A quick and easy way to wall-mount a pair of Sonos speakers These slim, non-adjustable mounts from Sanus hold a pair of Sonos Era 300 speakers on the wall. They install easily with just a few common household tools, and it only takes about 15 minutes to get the job done. The mounts can be affixed to wall studs, concrete, or drywall.
