The brackets are a heavy-duty speaker wall mount with pan and tilt functionality. This bracket supports loudspeakers weighing up to 45 kg (100 lbs.) and has a design factor of 7:1.
Its speaker adapter and wall mount plate are installed separately and coupled very easily by just one person. In all brackets of this series, tilt adjustments are achieved using a self-locking mechanism holding the speaker in place, even with all the bolts fully released.
