102mm between the top of Arc and the bottom of the television.
This helps provide space for the soundbar's upward-firing acoustics and keeps its touch controls accessible.
Do not mount the Arc hard against the bottom edge of the television simply because the bracket physically allows it.
Keep the Ends Clear Too
Sonos recommends keeping each end of Arc approximately 300mm or more from a side wall or other obstruction where practical.
This gives the side-firing elements of the soundbar more freedom to interact with the room.
Dolby Atmos and Wall Position
Arc creates its immersive presentation using a combination of:
- Front-firing drivers
- Side-directed sound
- Upward-firing height channels
- Digital signal processing
- Room interaction
A clean physical installation therefore matters as well as the connection between the Arc and television.
Optimised for Trueplay
Flexson describes the wall mount as optimised for Sonos Trueplay.
After the Arc has been installed in its final position, run Trueplay calibration using a supported device.
Trueplay analyses the way sound behaves in the listening room and adjusts the Arc accordingly.
Run Trueplay After Moving the Arc
If the soundbar was previously sitting on furniture and has now been wall mounted, its acoustic surroundings have changed.
Re-running Trueplay after installation is therefore worthwhile.
Flexson Mount Versus Official Sonos Arc Mount
Both provide purpose-built wall mounting, but they take slightly different approaches.
Flexson Arc Wall Mount
- Purpose-built for Arc
- 30mm forward step
- High-grade steel
- Multipoint fixing
- Fixed position
- Optimised for Trueplay
- Approx. 675mm wide
Official Sonos Arc Wall Mount
- Designed by Sonos
- Very close-to-wall installation
- Arc detects the official mount
- Automatic EQ adjustment for wall placement
- Fixed position
- Near-invisible installation
Compare the official Sonos Arc Wall Bracket.
Do Not Assume the Flexson Mount Triggers Sonos Mount Detection
Sonos specifically states that Arc detects its own official wall mount and adjusts EQ accordingly.
Flexson describes this bracket as optimised for Trueplay, but does not currently advertise the same automatic Sonos wall-mount detection function.
Run Trueplay after installation rather than assuming the bracket itself changes the Arc's internal EQ.
Fixed Wall Mount
The Flexson Arc Wall Mount is a fixed bracket.
It does not provide:
- Tilt adjustment
- Swivel adjustment
- Pull-out extension
- Movement with an articulated television mount
Choose the wall position carefully before drilling.
Need the Arc to Move With the Television?
Flexson also offers a different TV Mount Attachment designed to connect Arc to a compatible television wall-mount installation.
That type of solution is more suitable where an articulated TV is expected to move and the soundbar should remain aligned with the screen.
High-Grade Steel Construction
The bracket is precision engineered from high-grade steel.
The Arc itself weighs more than 6kg, so the wall and fixing method must be capable of supporting the complete installed load securely.
Multipoint Wall Fixing
Flexson uses several mounting points across the bracket rather than relying on one central fixing.
This distributes the load across a wider section of the wall and provides flexibility when selecting suitable fixing positions.
Two-Part Main Bracket
The main wall bracket is supplied as a two-part assembly.
This allows the long Arc-specific mount to be supplied in more compact packaging while creating the required installed width once assembled.
Check the Wall Construction
Before drilling, identify whether the mounting surface is:
- Brick
- Concrete
- Blockwork
- Timber studwork
- Plasterboard
- Another wall construction
The fixing method should be chosen for the actual structure supporting the bracket rather than the decorative wall surface alone.
Check for Hidden Services Before Drilling
Make sure the intended fixing positions are clear of concealed electrical wiring, water pipes, heating pipes and other services.
If wall construction or safe installation is uncertain, use a competent installer.
Plasterboard Installations
A wall-mounted Arc creates considerably more load than a picture frame.
Where possible, secure the bracket to suitable structural timber or use fixings specifically rated for the wall construction and total installed weight.
Do not rely on lightweight general-purpose plasterboard plugs.
Plan Cable Routing Before Installation
Arc requires:
- Mains power
- HDMI connection to the television
An Ethernet cable may also be used where a wired network connection is preferred.
Plan how these cables will reach the soundbar before permanently fixing the bracket.
HDMI ARC or eARC
For normal TV integration, connect Sonos Arc to the television's HDMI ARC or HDMI eARC connection.
HDMI eARC is particularly useful where compatible televisions and sources are being used with higher-bandwidth home cinema audio formats.
Keep the Connections Accessible
Allow enough room behind the soundbar to connect:
- HDMI
- Power
- Ethernet if required
A tidy installation should not place excessive strain on cables or connectors.
Do Not Trap the Power Cable
When lowering the Arc onto the wall-mount hardware, check that the mains and HDMI cables are not trapped, pinched or sharply bent behind the soundbar.
Dimensions
Flexson specifies the wall mount itself at approximately:
- Height: 40mm
- Width: 675mm
- Depth: 32mm
The 30mm forward step relates to the final relationship between Arc and the television rather than simply being the physical depth measurement of the bare bracket.
Approximately 0.9kg
The Flexson bracket weighs approximately 0.9kg before the Sonos Arc is installed.
The fixing method must therefore be rated for the combined soundbar and bracket load, not merely the bracket's own weight.
