Wall-mounting your Sonos Arc can not only enhance your room’s aesthetics but also significantly improve your Dolby Atmos experience — if done correctly. Because the Sonos Arc relies on upfiring speakers to create height effects, improper positioning can degrade audio clarity and spatial immersion.
This guide offers step-by-step tips for mounting the Arc to optimize height channel performance, sound dispersion, and room acoustics.
Tools & Materials You’ll Need
Sonos Arc (of course)
Official Sonos Wall Mount Kit (or VESA-compatible bracket)
Stud finder
Level and measuring tape
Power drill and drywall anchors
Optional: cable cover or in-wall routing kit
Best Height & Placement for Dolby Atmos
Recommended Wall-Mount Height
Ideal distance from bottom of TV: 2–4 inches
Arc height from floor: Approximately 42–48 inches
Why This Matters:
The Arc’s upfiring speakers need clear vertical paths to reflect off the ceiling
Mounting too high disrupts the height cue illusion essential to Atmos
Wall Mounting Steps
Find Wall Studs
Use a stud finder for secure anchor points
Align and Mark Drill Points
Ensure level positioning — the Arc is symmetrical and sleek, so misalignment is noticeable
Drill and Install Brackets
Use included screws or wall anchors as needed
Mount the Sonos Arc
Slide securely onto the bracket; test stability
Cable Management
Route HDMI eARC and power cable using wall plates, covers, or in-wall solutions
Maximizing Sound Quality Post-Mount
Run Trueplay Tuning (iOS only)
Re-calibrates Arc’s sound for wall reflection behavior
Turn off TV speakers to avoid echoing
Adjust TV’s eARC settings for optimal sync and Atmos pass-through
Wall Mount vs Tabletop Placement
| Factor | Wall-Mounted | Tabletop Setup |
| Atmos Performance | ✅ Better height effects | ❌ May block upfiring path |
| Space Efficiency | ✅ Frees up console space | ❌ Takes up shelf depth |
| Vibration Management | ✅ No surface resonance | ❌ Prone to surface buzz |
Final Tips for Sonos Arc Placement
Avoid mounting under open shelving
Ceiling height between 7–10 ft offers best results for Atmos
Use ARC/eARC HDMI input on TV — not optical — for Dolby Atmos support
