The Sonos Sub is not a small piece of equipment.
It is a substantial, beautifully designed wireless subwoofer that happens to weigh around 16 kilograms and take up a noticeable amount of floor space wherever you place it. For most people in most living rooms, that means it ends up somewhere nearby the television, either tucked beside the TV cabinet, pushed under a coffee table, or sitting in a corner where it is partially hidden but never completely invisible.
And for a lot of those people, that placement works fine. The Sub sounds exceptional wherever it goes, and Sonos has designed it to handle a wide range of room positions without major compromise to the bass performance.
But then there is the group of people who look at their living room and think there has to be a better way. The people who want to reclaim that floor space. The people whose room layout genuinely does not have a good spot for a large floor standing subwoofer. The people doing a custom home installation where the goal is invisible, integrated audio with no equipment sitting on the floor.
For every one of those people, the Flexson Wall Mount for Sonos Sub exists. And it is the only product of its kind built specifically for the Sonos Sub.
What Is the Flexson Wall Mount for Sonos Sub?
The Flexson Wall Mount for Sonos Sub is designed and built in Britain specifically for the Sonos Sub. The bracket is engineered to perfectly match the size and style of the Sonos Sub and is made from superior quality steel with a matte powder coat finish. It is a single mount with an integrated hook and flat to wall design, featuring 0.1 inch steel construction for durability, with rubber isolators included to prevent unwanted subwoofer vibration and resonance.
In simple terms, it is a wall bracket that holds the Sonos Sub flush against the wall, keeps it completely stable, prevents vibration from transferring into the wall structure, and manages the power cable neatly so nothing is hanging visibly once the installation is complete.
It is available in black to match the black Sonos Sub. It is the kind of product that solves a very specific problem extremely well, and once you know it exists, placing the Sonos Sub on the floor starts to feel like an unnecessary compromise.
The Design: Flat to the Wall, Invisible in the Room
The flat to wall design of the Flexson Sub mount is the detail that makes the biggest visual difference.
Unlike some speaker mounts that hold equipment at an angle or on an arm projecting out from the wall, this bracket positions the Sonos Sub as close to the wall surface as physically possible. From the side, the Sub appears to sit almost directly on the wall itself rather than being suspended on a visible bracket structure.
The wall bracket holds your Sonos Sub flat against the wall and offers a cable management hanger and cover for a neat installation.The cable management cover conceals the power cable where it exits the Sub and runs down to the wall outlet, so the finished installation looks considered and clean rather than like a speaker hanging on a hook with a cable trailing from it.
The matte powder coat finish on the steel bracket matches the finish of the Sonos Sub itself. When the Sub is mounted and sitting flat against the wall, the bracket essentially disappears behind the speaker. You see the Sub, not the mount holding it. That visual outcome is exactly what a purpose built mounting accessory should deliver.
Steel Construction: Built to Hold Something Heavy
The Sonos Sub is not a light product. Asking a wall mount to hold it securely day after day, at whatever height you choose to install it, requires a bracket that is genuinely engineered for the task rather than just designed to look adequate.
The Flexson Wall Mount features 0.1 inch steel construction for durability.That is a meaningful gauge of steel for a wall bracket and it gives the mount the rigidity and load bearing capacity that the weight of the Sonos Sub demands. The bracket does not flex under load. It does not creak or shift when the subwoofer is playing at volume and producing the kind of physical vibration that a powerful woofer generates.
Users who have mounted the Sonos Sub with this bracket describe it as sturdy and strong, with complete confidence that it will hold the heavy Sub securely over the long term. That confidence is earned by the quality of the steel and the engineering behind the bracket rather than just by how it looks in a product photograph.
For anyone who is going to mount a subwoofer at a significant height above the floor, that build quality is not a nice to have. It is essential.
Rubber Isolators: The Feature That Protects Your Walls and Your Sound
This is the detail that separates the Flexson Sub mount from any generic wall bracket you might consider using instead, and it is worth understanding properly.