Black and White Versions
Flexson offers the Arc wall mount in Black and White.
The corresponding product codes are:
- Black: FLXSARWM1021
- White: FLXSARWM1011
Engineered in the UK
Flexson describes the Arc wall mount as precision engineered in the UK.
The bracket is specifically shaped around the Sonos Arc rather than being a generic soundbar shelf.
Mount Beneath the Television
The most common installation places Arc centrally beneath the television.
Before drilling, check:
- TV centre line
- TV lower-edge position
- 102mm minimum recommended gap above Arc
- Availability of mains power
- HDMI cable route
- Clearance at both ends of the Arc
Use a Level
A soundbar more than a metre wide makes even a small installation error visually obvious.
Use a suitable spirit level when marking and securing the bracket rather than relying on the television cabinet or ceiling line as a visual guide.
Wall-Mounted TV or TV on Furniture?
The Flexson bracket can be useful in either situation.
Wall-Mounted Television
- Creates a clean combined installation
- Arc can sit centrally below the screen
- 30mm step helps bring Arc forward
- Cables can be planned together
- TV depth should be considered carefully
Television on Furniture
- Arc can still be wall mounted independently
- Frees space on the TV cabinet
- Can avoid blocking the bottom of the screen
- Requires suitable wall position behind the furniture
Can the Arc Be Mounted Above the TV?
Sonos's standard guidance and the Flexson design are primarily intended around positioning Arc below the television with its touch controls and upward-firing drivers correctly orientated.
For normal installations, beneath the TV is the recommended arrangement.
Keep the Arc Horizontal
Sonos Arc is designed to operate horizontally.
Do not install it vertically or on its side.

Frequently Asked Questions
Which soundbar is this bracket designed for?
The original Sonos Arc.
Does it fit Sonos Arc Ultra?
Some current Flexson European channels list the same bracket for Arc Ultra, while other Flexson regional pages still specify the original Arc only. Audio T recommends confirming current UK compatibility before ordering specifically for Arc Ultra.
Is the Sonos Arc included?
No. This product is the wall mount only.
Why does the bracket move Arc 30mm forward?
The forward step helps place Arc's upward-firing speakers in front of the television rather than allowing the bottom of the screen to obstruct their acoustic path.
Is the bracket 30mm deep?
The bare bracket is specified at approximately 32mm deep. The separate 30mm figure describes Flexson's intended forward relationship between the Arc and television.
How far should Arc be below my television?
Sonos recommends at least approximately 102mm between the top of Arc and the bottom of the television.
Why does Arc need space below the TV?
Clearance helps avoid obstruction of the upward-firing acoustic system and keeps the soundbar controls accessible.
How much clearance should I leave at the sides?
Sonos recommends keeping each end approximately 300mm from a wall or other obstruction where possible.
Does it tilt?
No. It is a fixed wall mount.
Does it swivel?
No.
Can I pull the soundbar forward?
No. The 30mm offset is built into the fixed mounting geometry rather than being an adjustable extension.
Does the bracket work with a moving TV wall mount?
This is a fixed wall bracket. Flexson offers separate TV-mount attachment products where the soundbar needs to move with an articulated television.
What is the bracket made from?
High-grade steel.
How wide is it?
Approximately 675mm.
How high is it?
Approximately 40mm.
How deep is it?
Approximately 32mm.
How much does it weigh?
Approximately 0.9kg.
Why is the bracket narrower than the Sonos Arc?
The bracket engages with the mounting points on the rear of Arc rather than needing to span the entire width of the soundbar.
What is multipoint fixing?
The bracket provides several wall-fixing positions so the installed load can be distributed securely across the mounting surface.
Does it come in one piece?
The main bracket uses a two-part assembly.
What colours are available?
Black and White.
What is the black product code?
FLXSARWM1021.
What is the white product code?
FLXSARWM1011.
Does Trueplay still work when Arc is wall mounted?
Yes. Flexson specifically describes the bracket as optimised for Trueplay, and Audio T recommends running Trueplay again once the Arc is installed in its final position.
Does the Flexson bracket automatically change Arc's EQ?
Flexson does not advertise the same automatic wall-mount detection that Sonos specifically documents for its own official Arc bracket. Run Trueplay after installation rather than assuming an automatic change has occurred.
Can I connect the Arc over HDMI?
Yes. Sonos Arc normally connects to a compatible television using HDMI ARC or HDMI eARC.
Can I use Ethernet?
Yes. Arc includes an Ethernet connection for optional wired networking.
Does the bracket include cable management?
Flexson does not describe this fixed wall mount as having a separate enclosed cable-management channel. Plan the power and HDMI cable routes as part of the installation.
Can I fit it to brick?
Yes, using a fixing method appropriate to the wall and installed load.
Can I fit it to plasterboard?
Potentially, but suitable structural fixing is essential. Fixing into timber or using properly rated specialist fixings is preferable to relying on lightweight general-purpose plugs.
Can I mount Arc vertically?
No. Sonos Arc is designed for horizontal installation.
Can I mount it above the TV?
The standard Sonos and Flexson installation is intended around horizontal mounting below the television. Beneath the screen is the recommended arrangement for normal use.
Is there an official Sonos alternative?
Yes. Audio T also sells the official Sonos Arc Wall Bracket.
