Review on Universal Soundbar Mount by Barkan - Adjustable Bracket for Mounting Above or Under the TV - Fits Sizes 13-80 inch - Supports Most Sound Bars Up to 14 lbs - Easy Assembly - Black by Chris Bradford

Pretty smart system but terrible implementation. First, the screws holding the two levers together are too long. This means that the bolt extends quite far beyond the arms. The VESA mounting holes on my TV are recessed slightly into the bottom of the TV, so these screws got in the way of installation. Also, the soundbar mounting system is pretty flimsy, so the soundbar sags a bit (although I like how they designed the tensioning system). I ended up just using the lower control arms and various spacers to install them. You can always look for a better solution or just mount it directly on the wall and you're done.