A subwoofer produces bass frequencies by moving large volumes of air through powerful driver excursion. That physical movement creates vibration not just in the air around it but in the structure it is attached to. Place a subwoofer directly against a wall with no isolation between them and that wall becomes a resonating surface. The vibration transfers into the plaster, the brick, the structure, and comes back as unwanted colouration in the bass. Neighbours in adjacent rooms or floors also become very aware of your listening sessions.
Rubber isolators are included to prevent unwanted subwoofer vibration and resonance. These isolators sit between the Sonos Sub and the bracket itself, absorbing the mechanical vibration that the subwoofer generates and preventing it from transferring into the wall surface. The Sub moves the air. The vibration stays with the Sub. The wall stays quiet.
The integrated rubber isolators, which function similarly to suction cups, prevent subwoofer vibration and resonance from transferring into the wall structure. This keeps the bass clean and tight, protects the wall surface from long term vibration damage, and makes wall mounted subwoofer installation genuinely practical rather than just theoretically possible.
It is a small engineering detail that makes a meaningful difference to both the sound quality and the practicality of the installation.
Installation: What You Need to Know Before You Start
The Flexson Sub mount is designed for installation by someone comfortable with basic DIY wall fixings. It is not a complex installation but because of the weight of the Sonos Sub, it is worth doing properly.
The Flexson Sub wall bracket attaches to your wall studs using four wood screws, which are not included. Four wall anchors, also not included, will also be required if you mount the bracket to drywall only.
The recommendation to fix into wall studs wherever possible is important and worth following. A subwoofer this heavy mounted on wall anchors in drywall alone is not best practice. Locating the studs before you mark your fixing positions and anchoring into them gives the installation the mechanical foundation it needs to hold the Sub safely and securely at whatever height you choose.
Once the bracket is installed on the wall, the Sonos Sub can be positioned and secured onto the wall mount bracket. The integrated hook design means the Sub locates onto the bracket cleanly and sits flat against the wall without requiring additional adjustment.
The absence of mounting hardware in the box is the one practical note worth mentioning upfront so you are not making an unexpected trip to the hardware store on installation day. Pick up appropriate wood screws and wall anchors for your specific wall type before you start and the rest of the process is straightforward.
The Real World Benefit: Space, Flexibility and a Cleaner Room
People choose to wall mount their Sonos Sub for different reasons and the Flexson mount serves all of them well.
For rooms where floor space is genuinely limited, getting the Sub off the floor and onto the wall creates meaningful breathing room in the layout. A Sub mounted at mid wall height behind or beside the sofa is acoustically effective, physically out of the way, and visually far less intrusive than a large oval subwoofer sitting on the floor demanding to be noticed.
For custom home installations where the design brief is completely integrated audio with no visible equipment at floor level, the Flexson Sub mount is a necessary part of achieving that outcome. Paired with the Sonos Arc or Beam above the television and Era 100 units positioned as surround speakers, a wall mounted Sub completes the picture of a room where the audio system is present in sound but invisible in form.
And for people who simply want to tidy up their setup, remove a tripping hazard, or stop the Sub from creeping away from the wall every time it plays a particularly heavy bass line, wall mounting solves all of those problems permanently.
Customers describe the result of mounting the Sonos Sub with the Flexson bracket as secure and snug against the wall, with no rattles, no impact on performance, and great bass. That consistent real world feedback is exactly what you want to hear from a product that is going to be holding a premium subwoofer on your wall.
Who Should Buy the Flexson Wall Mount for Sonos Sub?
Anyone who owns a Sonos Sub and wants to mount it on the wall rather than leave it on the floor has essentially one purpose built option and this is it.
It is the right choice for anyone doing a custom residential or commercial audio installation where floor mounted equipment is not part of the design brief. It makes sense for anyone in a smaller living space where floor real estate is genuinely precious. It is ideal for anyone who wants the Sub positioned at a specific height in the room for acoustic or aesthetic reasons. And it is worth considering simply for the cleanliness of the installation outcome it delivers compared to any improvised mounting solution.
The Flexson Wall Mount for Sonos Sub is not an impulse purchase. It is the practical solution to a specific problem, engineered properly, built from quality materials, and designed to make a premium subwoofer look and perform exactly as it should in a wall mounted installation.

