Like at least one other reviewer, I had a very hard time figuring out in early September 2020 if and how these brackets were actually (as advertised) compatible with a Bose TV. speaker (which I bought at the same time). The instructions that came with my order did not cover the (then new) Bose TV speaker. I painstakingly spent a lot of time on the internet (looking through instructions for other non-Bose mounts that actually apply to the Bose TV speaker) and talking to Bose customer service and I finally figured it out, but it definitely wasn't worth trouble. I hope that in the past few months Bose has updated the instructions that came with the bracket to cover the Bose TV speaker.
