My center channel speaker doesn’t have a place to accept a wall mount on the back of it. I originally tried using a couple 6” shelf brackets to support the speaker, but it didn’t look great, especially when compared to the other speaker mounts.
After some thought I ended up building a small half box out of 1/4” MDF. The construction was pretty simple and then I finished it off with flat black spray paint to match the speaker. The end result is that don’t really notice the box around the speaker and it looks great!
In the photo below you can see the undried fill holes from the old shelf brackets. They stuck down pretty far below the speaker.
