Hi @DavidAW, sorry for the late response and welcome to the community.

If you’re asking for any recommended mounts for the TV, I would suggest getting in touch with the manufacturer.

You could also refer to any electronic store that sells TV mounts.

However, for the Sonos Arc, we do sell a wall mount for it on our website. 

Since there are up-firing speakers on the Sonos Arc, we can’t mount it above the TV like the Playbar.

If you have other concerns, feel free to reach out.

Not cheap, but this seems like it would work.  https://www.bestbuy.com/site/sanus-premium-swivel-tv-base-for-most-32-60-tvs-black/5463304.p?skuId=5463304&ref=212&loc=1&extStoreId=343&ref=212&loc=1&gclid=Cj0KCQjwo6D4BRDgARIsAA6uN19RDbQUXs3sk9IK0YRRTdt64HY-2JTZm9qZvh1BT9PdUsSJk4uyIvsaAgTMEALw_wcB&gclsrc=aw.ds

Here's a cheaper option: https://www.amazon.com/PERLESMITH-Universal-Swivel-Stand-Base/dp/B07T72QG3K/ref=sr_1_13?dchild=1&keywords=stand+for+55%22+tv&qid=1594438467&sr=8-13

I used IKEA Lack shelves to lift my TV up far enough so the screen wasn’t obscured.

They sit on the cabinet, and support the legs of the TV. 

I bought this stand from amazon...

note:  the top pieces that are slide adjustable, I removed and did not use.

I have the C9 65” model, mine has the actual stand then the long faceplate that reflects the TV’s speaker’s sound forwards, and helps balance things out a little bit. My plan is to get some plywood, paint them black, and put them under the TV to raise it up. On my model the Arc completely hides the stand, so I’ll never see the gap unless I’m walking to the side of it.

Thanks for your suggestions. I have decided to make one myself.
