If you've got a sound bar speaker, here's a great way to mount it neatly and cleanly on top of your flat-panel TV without drilling holes in your wall. The CSB-3205-PRO speaker shelf attaches directly to the top of your TV, and provides a stable spot for your sound bar. You can free up space on your component rack, or wall-mount your TV and do away with the rack entirely.
This shelf is designed for sound bar speakers with a maximum depth of 5". Thick rubber caps at the end of the legs tighten against your TV to keep the shelf securely in place. You can also adjust the mounting screws to angle the speaker down towards your listening position for better sonic performance.