FAQ
Q1. What is the Flexson Wall Mount for Sonos Sub and what does it do?
The Flexson Wall Mount for Sonos Sub is a purpose built wall bracket designed specifically for the Sonos Sub subwoofer. It holds the Sub flat against the wall using a steel hook and flat to wall bracket design, includes rubber isolators to prevent vibration transfer into the wall, and features integrated cable management to keep the power cable neatly concealed. It is the only dedicated mounting solution built specifically for the Sonos Sub.
Q2. Is the Flexson Wall Mount strong enough to hold the Sonos Sub safely?
Yes. The bracket is constructed from 0.1 inch steel, which gives it the rigidity and load bearing capacity required to hold the weight of the Sonos Sub securely over the long term. Users who have installed the bracket consistently describe it as sturdy, strong, and completely stable with no flex, creaking, or movement once properly fixed to the wall. Fixing into wall studs rather than drywall alone is strongly recommended for the safest installation.
Q3. What are the rubber isolators and why do they matter?
The rubber isolators sit between the Sonos Sub and the bracket itself. Their function is to absorb the mechanical vibration that the subwoofer generates during playback and prevent it from transferring into the wall structure. Without isolation, a wall mounted subwoofer can cause the wall surface to resonate, which colours the bass sound and creates unwanted vibration in the room and adjacent spaces. The rubber isolators keep the bass clean and protect the wall from long term vibration effects.
Q4. Does the Flexson Wall Mount for Sonos Sub come with the screws and fixings needed for installation?
No. The mounting hardware including wood screws and wall anchors are not included with the bracket and need to be sourced separately before installation. The appropriate screw and anchor type will depend on your specific wall construction. For walls with timber studs, wood screws fixed into the studs are recommended. For masonry or brick walls, appropriate masonry anchors will be required. Having the correct fixings for your wall type ready before you start makes the installation process straightforward.
Q5. Can the Sonos Sub be mounted at any height on the wall?
Yes. The bracket can be fixed at any height on the wall that suits your room layout, aesthetic preferences, and acoustic requirements. Many users mount the Sub at mid wall height beside or behind their seating position, which keeps it acoustically effective while getting it completely off the floor. Others mount it lower, closer to floor height, to maintain a similar acoustic position to floor placement while keeping it fixed against the wall rather than free standing.
Q6. Does wall mounting the Sonos Sub affect its sound quality?
No, wall mounting does not negatively affect the sound quality of the Sonos Sub. The rubber isolators prevent vibration transfer into the wall, which actually protects the sound quality compared to a poorly isolated floor placement. The Sonos Sub is designed to perform well in a range of positions and the TruePlay calibration in the Sonos app can be run after installation to optimise the overall system performance for the Sub’s new position in the room.
Q7. Is the Flexson Wall Mount for Sonos Sub compatible with all generations of the Sonos Sub?
The Flexson Wall Mount is designed for the Sonos Sub. It is worth confirming compatibility with the specific generation of Sonos Sub you own, particularly if you have the newer Sub 4, before purchasing, as the physical dimensions may vary between generations.
Q8. Does the Flexson Wall Mount for Sonos Sub include cable management?
Yes. The bracket includes a cable management hanger and cover that conceals the power cable where it exits the Sub and runs toward the wall. This gives the installation a clean, finished appearance rather than leaving the power cable hanging visibly from the mounted subwoofer. For a truly seamless result, having the power cable run through the wall to a concealed outlet behind the Sub will give the cleanest possible finish.
Q9. Can I install the Flexson Wall Mount for Sonos Sub myself or do I need a professional?
The installation is designed to be completed by someone comfortable with basic wall fixing work. You will need to locate wall studs, drill fixing holes, and attach the bracket with appropriate wood screws or wall anchors. Because the Sonos Sub is heavy, fixing into wall studs rather than drywall alone is strongly recommended for safety. If you are not confident working with wall fixings at the required load rating, having a professional install the bracket is worth the peace of mind.
