Skerdi, welcome back. As John B. pointed out, the QS4s are supplied with brackets for mounting flat to the wall. That type of mounting is recommended in most cases since the speakers don't have to point directly at the listener's ears. If for some reason that you haven't mentioned you want a tilting/swiveling mount, possibly a unit such as this one from MonoPrice may be suitable if it can handle the weight. .

Enjoy the music, not the equipment.
