Sonos SONOS-ARC-WM Wall Mount for Arc
Sonos Wall Mount for Arc
Securely affix your soundbar to the wall with this mount, designed and made by Sonos.
Arc smartly detects (via magnets) when it is attached to the mount and automatically adjusts the EQ to temper bass resonance from the wall.
For the best sound, mount Arc four inches from the bottom of your TV.
