Amazon sells a set of universal soundbar mounts that allow you to attach basically any soundbar to any TV, hence the universal aspect. Has anyone used these before? I'm thinking about ordering a set as I have a few soundbars coming and I like the idea of having them mounted above the TV in the same fashion while I do my shoot out. Also, I like the idea of mounting the soundbar above the TV directly to the panel rather than to the wall for a nice clean look. Any reviews or thoughts would be appreciated.
