Solid, well made, does the job.

Crutchfield Customer Review (What's this?)

Super heavy duty mount. Does the job with no problems. I was only able to catch a stud with 2 screws due to the spacing but installed anchors with the other 2 screws and it holds the subs weight just fine. Crutchfield sells this cheaper than everyone else online with free shipping. Received it quickly. Very happy.

Pros: Does what it claims, well built, perfect fit.

Cons: Zero cons.

Crutchfield Customer Review (What's this?)

Good mount, easy to install, but expensive. I give it 4 stars because the mount doesn't come with any screws.

Perfect mount. Sleek, elegant, and barely noticeable.




Hands-on research

Product Research


Wall Bracket for Sonos Sub: The Flexson Sonos Sub Wall Bracket is designed and built-in Britain specifically for the Sonos Sub (sold separately). This Flexson wall bracket is engineered to perfectly match the size and style of the Sonos Sub. The bracket is made from superior-quality steel with a matte black powder-coat finish. The wall bracket holds your Sonos Sub flat against the wall and offers a cable management hanger and cover for a neat installation. Integrated rubber isolators (suction cups) prevent subwoofer vibration and resonance.

Installation: The Flexson Sonos Sub Wall Bracket attaches to your wall-studs using four wood screws (not included); four wall anchors (not included) will also be required if you mount the bracket to drywall only. Once the bracket is installed on the wall, your Sonos Sub can be positioned and secured onto the wall-mount bracket.

1 question already asked

Not at all. Only difficulty is trying to hide the electoral cord. If you have a electrical outlet near where you want to out the sub, I mounted the sub plate over the electrical outlet. [ David  Sep 04, 2016 ]
Actually I don't know. I haven't mounted it yet. [ William  May 14, 2015 ]
